摘要
针对汽车悬架具有强时变性、强非线性、强非平稳性的动力学特性,讨论了汽车悬架隔振性能评价方法的现状,指出其在数学前提、数据处理方法、表征参数等方面存在的不足。介绍工程隔振系统性能混沌评价的现状,分析汽车悬架隔振性能混沌评价的理论基础和动力学基础,说明基于混沌理论评价汽车悬架隔振性能是可行的。
The dynamic characteristics of automobile suspension are strong time-changing, non-linear and non-smooth. The actuality of evaluation measurement for vibration isolation performance of automobile suspension is discussed, meanwhile the matters in mathematical premises, data analysis methods and characterized parameters and so on are pointed out. The actuality of chaotic evaluation for the performance of engineering vibration isolation system is introduced. The chaos and dynamics theories of chaotic evaluation for the automobile suspension vibration isolation performance are analyzed. The evaluation for the automobile suspension vibration isolation performance based on chaos theory is feasible.
