This book was released on with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract Due to precision, flexibility, simplicity in construction, easy control, higher speed and lower energy consumptions, servo presses have recently become popular in metal forming applications. Servo press technology combines the advantages of hydraulic and conventional mechanical presses without their drawbacks. This study presents design, construction and demonstration of a servo crank press system for metal forming operations. The research involves kinematics and motion optimization, dynamic modeling, structural design and analysis, servo motor selection, automation and control, and operational performances of the servo press. The press used in this work has a load capacity of 50 ton and stroke capacity of 200 mm. Firstly, optimized trajectories of ram scenarios are generated. Then dynamic modeling using Lagrange approach is presented. Next structural model is constructed, and Finite Element Analysis (FEA) of press parts are performed within safety limits. A servo motor with a reduction unit is selected based on dynamic model. After that a new automation system is developed, and Cascade Feed-Forward (CasFF) control is applied. Moreover, four motion scenarios (crank, dwell, link, and soft motion) are employed for the performance assessment of press. Finally, the dynamic model is verified by the experimental results. The research study is carried out under support and grant of an industrial project, aiming to provide know-how to industry and researchers. Key Words: Servo crank press, metal forming, motion design, dynamic modeling, system control

Available in PDF, EPUB and Kindle. Book excerpt: Motion and vibration control is a fundamental technology for the development of advanced mechanical systems such as mechatronics, vehicle systems, robots, spacecraft, and rotating machinery. Often the implementation of high performance, low power consumption designs is only possible with the use of this technology. It is also vital to the mitigation of natural hazards for large structures such as high-rise buildings and tall bridges, and to the application of flexible structures such as space stations and satellites. Recent innovations in relevant hardware, sensors, actuators, and software have facilitated new research in this area. This book deals with the interdisciplinary aspects of emerging technologies of motion and vibration control for mechanical, civil and aerospace systems. It covers a broad range of applications (e.g. vehicle dynamics, actuators, rotor dynamics, biologically inspired mechanics, humanoid robot dynamics and control, etc.) and also provides advances in the field of fundamental research e.g. control of fluid/structure integration, nonlinear control theory, etc. Each of the contributors is a recognised specialist in his field, and this gives the book relevance and authority in a wide range of areas.

Available in PDF, EPUB and Kindle. Book excerpt: Flexible Mechanisms such as slider crank and four-bar mechanisms are modeled and their dynamic instability and optimum design analyzed. The primary aim of the project was a thorough understanding and analysis of conditions of dynamic instability in flexible components of mechanisms and robots. Dynamic instability characterizes the behavior when amplitude of vibrations have a tendency to become unbounded with the passage of time. Other aims of the study included the optimal design of mechanisms on the basis of flexibility and control of stresses and deflections.

Available in PDF, EPUB and Kindle. Book excerpt: A numerical technique is used to analyze the kinematics of the generalized slider crank mechanism and an analytical technique to derive dynamic force equations for that mechanism has been formulated. The numerical technique used for displacement analysis is based on a combination of Newton-Raphson and Davidon-Fletcher-Powell optimization algorithm using dual-number coordinate-transformation matrices. Velocity analysis is performed by using a dual number method. Finally, dynamic force analysis is accomplished on the basis of the dual-Euler equation and D'Alembert's principle. The approach is developed in such a manner that a digital computer can detect when a solution is possible and then solve the whole problem. In addition, kinematic displacements of slider and dynamic forces and torques at each of the joints have been graphed against input crank angles for different offsets. In all the graphs, possible cases have been compared with the ideal case, when the mechanism has zero offsets.

Download or read book Control of Synchronous Motors written by Jean-Paul Louis and published by John Wiley & Sons. This book was released on 2013-02-07 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Synchronous motors are indubitably the most effective device to drive industrial production systems and robots with precision and rapidity. Their control law is thus critical for combining at the same time high productivity to reduced energy consummation. As far as possible, the control algorithms must exploit the properties of these actuators. Therefore, this work draws on well adapted models resulting from the Park’s transformation, for both the most traditional machines with sinusoidal field distribution and for machines with non-sinusoidal field distribution which are more and more used in industry. Both, conventional control strategies like vector control (either in the synchronous reference frame or in the rotor frame) and advanced control theories like direct control and predictive control are thoroughly presented. In this context, a significant place is reserved to sensorless control which is an important and critical issue in tomorrow’s motors.

Download or read book Dynamic Modeling and Vibration Control of a Single-link Flexible Manipulator Using a Combined Linear and Angular Velocity Feedback Controller written by Kerem Gurses and published by . This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of lightweight, thin flexible structures creates a dilemma in the aerospace androbotic industries. While increased operating efficiency and mobility can be achieved byemploying such structures, these benefits are compromised by significant structuralvibrations due to the increased flexibility. To address this problem, extensive research inthe area of vibration control of flexible structures has been performed over the last twodecades. The majority of the research has been based on the use of discrete piezoceramicactuators (PZTs) as active dampers, as they are commercial availability and have highforce and bandwidth capabilities. Many different active vibration control strategies havepreviously been proposed, in order to effectively suppress vibrations. The synthesizedvibration controllers will be less effective or even make the system to become unstable ifthe actuator locations and control gains are not chosen properly. However, there iscurrently no quantitative procedure that deals with these procedures simultaneously. This thesis presents a theoretical and numerical study of vibration control of a singlelinkflexible manipulator attached to a rotating hub, with PZTs bonded to the surface ofthe link. A commercially available fibre optic sensor called ShapeTapeTM is introduced asa new feedback sensing technique, which is complemented by a quantitative anddefinitive model based procedure for selecting the individual PZT locations and gains. Based on Euler-Bernoulli beam theory, discrete finite element equations are obtainedusing Lagrange's equations for a PZT-mounted beam element. Slewing of the flexiblelink by a rotating hub induces vibrations in the link that persist long after the hub stopsrotating. These vibrations are suppressed through a combined scheme of PD-based hubmotion control and proposed PZT actuator control, which is a composite linear (L-type)and angular (A-type) velocity feedback controller. A Lyapunov approach was used tosynthesize the PZT controller. The feedback sensing of linear and angular velocities isrealized by using the ShapeTapeTM, which measures the bend and twist of the flexiblelink's centerline. Both simulation and experimental results show that tip vibrations aremost effectively suppressed using the proposed composite controller. Its performanceadvantage over the individual linear or angular velocity feedback controllers confirmstheoretical predictions made based on a non-proportional damping model of the PZTeffects. Furthermore, it is demonstrated that the non-proportional nature of the PZTdamping effect must be considered in order to bound the range of allowable controllergain values.

Download or read book Dynamic Analysis of Flexible Mechanisms with Clearance written by Mona Abdullah Hassan Ahmedalbashir and published by . This book was released on 2016 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This research is focused on studying the dynamic behavior of a four-bar mechanism with clearance. The presence of clearance in a revolute joint induces impacts between the journal and the sleeve. Therefore, it causes vibration, noise and decreases the efficiency of the mechanism. Two different methods are proposed to eliminate the undesirable effects of clearance in the joint through simulations and experiments. The first method, that is used to eliminate these impacts, relies on attaching a spring to a rigid four-bar mechanism. The impacts are predicted by monitoring the moment of the reaction force in the joint with clearance using MATLAB software simulations. It is shown that the impacts could be easily eliminated using adequate and optimized spring parameters. The optimization of the spring parameters is performed to keep the positive effects of adding the spring (eliminating the impacts) and to minimize its negative effects (high maximum input torque and its high fluctuations). The second method aims at studying the dynamic behavior of the mechanism with a flexible coupler link. The dynamic analysis of the flexible mechanism is investigated using two different materials of the coupler link (aluminum and steel) with two different thickness values for each material (3 and 4 mm for aluminum and 1.5 and 2 mm for the steel). The rigid mechanism is considered in this case with a coupler link made of steel with 5 mm thickness to highlight the difference between flexible and rigid mechanisms. The deformation of the flexible coupler links (using ideal joints) is investigated by measuring the strain values at three different speeds (277, 415 and 554 rpm). The obtained results show that the strain values are significantly affected by the crank speed and the thickness of the links. Experimental tests are performed to measure the accelerations for the follower of the four-bar mechanism using rigid and flexible coupler links. These measurements are done for the case of ideal joint (no clearance) and realistic joint with a clearance of 0.5 mm and 1 mm sizes at the three mentioned speeds for each case. The experimental results are validated through simulation tests using ADAMS software. These results confirm that the flexibility of the coupler has thus a role of a suspension for the mechanism."--Abstract.

This book was released on 2005 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents the results of both analytical and experimental investigati on on active control techniques to damp the vibrations in flexible mechanisms. P ID and Fuzzy control algorithms where investigate on two different mechanisms, a cantilever beam and a four bar rotating mechanisms. A complete electronic setup to interface to the data acquisition system with the control software was desig ned and built. A cantilever beam setup was first constructed and retrofitted with PZT patches. A finite element model was then coded to simulate the free response of the beam. After that two control schemes where designed and tested; a simple PID controll er and Fuzzy logic controller (FLC). The controller where added to the simulatio n and the resulting response was stored. The response of the constructed mechani cal setup was then measured experimentally. The designed controllers where then implemented on a Real Time Data Acquisition system and the system response due t o the effect of these controllers was recorded. A comprehensive comparison betwe en the simulation and experimental response show an exact match. A four-bar mechanism was then constructed. Similar to the cantilever beam case a model was adopted to simulate the system response. A PID and FLC controller was also designed. The resulting simulation response was compared to the experiment al recorded one. To properly asses the effect of the controllers in the four-bar mechanism case t hree performance indicators where introduced. The power spectral density of the response indicates the frequency content of the vibrations and helps evaluate th e effect of the controller in damping the frequencies of concern. The notion of calculating the area under the vibration curve also presented another mean of as sessing the performance of the controllers. Finally the traditional measure of t he peak amplitudes was also utilized.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive guideline on dynamic analysis and vibration control of axially moving systems. First, the mathematical models of various axially moving systems describing the string, beam, belt, and plate models are developed. Accordingly, dynamical issues such as the equilibrium configuration, critical velocity, stability, bifurcation, and further chaotic dynamics are analyzed. Second, this book covers the design of the control schemes based on the hitherto control strategies for axially moving systems: feedback control using the transfer function, variable structure control, control by regulating the axial velocity, wave cancellation approach, boundary control using the Lyapunov method, adaptive control, and hybrid control methods. Finally, according to the contents discussed in the book, specific aspects are outlined for initiating future research endeavors to be undertaken concerning axially moving systems. This book is useful to graduate students and researchers in industrial sectors such as continuous manufacturing systems, transport systems, power transmission systems, and lifting systems not to mention in academia.
