Aiming at the problem of over-reliance on physical test for index verification in traditional design process of firearms,a method of constructing digital prototype of firearms was proposed.According to the working characteristics and performance indexes of typical firearms,based on the geometric prototype of 3D model,combined with relevant simulation analysis software,the simulation model for multiple functional performance of firearms was established.The fatigue life,shooting accuracy,terminal power,man-machine ergonomics and other content were analyzed,and the specific parameters were obtained.The results show that,firearms digital prototype can realize the simulation analysis from the four dimensions of structure rationality,principle feasibility,indexes attainability and measures availability.The analysis and evaluation of the function and performance of the physical prototype was realized on the computer,which provides a digital means for the structural improvement and performance optimization of the firearms,and can effectively reduce the processing and test rounds in the process of prototype development,and support the improvement of the efficiency and level of the design of the firearms.
