  • In the paper, a new ground based impact experiment system is designed to study the impact phenomenon of probe-cone docking mechanism in the course of spacecraft docking. Firstly, the whole scheme of the system, which includes the composition of the experiment system, experiment process, experimental sample and design of related devices, is given. Then, the frequency characteristic of acceleration and the effect of initial velocity on the impact time are summarized by numerical simulation on the basis of Hertz contact law, and the essential principle to choose the accelerometer for the experiment system is concluded. At last, the experiments of low speed impact are carried out. The experimental results show that the design scheme can meet the demand for measuring the docking impact force.
