The best latching rocket retainer was designed according to the feature of a rocket launcher. The magnitude of locking force needed by the rocket launcher was obtained via theory calculation, and structure parameters of the latching rocket retainer were obtained by these. The structural dynamics model of the latching rocket retainer and the rocket launcher was established. Results were obtained by applying different pre-tightening and thickness to locking plate to determine the effect of locking force via simulation analysis, and the dynamic characteristics of multiple launcher systems were studied by simulations based on different locking force. The best latching rocket retainer was obtained by analyzing the dynamic response parameter of the multiple rocket launcher. The calculation results provide the academic basis for the design and analysis of latching rocket retainer of a rocket launcher.
