The optimized design mathematical model was set up based on the optimization of mining performance in certain area and the kinematic and mechanical properties of the working equipment. The parameters of the backhoe hydraulic excavator were comprehensively optimized by using the hybrid algorithm of simulated annealing and penalty function. Compared with the traditional algorithm, the optimization algorithm can effectively combine the advantages of the two algorithms to avoid falling into the local optimal solution and improve the accuracy of the solution. The optimization and simulation of the working device are realized by MATLAB programming. The simulation results show that the optimization method ameliorates the defects of the original design and improves the overall excavation performance.
