横置动力总成悬置系统的布置设计分析

以横置的动力总成悬置系统为研究对象,系统地阐述了悬置系统的布置设计思想,解释了悬置系统中主惯性轴、扭矩轴以及弹性轴的定义,并对目前横置动力总成悬置系统的主要布置形式进行了研究与分析。在怠速扭矩激励下,悬置的安装位置应满足系统的扭矩轴和弹性轴重合,从而获得良好的隔振性能。同时对悬置系统的解耦作了相关的说明。横置动力总成悬置系统的布置设计分析,为悬置系统前期开发中悬置的安装位置和刚度的选择提供了参考价值。

Layout Design for Transversely Power Train Mounting System

Layout design for power train mounting system with power train transversely mounted was presented. The definition of main inertial axes,torque roll axis and elastic axis in the transversely PMS were described. The current main layout design for transversely PMS was also discussed. The locations of mounts should be confirmed to make the EA coincide with the TRA to get a pure decoupled pitch mode at idle. Then the stiffness of mounts can be optimized by the kinetic energy distributions to decouple the power train vibration in six directions for each vibration mode to the best of possibilities. Layout design developed in this paper for transversely PMS can be applied to confirm the locations and stiffness of mounts in the earlier developing stage.
