| Summary: | In order to study the micro-vibration characteristics of satellite platform and the effect of micro-vibration on the payload in space,a six-dimensional disturbance force simulator is designed to simulate the micro-vibration in space. First,the theoretical modeling analysis of the six-dimensional disturbance force simulator was performed. Secondly,the structure design of the uniaxial actuator and simulator model were performed and the finite element simulation analysis was applied on the models.Finally,the uniaxial actuator modal test was carried out and the simulator perturbation force experiment was performed. The results show that the error between the modal test results and finite element simulation analysis results of the single axis actuator does not exceed 2. 46 %; the error between the experimental results of the six-dimensional disturbance force simulator and the results of the disturbance force theoretical analysis is within 5%. Therefore,the six-dimensional disturbance force simulator meets the design requirements. |
