AB  - This paper aims at the problems of poor motion continuity and abrupt acceleration of small diameter deep well rescue robot in the process of motion characteristics analysis. According to the movement characteristics and structural forms of the grasping mechanism and bracket mechanism of the deep well rescue robot, the finite element analysis of the key mechanism is carried out based on Hyperworks-Optistruct solver, according to the analysis results, the specific parameters to be optimized are obtained. And the topology optimization of the key mechanism is carried out, the optimal design scheme of clamping mechanism and bracket mechanism of deep well rescue robot are obtained. The optimization results show that on the premise of meeting the strength requirements, the grid density distribution law is obtained. According to the variation law of lightweight curve, the overall weight of grasping mechanism and bracket mechanism decreases obviously. The whole optimization process is completed and the final optimization result is obtained.
