摘要
高压输电线路救援机器人轻量化是其实用性的关键性能之一.以高压输电线路救援机器人机械臂壳体为对象,采用拓扑优化的方法对该结构进行了优化设计,并依据优化结果对机械臂壳体进行了重构和验证分析.通过对重构前后的静应力对比分析表明,在满足强度刚度条件下,重构后的机械臂壳体质量降低了41.40%.研究可为高压输电线路救援机器人轻量化设计提供一种新的思路和方法.
The lightweight design of high-voltage transmission line rescue robot is one of the key indicators of its practicability.Taking the robot arm shell of the high-voltage transmission line rescue robot as the object,the structure is optimized by the topology optimization method,and the robot arm shell is reconstructed and verified based on the optimization results.The comparative analysis of the static stress before and after reconstruction shows that,under the condition of satisfying the strength and stiffness,the quality of the reconstructed robot arm shell is reduced by 41.40%.This study provides a new idea and method for the lightweight design of high-voltage transmission line rescue robots.
