Abstract

Abstract: The lower part of the crushing chamber of the single toggle jaw crusher is easy to block when it is used, which directly affects the capacity of the crusher and the service life of the moving jaw plate. The cavity shape of PE1500×1800 single toggle jaw crusher is taken as the research object, and Genetic Algorithm is used to optimize the design of cavity shape by taking the minimum difference of the open-side trapezoidal area between the crushing layer and the discharge layer at the lower part of the crushing chamber as the objective function. On the basis of the optimization design, the virtual prototype model of crusher's working device before and after the optimization is established based on ADAMS, and the motion characteristics of the moving jaw are simulated and analyzed. The simulation results show that the capacity of the optimized crusher is increased by 25.19% while the blockage is reduced, and the movement characteristics of the moving jaw discharge port are also improved.
