摘　　要：通过测量正三轮摩托车在可靠性试验路面上行驶时的振动和载荷时间历程,采用消除趋势项和和畸点方法进行数据处理,并应用RPC软件完成模拟迭代,建立了正三轮摩托车台架可靠性试验的驱动信号,实现了车辆可靠性试验有效路形在室内的复现,并运用所建立的试验路谱完成了正三轮摩托车室内台架可靠性试验。根据功率谱重合性和采用Miner线性累积损伤理论对其关键部件驱动桥完成的损伤当量计算,对台架试验时间周期与道路可靠性路里程的当量关系进行了研究。This paper built a reliability test equipment driving signal of the normal tricycle through measuring its vibration and load time history on reliability testing road,dealt with the measuring data by eliminating trend item and abnormal points,and completed the iteration using the RPC soft,achieved the reliability indoor test effective road surface of the normal tricycle,and finished reliability indoor test of the normal tricycle using the built road testing spectrum.Study the weight between the indoor testing time on test-bed and on the road test mileage,according to the PSD consistent degree and the damage weight calculation on its key part of drive-axle by using the Miner linear cumulating damage theory.
