摘要
为降低链式弹仓在运转过程中的冲击载荷,减少多边形效应的影响,使传动更平稳,特采用大齿数链轮和小节距链条的方案来进行弹仓设计,基于Creo对弹架、链轮、箱体、轨道等部件进行三维建模,建立了弹仓的总体结构模型。运用拉格朗日第二类方程建立了弹仓的动力学微分方程,并且结合多体动力学仿真软件RecurDyn对其进行运动学仿真,得到了链式弹仓在启动阶段紧边部件和松边部件的动力学响应。通过对两者的各项运动响应的分析,证明该弹仓传动较为平稳,能够满足设计要求。
In order to reduce the impact load of the chain magazine during operation,decrease the influence of the polygon effect,and make the transmission more stable,the method of a large-tooth sprocket and a small-pitch chain is used to design the magazine.The three-dimensional modeling for racks,sprocket wheels,boxes,and rails is established based on Creo,and the overall architecture model of the magazine is constructed.Using Lagrange equation of the second kind,the dynamic differential equations are given.With the multi-body dynamics simulation software RecurDyn simulating the kinematics of the magazine,the dynamic response of the tight-edged parts and the loose-edged parts from the magazine is obtained at the start-up stage.The results show that the magazine has a relatively stable transmission,and meets the design requirements.
