Research on Simulation and Quantitative Evaluation of Performance of Recoil System Based on Virtual Prototyping of Guns

The important functions of recoil system for guns were analyzed, and the necessity and significance of quantitative evaluation of its performance were demonstrated. Based on analysis of main factors that affect guns performance, three indexes that denote performance of recoil system were put forward. Furthermore, the evaluation of integrated performance was separated into evaluations of three sub-performances, and the relations between integrated performance district and those of sub-performances were studied. On the basis of virtual prototyping, virtual working state parameter and evaluation function were defined, and a new method to evaluate integrated performance of recoil system was proposed with the combination of AHP to achieve weighted coefficients. Quantitative evaluation of performance of recoil system was realized, and simulation and evaluation results suggest the feasibility of quantitative evaluation with virtual prototype and the superiority of virtual prototyping. Finally, the perspective of virtual prototyping technology applied in military equipment in the future was given.
