摘要

首先,建立对标车架有限元模型,对对标车架进行了模态、刚度性能仿真,并对对标车架进行了模态、刚度试验,验证了该车架有限元建模方法可用于新款车架的开发;针对新开发车架一阶扭转模态、弯曲刚度性能不满足要求,进行了车架优化设计,从增大梁截面与增加内部加强件两方面分别提出改进方案;应用普氏分析法,选用最佳优化方案,完成车架结构集成性能开发。

Abstract

Finite Element Analysis（ FEA） model of benchmark frame was established and the FEA model was validated by mode and stiffness test; The new develop frame’s mode and stiffness performance was evaluated by this FEA model. For the first torsion mode and the bending stiffness does not meet the requirements of SSTS,optimization design was carried out. Two optimization of increasing cross section and adding new part inside was proposed to improve the frame mode and stiffness performance; ProcessedP latts analysis to select the best optimization and completed the frame structure integrated performance development.
