基于MotionView的前悬架试验与优化分析

The analysis of front suspension experiment and optimization based on MotionView

利用Altair公司所提供的Motion View/Hyper Study模块,快速、方便地调用前悬架模型,并对其进行分析.通过前悬架的试验设计,得到因子与响应之间的主效应和交互作用,研究内外拉杆球铰原有坐标变化对悬架性能的影响.悬架经DOE分析后直接进行优化,优化前悬架模型的铰链点得到最佳前束曲线.对优化前后前悬架前束角曲线进行了对比分析,结果表明得到的优化后悬架的前束角曲线与目标曲线更接近.

To optimize front suspension for better ride comfort, MotionView/HyperStudy module provided by Altair was applied to adjust coordinates of internal and external tie rod ball joints of front suspension. Based on the main effect and its interactions with variable parameters,an optimized model of hinge point of the front suspension was proposed. Referring to curves of front and rear beam angle of front suspension,curves from the optimized system coincided with the target curve better.
