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。
Transmission is an important part of the vehicle, its lightweight design is already a lightweight vehicle of all types of vehicle design an important part. QX-25L light commercial vehicle aluminum shell gearbox development process, the static analysis of the results have been to meet the design requirements, the road test occurred in the clutch housing fracture failure, it is necessary for the transmission dynamics analysis. The modal characteristics of QX-25L commercial vehicle transmission are mainly studied. The method of combining simulation analysis with experimental test analysis is used to determine the modal characteristics of the transmission, which can be used in the test and calculation of vehicle dynamics Provide basic data support.
