摘　　要：介绍了MTS四立柱道路模拟系统的组成和其核心算法RPC的原理,利用该设备从两个方面来验证路谱输人道路模拟机进行汽车耐久性试验的可行性,一方面,道路高程在道路模拟机上再现的台架试验,另一方面,路面载荷谱输入到四立柱道路模拟机的台架试验,结果表明,路面高程可以精确再现,汽车载荷谱为期望响应的台架耐久性道路模拟试验模拟效果良好。The four-channel MTS road simulation system and the principle of its core algorithm RPC were presented, the device was used to verify the feasibility of doing a vehicle endurance test with a road profile input to the rig from two aspects, on the one hand, the road profile was reproduced in the road simulation bench test; on the other hand the road load spectrum was input into the rig test of a road simulation device with four columns. The results showed that the road profile can be accurately reproduced, the road load spectrum as the expected response can be simulated with the vehicle endurance test rig exactly.
