AbstractA six-degree-of-freedom disturbance force and moment simulator that reproduces the disturbance forces and moments that are generated by a reaction wheel assembly is presented. The simulator has considerable application potential in ground-based micro-vibration experiments. The detailed structure of the proposed simulator is first introduced and the simulator model is then established. Using this model, the dynamic relationships between the actuator forces and the disturbance forces and moments can be derived. Because of parameter uncertainties, a closed-loop iterative control method based on a dynamic model is developed, and the effectiveness of this control strategy is demonstrated through integrated simulations. Finally, the disturbance forces and moments reproduced by the simulator are tested using a six-component test platform, and the experimental results show that the maximum relative error between the measured value and the target value is 3.33%, thus demonstrating that the simulator can reproduce the disturbance forces and moments well.
