Abstract

Abstract: A method for vehicle interior structure noise design in the middle frequency range in early stage of development is proposed in this paper. The dominant cause of structure noise for main transfer path is determined according to the simulation result of the “Digital Mule” vehicle model and the reference vehicle model, and then NVH performance targets for corresponding subsystems are established. The overall target is finally reached by achieving subsystem targets. An example for powertrain induced noise confirms the efficiency of the proposed method.

摘要： 提出一种研发初期中频室内结构噪声设计方法，根据数字“骡子样车”和参考样车模型有限元仿真结果，确定主要传递路径的结构噪声根源并设置相应子系统NVH性能目标，通过子系统性能的提高实现整车目标。最后通过动力总成结构噪声设计实例验证了子系统设计方法的有效性。
