Abstract: Combined with the research results of bionic teeth, a three-dimensional virtual model of the working device of a certain type backhoe hydraulic excavator was built in Pro/E software. The kinematics and dynamics of the model were analyzed in ADAMS software. The parameters of the backhoe hydraulic excavator working device were obtained, such as the maximum excavation height, the maximum excavation depth, the maximum unloading height, the minimum turning radius, the maximum excavation force of the stick and the maximum digging force of the bucket. Optimization results of the parameters of the boom of the working device show that the angle between the arc outer line and center line was 65°, and the arc radius of the boom was 210 mm.

Key words: mine mechanical engineering, hydraulic pressure excavator, bionics, boom simulation and optimization
