英文摘要：

A kind of dynamic analysis and design method of high-speed slider-cam cigarette separation system was presented. Based on the dynamic model of slider system, the cam controlling movement of slider was designed, and the 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 showed that the method of analysis and design can reflect the characteristics of high-speed slider-cam separation system well, 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.
