Book excerpt: "This thesis describes an efficient procedure for calculating three dimensional resonant vibrations and stresses in intermediate and high pressure turbine blade groups. This procedure is capable of calculating all the natural frequencies, mode shapes, and bending stresses in the tangential, axial, and coupled modes of vibration. Simple beam theory is applied to develop a dynamic stiffness matrix. The solutions to this matrix give the natural frequencies and mode shapes for the blade group. Prohl's energy method is used to determine the amplitude of the forced vibrations and the dynamic stresses. A Goodman diagram fatigue criterion is applied to evaluate the probability of blade group failure. Comparing this procedure's numerical results with experimental results for a rectangular beam structure, the largest difference for the first five tangential natural frequencies is 1.2 percent. This method of analysis is simple and can be applied in twenty hours. Sample calculations and results are given for a typical blade group, and the advantages and limitations of this method are discussed."--Abstract.

Available in PDF, EPUB and Kindle. Book excerpt: Fatigue Failures Of Blades Is One Of The Most Vexing Problems Of Turbomachine Manufacturers, Ever Since The Steam Turbine Became The Main Stay For Power Generating Equipment And Gas Turbines Are Increasingly Used In The Air Transport. The Problem Is Very Complex, Involving The Excitation Due To Aerodynamic Stage Interaction; Damping Due To Material Deformation, Friction At Slip Surfaces And Aerodynamic Damping; Vibration Of An Asymmetric Aerofoil Tapered Along Its Length And Mounted On A Rotating Disc At A Stagger Angle. The Problem Is Also Governed By Heat Transfer Analysis And Thermal Stresses.His Book Deals With A Basic Understanding Of Free Vibratory Behaviour Of Turbine Blades- Free Standing, Packetted, And Bladed-Discs. The Analysis Is Based On Continuous And Discrete Models Using Energy Principles And Finite Element Techniques. A Clear Understanding Of The Interference Phenomenon In A Thin Cambered Airfoil Stage In Subsonic Flow Is Presented To Determine The Nonsteady Excitation Forces Acting On The Blades. A Comprehensive Treatment On The Blade Damping Phenomenon That Occurs In Turbines Is Given. The Nonlinear Damping Models Account For Material Damping And Friction Damping As A Function Of Rotational Speed For Each Mode. Resonant Response Calculation Procedures For The Steadily Running As Well As Accelerating Blades Are Given.Cumulative Damage Calculations Are Then Outlined For Fatigue Life Estimation Of Turbomachine Blades. The Book Also Deals With Heat Transfer Analysis And Thermal Stress Calculations Which Help In A Comprehensive Understanding Of The Blade Problems.

This book was released on 1971-01-01 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Lloyd’s Register Technical Association (LRTA) was established in 1920 with the primary objective of sharing technical expertise and knowledge within Lloyd’s Register. Publications have consistently been released on a yearly basis, with a brief interruption between 1938 and 1946. These publications serve as a key reference point for best practices and were initially reserved for internal use to maximise LR’s competitive advantage. Today, the LRTA takes a fresh approach, focusing on collaboration by combining professional expertise from across LRF & Group to ensure a frequent output of fresh perspectives and relevant content. The LRTA has evolved into a Group-wide initiative that identifies, captures, and shares knowledge spanning various business streams and functions. To support this modern approach, the LRTA has adopted a new structure featuring representatives and senior governance across the business streams and the LR Foundation. The Lloyd's Register Technical Association Papers should be seen as historical documents representing earlier viewpoints and are not reflective of current thinking and perspectives by the current LR Technical Association.

This book was released on 2022-09-02 with total page 4438 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current Perspectives and New Directions in Mechanics, Modelling and Design of Structural Systems comprises 330 papers that were presented at the Eighth International Conference on Structural Engineering, Mechanics and Computation (SEMC 2022, Cape Town, South Africa, 5-7 September 2022). The topics featured may be clustered into six broad categories that span the themes of mechanics, modelling and engineering design: (i) mechanics of materials (elasticity, plasticity, porous media, fracture, fatigue, damage, delamination, viscosity, creep, shrinkage, etc); (ii) mechanics of structures (dynamics, vibration, seismic response, soil-structure interaction, fluid-structure interaction, response to blast and impact, response to fire, structural stability, buckling, collapse behaviour); (iii) numerical modelling and experimental testing (numerical methods, simulation techniques, multi-scale modelling, computational modelling, laboratory testing, field testing, experimental measurements); (iv) design in traditional engineering materials (steel, concrete, steel-concrete composite, aluminium, masonry, timber); (v) innovative concepts, sustainable engineering and special structures (nanostructures, adaptive structures, smart structures, composite structures, glass structures, bio-inspired structures, shells, membranes, space structures, lightweight structures, etc); (vi) the engineering process and life-cycle considerations (conceptualisation, planning, analysis, design, optimization, construction, assembly, manufacture, maintenance, monitoring, assessment, repair, strengthening, retrofitting, decommissioning). Two versions of the papers are available: full papers of length 6 pages are included in the e-book, while short papers of length 2 pages, intended to be concise but self-contained summaries of the full papers, are in the printed book. This work will be of interest to civil, structural, mechanical, marine and aerospace engineers, as well as planners and architects.
