In order to improve the quality and efficiency of missile design, it would be better to take structure design into account during the prophase of missile preliminary design instead of later phase or detail design phase. This paper presents an approach to implement rapid design, modeling, and automated adjustment for missile body structures by describing missile body structures’ arrangement information and model information with parameters. A rapid missile body structure design module was developed based on NX environment and method above which can achieve rapid structure design, automated adjustment, as well as automated calculation and update of data such as mass, barycenter, and so on. Finally, an instance was presented to illustrate that this method is feasible and effective.
