摘　　要：基于多体动力学理论,建立了变速器动力学振动分析模型。在综合考虑壳体加载状态及各零部件所引起的系统叠加变形的基础上,分别对实际工况下变速器轴承、壳体、轮齿等对变速器振动响应的影响进行了分析研究,并提出了轴承及齿轮宏观参数的优化方案。该方案降低了壳体的变形及齿轮副错位量,提高了齿轮副啮合质量,最终改善了变速器振动响应特性。Based on the theory of multi-body dynamics,the transmission dynamic vibration analysis model is built. The influence of bearing,box and gear teeth on the transmission vibration response is studied respectively. The macro optimization scheme for bearing and gear is put forward,considering loading status and system deformation caused by elastic deformation of each component under the actual working condition of the transmission. This scheme reduces the deformation of the box and misalignment of gear pair and improves the meshing quality of gear pair; finally improving vibration response characteristics of automobile gearbox.
