Road spectrum rig test

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.
