Abstract

To study the transmission system of the coal winning machine cutting part, the theory of rigid-flex coupled multi-body system dynamics is applied, a method for determining the model parameters is presented. The transmission system dynamics model of rigid-flexible coupling multi-body contact was built in the RecurDyn software environment and exerted in the MATLAB to calculate the actual condition of the load. In order to optimize the simulation results of the gear , the meshing process is described directly and dynamically and the dynamic equivalent levels of gear stress is calculated under the simulation environment. The problems of large mechanical transmission mechanism with flexible contact simulation are solved and proved in the reliability of virtual prototyping technology, more over periodic fluctuations are revealed for the stiffness excitation and meshing gear transmission system.
