Structural design and stiffness analysis of the robot bound planes

In order to avoid unnecessary costs of the design process, we need to design a leg and debug it in advance. It always allows us to determine that whether the design is reasonable. In this dissertation, aiming at the single leg supporting problem of hydraulic quadruped robot in the process of debugging, we design a robot bound planes with guide rails. The robot bound plane is designed by 3D drawing software UG. Based on the theory of finite element analysis, we analyze the stiffness of the robot by using the specialized analysis software ANSYS. And then the unreasonable place of preliminary design of the robot bound planes is amended and improved. Rectangle steel is installed between two steel stringers. It not only improves the strength, but also improves stiffness of the structure, so as to meet the design requirements. Proved by the simulation and experiments, the robot bound planes can meet the design requirements of the standard, it can ensure the smooth progress of hydraulic quadruped robot legs debugging.
