Abstract
In order to improve the working performance of the mining excavators, a new type of hydraulic excavator working device is proposed. The proposed excavator working device possesses main advantages of the Tri-Power structure, whereas the kinematic and dynamic analysis can be greatly simplified. In this paper, the kinematic model and tool force model of the new working device are established, and the working performance simulation is conducted. Simulation results show that the new device has excellent performance of level crowding, translational lifting and tool force, indicating that the proposed working device is feasible. After that, multi-objective optimization is designed based on intelligent optimization algorithm. Compared with performance before optimization, all the concerned objectives are improved, including the tool force, level crowding and translational lifting performance. The optimization result has the important reference for the design and application of the new type face-shovel excavator.
