In order to improve the coordination engagement efficiency while maintaining the high reliability of the coordination engagement action,a reliability optimization design of ammunition coor-dinators was carried out.Considering the main geometric dimensions,manufacturing errors,elastic deformation of important components and other factors,a parametric rigid-flexible coupled dynamic model of ammunition coordinators was established,the failures of the coordination engagement action for coordinators were reproduced through the parametric dynamics analysis,then the performance function corresponding to the coordination failure mode and the reliability optimization design model of the coordinators were built.In order to improve the efficiency and accuracy of solving the coordina-tor reliability optimization design model,a new Kriging model adaptive update strategy was construc-ted and combined with SQP method and performance measure approach(PMA)/reliability index ap-proach(RIA),and the coordinator mechanism reliability optimization design method was proposed.The results show that the coordination efficiency of the coordinators is greatly improved under the conditions that the coordination engagement reliability meets the requirements,and the validity and engineering value of the proposed reliability optimization design method are also verified.
