Structural Optimization of Small-Diameter Deep Well Rescue Robot based on Hyperworks-Optistruct

This paper aims to solve the problems related to poor motion continuity and the abrupt acceleration of a small-diameter deep well rescue robot in the process of motion characteristics analysis. According to the movement characteristics and the structural forms of the grasping mechanism and the bracket mechanism of the deep well rescue robot, the finite element analysis of the key mechanism is carried out based on the Hyperworks-Optistruct solver. According to the analysis results, the specific parameters to be optimized are obtained. Moreover, the topology optimization of the key mechanism is carried out, and the optimal design scheme of the clamping mechanism and the bracket mechanism of the 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 the lightweight curve, the overall weight of the grasping mechanism and the bracket mechanism decreases obviously. The whole optimization process is completed, and the final optimization result is obtained.
