The dynamic capability of compressed-air automatism weapon’s automatic mechanism is examined by the technology of dynamoelectric dynamic simulation trial for automatic mechanism using electromotor for replacing real firing, it has the important practical significance for exploitation of compressed-air automatism weapon.

A generalized modular design of automatic weapon was put forward to improve the quality and efficiency of design,reduce the development cycles of products,and promote the generalization,modularization and serialization of products.

According to the work properties of automatic weapon, the method for simulating automatic weapon which included automatic fire simulation and the handling of complex constraints of automatic weapon on the dynamic simulation software-ADAMS was proposed.

The special dynamical simulation system-ADAMS/GUN for automatic weapon was developed,including the developing process and the realizing method.

The virtual prototype technology is introduced into the simulation area of automatic weapons and the model processing methods are studied on the numerical simulation of automatic mechanisms.

In this paper, the dynamics equations and the general collision equations are set up by R/W through analyzing the kinematics theory of automatic weapons, and the matrix variables are explained in detail.

This paper not only establishes a computing model of the extraction in automatic weapons,but also sets up an extraction measurement system.
