The compensation method for inertia force of load system of a vehicle steering test bench was studied. Through mechanism modeling, the mathematical model of the vehicle steering test bench was established, and the corresponding transfer function was derived. The coupling between steering gear drive system and loading system was analyzed. According to the decoupling principle of feed-forward compensation, the feed-forward compensation decoupling controller was designed to eliminate the inertia force of the loading system. Finally, Simulink simulation was conducted for the model before and after the compensation of the loading system. The simulation results showed that after adding the feed-forward compensation decoupling controller, the loading system has a higher tracking accuracy at different frequencies, and the inertia force is better compensated.
