摘　　要：为了提高迫击炮的自动化程度,设计了一种协调臂的迫击炮前装填系统。该系统利用抱弹筒携带弹药,并且在协调臂的转动下携带弹药至炮口处装填。该系统利用协调臂来实现自动化装填,可以完成15发/min的装填技术指标,研制的原理样机验证了方案可行性。为解决原理样机中出现的协调臂振动与抱弹筒的摆动问题,建立了多体动力学模型并进行仿真。根据仿真中出现的问题对系统结构针对化的改进,并对改进后的系统进行多体动力学仿真,仿真结果表明改进后的系统装填性能有较大提升,该系统可以达到所设计的装填性能指标。该迫击炮协调臂前装填系统为迫击炮的无人化自动化提供了新的方案。To improve the degree of automation for mortars,a coordinating arm for mortar front-loading system was designed.This system uses an ammunition-holder to carry ammunition to the muzzle under the rotation of the coordinating arm,providing automatic loading capability that meets the technical requirement of 15 rounds per minute.A feasibility study of the proposed solution was verified using a prototype,and a multi-body dynamics model was developed and simulated to address issues of arm vibration and ammunition-holder swinging observed in the prototype.Based on findings from the simulations,targeted improvements were made to the system structure and multi-body dynamics simulations is carried out,and the simulation results show that the loading performance of the improved system is greatly improved,and the system can achieve the designed loading performance index.The coordinating arm for mortar front-loading system presented is a novel solution for unmanned mortar automation.
