Abstract
Stress evaluation of conical rubber spring system R. K. Luo, B. Randell, W. X. Wu, & W. J. Mortel Department of Product Design Trelleborg-Industrial A VS, UK Abstract The conical rubber springs manufactured by Trelleborg-Industrial AVS is a primary suspension layout used between the bogie frame and the axle box for railway vehicles. The system is subjected to both static and fatigue loads. Both FE analysis and experiments are required to assess the strength and durability of the metal parts of the system. Also the stress profile will indicate where the strain gauges should be located when actual experiments are conducted. The geometry of the component is imported from CAD system to CAE system. Care has been taken to provide a sufficient fine grid to give reasonable results when mesh of the part is generated. Static and fatigue load cases are evaluated separately. Von Mises criterion has been used to evaluate the stress state under the loading conditions. The critical loca
