Abstract: To mitigate the task risks of the lunar and deep-space landers caused by the wide··band vibrations of its optics and microwave sensors, the ground simulation test is necessary. In this paper, firstly, a vibration transform structure and a measurement method are proposed and a ground facility for simulating the wide-band angular vibration simulation is developed. With regard to the angular vibration environment for the imaging sensor used for the moon lander, a meas. urement test is carried out. The results show that the simulator can have angular vibrations in a frequency range of 0 to 2000Hz, with a control precision of: ±15%, and the rotational and translational speeds can be also set tO the required values of the lander. The facility has been implemented for validating the performance of optic sensors in the angular vibration environment.
