Turn roller tester is based on the actual working conditions,develops the measurement system which can simulate vehicle actually use statement of frition coefficient,investigates the structural characteristic of the drum test rig, sets up vehicle drive resistance’s equivalence chance test way on the road and the turn tyre tester, introduce totality plan of chassis measure power machine. The system adopt measure power machine come into power, brake system use up power, and can accurate measure revolution parameter of come into and output by speed torque sensor, and put through operation obtain the accurate numerical value of roll resistance coefficient. It’s supply theory parameter wi
