摘要
主要介绍汽车动力总成悬置系统性能的评价方法,包含设计阶段的解耦目标分析、动力总成刚体模态分析,重点分析整车阶段基于试验的悬置系统隔振率与整车振动的关系,得出针对悬置系统隔振性能的较为有效、合理的评价方法。
The authors describe the evaluation methods of automotive powertrain mounting system performance, in-cluding the decoupling target analysis of the design stage, the modal analysis of powertrain rigid body, focus on the analysis of relationship between the vehicle suspension system vibration isolation rate associated with the vehicle vi-bration based on experiment, and obtain the more effective and reasonable evaluation for the mounting system per-formance of vibration isolation.
