Finite element analysis of optimized compound cylinder

  The cylindrical vessels are used for storing fluids at high pressure. If the magnitude of the internal/external pressure is closer to the yield strength of the material used, then no thickness of the material will prevent the failure of the vessel. Hence shrink-fitted compound cylinders are used, which can store the fluids at higher pressure closer to the yield stress of the material. Optimally designed...

Problems in the robot path control caused by AL-7075 chassis distortion and methods of improvement through non-conventional machining process

  In the field of research and manufacturing of control surfaces in robot components using 7075-T6 aluminum alloy, distortion during/after machining occurs because of the material removal forces and residual stresses and it affects robot path control. After the exact inspections, the main factors were found to be the machining strategy parameters in milling operation. This paper first presents flatness...
