On the basis of the reliability assessment method of assembly accuracy,this paper discusses the development of assembly accuracy reliability assessment software for mechanical product. First of all,considering the factors such as error source,error propagation of mechanical product,the error propagation state space model based on key points is established,and the approach for calculating the assembly accuracy reliability is proposed. Then,on the basis of simplifying and solidifying the analysis procedure of assembly accuracy reliability,the assembly accuracy reliability assessment software for mechanical product is developed using software platforms such as Visual Studio,Qt,Creo and Matlab,the development procedure and functional modules of the software are presented by analyzing the technology architecture and development environment. At last,the application of the assembly accuracy reliability assessment in a radar antenna array sub-module is given,and the effectiveness of the software is verified.
