| Abstract: | An explosive bolt capture device is designed for heavy maneuvering reentry vehicle and high load conditions.The separating and capturing process simulation is computed.Capturing reliability test is developed based on gas gun simulating the separating impact,and the reliability is evaluated by capturing test of high speed boundary and low speed boundary.It is concluded that design and simulation of the capture device is correct,and the capturing reliability of single device reaches 0.9999. |
