Grenade Launchers, Acceleration Control Mechanism Reliability Analysis

In this paper, according to the requirement of the improvment of grenade, the reachear project of the control unit which is used for accelerate is put forward. The analysis of interior ballistics and outer ballistics about the system has been done. The structural design of some motion-control system on the automatic weapon has been done; and then 2-dimensional model and 3-dimensional model has also been product. The dynamic matching relation of some motion-control system on the automatic weapon has been studied. And the dynamical academic calculation about the system has also been done, and the dynamical simulation has also been done by the software system ADAMS. Based on the result, the reliability of the system has been studied.The research and the analysis of the work reliability about the control unit which is used for acceleration, which are in the reliability of motion and the reliability of intensity as the key, which structural feasibility and structural dynamics of the motion-control system are encircled, are done. In this paper, models with object function to measure the dynamic matching relation are established. The influences lead by the change of parameters are studied, structural optimization of some motion-control system on the automatic weapon is done. And the object function controlling the bolt parameters is set up. According as the result of the analysis, the reliability of movement has been studied.The best matching relation between each parameter and the motion of bolt is found out.The basic knowledge about the work reliability of the control unit of acceleration on the advanced grenade is gain by research, which can be used by the improve design of grenade as a reference.
