摘要
针对飞机装配过程中需要柔性运输大部件并对其在承载状态下进行装配作业的问题,提出一种多功能重载自动导引车的一般配置形式。综合考虑智能托架和轮系的承载受力情况,基于车体静力平衡方程和尺寸约束条件提出一种承载力分配方法,基于该方法和渐进结构优化法,对自动导引车的车体结构进行拓扑优化研究并确定一种交叉梁结构设计方案,同时采用多目标优化算法确定了一组关键结构尺寸的最优设计参数。静态承载试验结果表明,经过优化设计的车体结构可以满足工程实际需求。
To facilitate the flexible transportation and manual assembly jobs of large aircraft components under supported state in the assembly process,a general configuration of multi-functional heavy-load Automated Guided Vehicle(AGV)was proposed.Considering the bearing forces of wheels and intelligent brackets,a distribution method of bearing forces was proposed based on static balance equations and size constraint conditions of the vehicle body.The topology optimization research on the vehicle body was carried out based on the proposed method and the evolutionary structural optimization method,and a cross beam structural design scheme was determined.At the same time,the optimal design parameters of a set of key structural dimensions were determined by using the multi-objective optimization algorithm.Results of the static loading test showed that the optimized structure could satisfy the requirements of engineering application.
