摘要

基于腔体声振特性的动态子系统修改方法,将车辆动力总成悬置系统视为附加于车体上的子系统,揭示出车内噪声声压与悬置弹性元件的刚度、阻尼特性参数之间的直接定量关系。并为确保求解效率且降低对计算环境的要求,采用响应面法对其加以近似处理。进而,以降低车内噪声声压为目标,以悬置弹性元件的刚度、阻尼特性参数为设计变量,建立了悬置特性的声学优化设计模型。最后,以5吨越野集装箱叉车为算例,证实了所提优化设计方法的有效性。

Abstract

Based on the cavity acoustic characteristics of dynamic subsystem modification methods, treating the automotive powertrain mounting systems as subsystems attached to the body, revealed the direct ration relationship of interior noise pressure and the stiffness, damping characteristic parameters of mounting elastic component. And in order to ensure efficiency and reduce the solution of environmental requirements, response surface methodology used to approximate treatment. Furthermore, to reduce vehicle interior noise pressure as the objectives and the stiffness, damping characteristic parameters of mounting elastic component for the design variables, established the mounting characteristic of acoustic optimization design model. Finally, taking 5t rough terrain container forklift truck for example, showed that the optimization of the design method is effective.
