Abstract :
Based on the ANSYS Parametric Design Language (APDL), the parametric FEA optimization technique is applied to a railway electricity generator car body structure optimal design procedure. Parametric finite element model of the car body is constructed using APDL language. The car body structure is optimized. The strength and stiffness of the car body are analyzed before and after optimization. The optimization results show that the car body structure can meet the demands of performance indexes in aspects of strength, stiffness, and etc. This example demonstrates the feasibility and effectiveness of the proposed optimization procedure in parametric and optimization design.
