面向变型设计的汽车后桥计算机辅助分析与评估

Derivative-Design-Oriented Computer-Aided Analysis And Evaluation on Vehicle Rear Drive Shaft

变型设计是汽车制造厂迅速对市场需求做出快速反应的重要设计手段。结合某汽车公司变型设计的要求,分析汽车后桥的工作特点,对有限元建模技术、分析方法、内容和步骤进行了研究,提出面向变型设计的汽车后桥分析和评估方法。对后桥进行了静力、动力和随机振动分析,并给出了后桥桥壳的变型设计方案。

To develop derivatives is an important measure for automotive makers to meet market requirements rapidly.Based on one automotive company's derivative design requirements and analysis of operation characteristics of vehicle rear drive shaft,the finite elements modeling technology,analysis method,cotents and procedures are studied,and the derivative-design-oriented computer-aided analysis and evaluation method for rear drive shaft are presented.In addition, static,dynamic and random vibration analysis of the rear drive shaft are analyzed,and the derivative design solution for the rear axle housing is given.
