Mobile Mechanism of Unmanned Ground Vehicle with Innovated Deformable Wheel

According to the function of unmanned ground vehicle (UGV) and the requirements for its running system, a new design of deformable wheel mobile mechanism was proposed. The principle and its special feature were described. The stiffness characteristic of the deformable wheel rim was analyzed using finite element method. Meanwhile, the contact pressure of the deformable wheel rim was calculated by simulation. In the end, the running test using demonstration model was carried out. The results show that the proposed scheme is reasonable and feasible, which would lay the foundations for researching new mobile mechanism and UGV technique.
