基于ADAMS/Insight的某微型轿车车轮定位参数优化设计

ADAMS/Insight-based optimization design for alignment parameters of minicar wheel

为了解决某微型轿车车轮定位参数设计不合理的问题,采用虚拟样机技术对其进行优化设计。在ADAMS/Car中建立该微型轿车悬架的虚拟样机模型,并对其进行双轮同向跳动仿真分析。在ADAMS/Postprocessor中分析车轮定位参数随着车轮上下跳动的变化曲线,得出前轮前束角和主销内倾角设计不合理的结论。利用ADAMS/Insight模块进行优化设计,优化后的悬架参数能较好地满足设计要求,从而改善了悬架的平顺性,为进行悬架系统的优化提供了一种可靠的方法。

To solve the problem of improper design of alignment parameters of minicar wheel, the virtual prototype technology is used for optimal design. In ADAMS/Car, a virtual prototype model is developed for the minicar suspension, followed by the double-wheel homodromous bounce simulation analysis. In ADAMS/Postprocessor, the change curve for wheel alignment parameters for wheel up-down hop is analyzed, concluding that the front wheel toe-in angle and kingpin inclination angle are not designed properly. ADAMS/Insight module is adopted for optimal analysis. The optimized suspension parameters can better meet the design requirements, improving the suspension smoothness and providing a reliable method for optimizing the suspension system.
