Mechanical Analysis on Destruction of Coal Cutters Guide Shoes

摘要

Some key components' failure often occurs in the process of the use of large-scale mining coal machine, and seriously affects the production of the enterprise.So it is necessary that analysis on the failure mechanical reason of guide shoes with the coal-winning machine by the modem mechanics analysis method.The stress diagram of guide shoes could be got by static analysis with MATLAB, and the dangerous parts of the finite element model with guide shoes appeared after loading.Finally, analysis on the fatigue strength and fatigue life of components under various complex condition, which provide some reference theory basis for the future related product designing, Manufacturing and maintenance.
