Abstract
Aiming at the Multi-layer leather cutting machine,for the more thicker material paved on the table,the cutting resistance are increased and the cutter are to be need much more longer,this caused the cutter chattered easily.In order to solve the problem, the structure analysis are to be done for the main transmission system, the dynamics model of the high-frequency cutting knife shaft system is established according to transfer matrix method of the multibody system.Then combining with boundary conditions, the shaft system of natural frequency are calculated,it helped to do the dynamic equilibrium analysis for the flexible rotor and the slider-crank mechanism, simulation results show that it is good to reduce its inertia force and improve cutting stability through structure improvement for the main transmission system.
