摘要
变速器是车辆的重要组成部分,对其进行轻量化设计已经是各类车辆整车轻量化设计中的重要组成部分。QX-25L轻型商用车铝壳变速器开发过程中,在静力学分析计算结果已经满足设计要求的情况下,路试中出现了离合器壳体断裂的故障,因此有必要对该变速器进行动力学分析。主要研究了QX-25L商用车变速器的模态特性,利用仿真计算分析和试验测试分析相结合的方法,确定该变速器的模态特性,可为该变速箱在整车动力学测试与计算分析中提供基础数据支持。
The transmission is an important part of the vehicle.Its lightweight design is already an important component in the commercial vehicle lightweight design.In the development process of QX-25 Llight commercial aluminum-housing transmission,the static analysis calculations is designed to meet the requirements of the situation,but road test appeared broken clutch housing failure,and therefore must be kinetic analysis of the transmission.The modal characteristics of QX-25 L commercial vehicle transmissions is studied,by using the method of combining simulation and experimental,the modal characteristics of the transmission is determined,the basic data support for vehicle dynamics testing and calculation analysis is provided.
