Artificial Rapid Replenishment Device Design And Characterization Analysis

In this paper, a shell recharge mechanism of an automatic machine is selected as the research object. The structures of the mechanism are designed and the dynamics analysis is made.With the development of modern auto cannon, the launch speed of artillery is faster and faster and the requirement of the shells' recharging speed becomes higher and higher. However, due to the limitation of electrical machinery speed and power, the shells' recharging speed has become the bottleneck of auto cannon's speed increasing. The past recharging mode is simple and effective, but the shortcomings are higher load while working and too much power consumption and single species of shells. Thus a new type of recharging is needed to reduce load and improve launch speed. The new way is to divide shell box into several units. While the recharging mechanism working, only one unit is on and others are off which not only reduce loads but also supply more kinds of bomb.The following aspects are mainly analyzed in this paper:(1) In accordance with the principle of rapid replenishment device, the overall structure is designed. Some of the major components are checked by using the finite element theory.(2) An appropriate motor is selected to match the system. The transmission and speed reducer is designed in accordance with the structure requirements.(3) Kinematics equations are established according to the principle of mechanical system dynamics. The programming software is used for the dynamics simulation of mechanism.(4)Based on the ergonomic principles, the human engineering design of the shell recharge mechanism is made and its reliability and maintainability are checked.
