Abstract: The current design of the movable jaw structure of the traditional jaw crusher is unreasonable with heavy weight. The parameterized entity modeling of the movable jaw is carried out by using Pro/Engineer Wildfire5.0 software. Through finite element analysis by using the ANSYS software, the response surface method (RSM) is utilized to optimize and analyze the dimension parameters of the movable jaw, and the optimum design parameters are obtained by taking the movable jaw weight as the optimization objective. Under the condition of satisfying the strength, the weight of the movable jaw is reduced about 15.975%. The reliability of movable jaw structure before and after optimization is analyzed by six sigma standard. The results shown that the structural reliability of the movable jaw before and after optimization is maintained, which provides a feasible scheme for the development and optimization improvement of crushers.
