Abstract A novel test bench was proposed in this paper to realize the determination of the rotation resistance moment between bogie and body. Based on the rotation resistance moment determination principle, the yaw angle mathematic model between bogie and body and the time history function of the yaw angle when the vehicle is running in curves were constructed, and the calculation of actuator displacement control instructions was presented by means of space kinematics. Besides, a real vehicle test was conducted with this test bench. The result shows that there is a slight difference for the rotation resistance moment coefficient between the measured values and calculated values, which verifies the validity of the model proposed in this paper and proves the creditability of the test results using the test bench.
