为提升汽车驱动桥NVH性能,基于实际工况,从驱动桥主减齿轮传动误差着手,建立了一种驱动桥NVH分析及性能优化方法。基于MASTA软件建立驱动桥精确模型,依据实际工况载荷计算出齿轮啮合错位量;基于实际工况对驱动桥主减齿轮进行TCA及LTCA分析,得到加载接触区及传动误差的变化规律。在此基础上,基于MASTA软件研究了驱动桥NVH仿真分析方法,得到实际工况下的驱动桥噪声曲线。建立了加载传动误差与驱动桥噪声曲线之间的影响关系,通过控制传动误差对驱动桥NVH性能进行了优化。研究为驱动桥减振降噪以及主减齿轮的修形优化提供了理论参考。
In order to improve NVH performance of drive bridge,from the aspect of transmission error,a method of drive bridge NVH analysis and performance optimization is established based on actual working conditions. Firstly,the exactly model of drive bridge is established based on MASTA software,and the gear meshing misalignments are calculated according to the actual load. Secondly,the change law of load contact area and load transmission error is obtained by TCA and LTCA analysis for drive bridge gear based on the actual working conditions. On this basis,the NVH simulation and analysis method for drive bridge is studied based on the MASTA software,and the drive bridge noise curve under the actual working conditions is obtained. Finally,the influence relation between the load transmission error and drive bridge noise curve is established,and the drive bridge NVH performance is optimized by controlling the transmission error. The theoretical guidance for vibration and noise reduction of drive bridge and modification and optimization of main reducer gear are provided.
