Investigation on the model of a new type of bending joint

Presents a new type of bending joint. Discusses the radial deformation and the axial deformation aroused by the fluid pressure. Establishes the static model between the fluid pressure and the bending angular degree. Puts forward the dynamic model between the fluid pressure and the deflection of the joint based on the model of cantilever. Discusses the influence of the outer structure parameters on the dynamic characteristics through simulating the bending joint. The simulating results show that the bending joint can possess good dynamic characteristics by choosing rational structure parameters.
