Mechanical performance analysis and optimization of eccentric shaft of jaw crusher in coal
In order to solve the problems of wear and fatigue of jaw crusher and the failure of eccentric shaft under high load,the mechanical performance analysis of eccentric shaft of jaw crusher is carried out,and the optimal dimensional parameters of eccentric shaft are obtained through response surface optimization,and after optimization,the maximum equivalent stress of eccentric shaft is reduced by 2.2%compared with the pre-optimization,and the maximum deformation is reduced by 3.92%compared with the pre-optimization.The stress concentration is effectively relieved after optimization,which verifies the effectiveness of the optimized design and provides technical support for the reliability and economy of coal mine jaw crusher.
