汽车动力总成悬置系统布置研究

以提高汽车舒适性与NVH性能为出发点,简述汽车动力总成悬置系统隔振原理,研究悬置系统的结构形式、结构参数、布置数目、布置方式等相关参数,分析这些因素对汽车悬置系统的影响。研究表明,不同的动力总成、车身结构的汽车对于悬置系统的要求不同,影响后期的优化分析与解耦设计,因此需根据不同车型选择不同的悬置系统。

In order to improve the car comfort and NVH performance,the principle of vibration isolation of the automotive powertrain mounting system is briefly described,and the related parameters such as the structural form,structural parameters,layout number,and layout of the suspension system are studied,and these factors are analyzed for the impact of the car suspension system.Research have shown that different powertrains mounting system and cars body structure have different requirements for the suspension system,affecting later optimization analysis and decoupling design.Therefore,different suspension systems must be selected according to different car models.
