Dynamic Characteristics And Kinematics Simulation For Forestry Walking Robot

In this paper, the history and current situation of the design theory for walking robot at home and abroad are analyzed and summarized, and the future development trend of walking robot is predicted, on this basis, this paper presents a new type of mechanical structure design for forest walking robot, and carries out the structure design and kinematics simulation of the forest walking robot under the'program.Based on the bionics principle, this paper proposes the mechanical structure of walking climbing machine which has a certain application value in agriculture and forestry, which uses leg-based walking institutions to make the robot stable and get higher velocity and lose less energy consumption in the uneven and soft ground, the walking robot uses cam damping body, offsets the vibration of the vertical direction produced by the bottom of the fuselage through the role of cam compensation part and makes the vibration of the vertical direction for the bridge relative to the ground be zero.Based on the analysis of the structural characteristics of walking robot, this paper analyzes the position, velocity and acceleration of walking robot respectively, and solves the kinematic equations of the forest walking robot.In the end, the paper builds the 3D model by using Pro/E software, carries on the finite element analysis and solving to the cam by using ANSYS software, gets deformation situation and stress size of each unit and node during the working process of the forest walking robot, and analyzes the stress results.
