摘要

摘要: 汽车半主动悬置是中高级轿车和SUV提高舒适性的关键技术。针对两种不同类型的结构参数控制式半主动悬置，分别建立了集总参数模型，综合使用试验法和遗传算法对相关集总参数进行了辨识，分析了两种不同半主动悬置的动特性，试验验证了集总参数建模及辨识方法的正确性，为半主动悬置的选型设计、优化及性能预测分析提供设计方法和手段。

Abstract: Switchable engine mounts (SEM) play a significant role in the design of High-intermediate level sedans and SUVs. Two kinds of switchable engine mounts with orifice tunable and decoupled stiffness variable, respectively, are introduced in this paper. Lumped parameter models are developed and their key parameters are identified by experiment and genetic algorithm. The dynamic characteristics of both on/off modes are simulated and tested for each mount, agreement between the results of the two methods is achieved. Finally, the sensitivity of parameters was analyzed. The present work can provide some reference for the design,improvement and optimization of SEM.
