摘要	According to the demand of a protecting device of an explosive bolt for structure sizes, a shunt-would protecting device was designed to unlock the redundant connection between a space camera and a satellite. On the basis of the ladder-like profile of the explosive bolt, the protection of explosive bolt on the space camera was implemented by introducing the flexure plate absorb the kinetic energy of bolts to deform. According to the feature of true - curve in the yield stage, the strength limit was used as a threshold to determine the structures to be fail or not, and the ratio of plastic strain to fail strain was adopted to estimate the safety performance of the device. Then, Abaqus/Explicit was used to analyze the protecting effect of device suffering from the collision. Finally, a physical experiment was carried out to validate further the design. The simulation results show that protecting bolts made of TC4 suffer the maximum stress about 897 MPa, less than strength limit; and the maximum strain is about 2.2%, less than allowable plastic strain (about 2.6%). These results indicate that the device endures the impact from explosive bolts with sufficient safety. The experiment shows that protecting plate presents light plastic deformation, and each part of the device has complete structure without a fracture or splinter. The proposed design is characterized by a compact size and effective protecting performance.
