The fault analysis of the wedge is the focus of the pistol environment test. In order to accurately analyze characteristics of pistol in complex environment,the virtual prototype of pistol was established by combining the ADAMS software and the 3D modeling software UG. The friction factor was parameterized,and the simulation results were matched with the experimental results of high speed photography,and the friction factor was fitted under different environment. Then,the prototype model was built in different environment,and the reliability of the open lock was analyzed. Based on the model the kinematics and dynamics characteristic of the main components were obtained. The results show that considering the influence of the complex environment,the combination of numerical simulation technology,the traditional experimental technology can further improve the reliability of the simulation model and greatly shorten the arms development cycle.
