摘要: 提出了高速滑块轮式烟支分离系统的一种动力学分析设计方法。在建立滑块系统动力学模型基础上,设计了滑块运动控制凸轮的升程曲线,计算了锁紧弹簧的刚度。基于结构有限元对凸轮进行模态分析,验证了凸轮设计的合理性,从而避免了系统共振。基于虚拟样机技术对系统进行动态性能分析表明,提出的分析与设计方法可以较好地反映高速滑块轮式分离系统的特性,实现准确可靠的分离运动,在减少系统动力消耗的同时避免了滑块腾跳、运动件过度磨损等现象的发生。Abstract: A kind of dynamic analysis and design method of high-speed slider-cam cigarette separation system waspresented. Based on the dynamic model of slider system, the cam controlling movement of slider was designed, andthe stiffness of locking spring was calculated as well. Based on the structural finite element model, the modal analy-sis of cam was presented and the results verified the rationality of the design of cam; as a result,the system reso-nance was avoided. Based on the virtual prototyping technology,the system dynamic performance analysis showedthat the method of analysis and design can reflect the characteristics of high-speed slider-cam separation systemwell,realize accurate and reliable separation movement,and also avoid the occurrence of such phenomena as sli-der's jumping,excessive wear of moving parts while reducing the power consumption of system.
