Taking the project of a coal company shearer cutting unit＇s reliability research as support, key technology in computer virtual simulation has been studied. Specific measures about ensuring simulation accuracy,improving simulation speed and shortening the simulation time have proposed. Operability of Co -simulation about Pro/E, MATLAB, ADAMS and ANSYS has been greatly improved. With the simulation, weak parts in shearer cutting unit have been found. For example, the planet carriers＇stiffness is insufficient. And shell of shearer has stress centralized. Meanwhile ,a fairly perfect shearer cutting unit drive mechanism has been got ,which ensures the reliability of the process of cutting through improving structure. It has a strong practical value in reducing the cost, saving time and improving quality.
