摘要
现代汽车的高速化和舒适性要求汽车具有良好的动力特性,车架作为汽车的承重结构,其动态特性的好坏在很大程度上反映了汽车的整车特性,因此,汽车车架的模型修改在汽车设计中日趋重要。用灵敏度分析方法对车架的结构参数进行摄动分析,根据分析结果。
The dynamics of an automotive frame affects the strength, stability and comfort of the whole automobile, so it is important to make dynamic model modifications according to the respective demands. It is necessary to analyze the sensitivity of the structure before modifications. Such an analysis can be used to find the structural elements and its sensitive parameters. A modified model is made according to the results of the sensitivity analysis.
