Dynamic Analysis and Simulation of Annular Hammer Crusher

Using the theory of collision to make dynamic analysis for the assembly of spindle of pckw0809 annular hammer crusher,and geting the formula of relevant parameters to solve the problem of intensity of the key moving parts of the annular hammer crusher.Through the dynamic analysis,the accuracy of the results of the kinetic analysis was verified.At the same time get the motion parameters of annular hammer.In accordance with the corresponding parameters,carrying out the analysis of the forces on limit crushing position,then drawing the load distribution of maximum stress at the assembly and the force states of key parts.It is showed that the safe factor of parts is enough,which precluded the risks for compressive strength of annular hammer crusher.The result was provided references for the design of annular hammer crushers.So it has immense guiding significance for engineering practice.
