摘　　要：为考核双离合自动变速器(DCT)中阀体、传感器和电子元件等关键零部件在实际道路冲击振动下的疲劳可靠性,基于远程参数控制(RPC)技术,结合美国MTS液压伺服激振器和控制系统,设计并搭建了DCT关键零部件道路模拟试验台。通过在关键零部件附近安装加速度传感器和应变片,结合某企业可靠性试验方法,在襄阳试车场采集了大量载荷谱,并对载荷谱进行了分析和反复模拟迭代,准确快速地再现了DCT关键零部件在襄阳试车场相应试验路段的振动特性,为考核DCT阀体、传感器及电子元件等关键零部件的疲劳可靠性提供了一种行之有效的方法。To evaluate the fatigue reliability of DCT key parts such as valves,transducers and elec- tronic components under the actual road vibration, a road simulation test table for DCT key parts was designed based on RPC technology together with MTS hydraulic servo actuator and control system. By arranging acceleration transducers and strain gauges near the key parts, combining with a reliabili- ty method of some enterprises, a large number of load spectrum was acquired on Xiangyang Automo- bile Proving Ground and analysed in the laboratory, then the final drive signals were acquired through repeated simulation iteration, and the vibration performance of DCT key parts in the corresponding road sections of Xiangyang Automobile Proving Ground was reappeared accurately and rapidly. An ef- fective method for evaluating the fatigue reliability of DCT key parts was put forward from the tests.
