摘要：

To accurately reproduce the road load and inertia load in tracked vehicle test bench, the calibration method for test bench load simulation accuracy is studied in this paper. Firstly, the dynamic model of tracked vehicle under complex driving conditions is analyzed. The equivalent inertia model of whole vehicle is established, and the loading model of motor is established by speed tracking method. Then in order to study the error of system inertia simulation under this model, a method of calibrating electrical simulation inertia with standard inertia flywheel set is used to calibrate the system simulation accuracy. In the calibration process, the effect of the resistance moment of the system on the calibration results is eliminated and the influence of original mechanical inertia is taken into account. The response time of inertia simulation is analyzed in both steady state and dynamic states. The calibration results show that the system has high simulation accuracy. The validity of the calibration method is confirmed by the test results of the calibrated system vehicle. © 2019, Society of Automotive Engineers of China. All right reserved.
