摘　　要：对某款搭载DCT(Double clutch transmission,双离合器自动变速器)的车型在试验场按不同工况进行实车试验,使用两个加速度传感器采集DCT关键部位的振动载荷谱,对采集的信号数据进行处理分析。结果显示:DCT最大振动加速度达到10.37 g,为DCT及其主要零部件结构的CAE分析提供真实可靠的输入边界,对建立DCT载荷谱数据库有重要意义。The paper carries out a real car experiment of the DCT（Dual Clutch Transmission） carried on a car according to different working conditions in the proving ground. It uses two acceleration sensors to collect the vibration load spectrum of key parts of the DCT and analyzes the collected signal data. The results show that the maximum vibration acceleration of DCT can be 0.37 g, which provides a true and reliable input boundary for CAE analysis of DCT and its key parts. It also plays a big role in establishing the DCT load spectrum data base.
