An Optimization Method of AGV Body Topology Based on Improved Variable Density Method

摘要

Aiming at the problem of large weight coefficient of AGV (Automated guided vehicle) car body at present, taking equal strength and light weight as the research target, the mechanical analysis of car body structure was carried out. The relationship between load distribution and wheel position was obtained by mathematical programming, and the constraint conditions of the topology optimization problem were obtained. An adaptive mechanism was proposed to adjust the moving window according to the change of design variables before and after iteration. An adaptive improved variable density method based on sliding window was established to optimize the topological structure of AGV car body. Finally, the structure simulation and verification were carried out to verify the effectiveness and practicability of the method, which can optimize the performance of the AGV car body structure, reduce the weight of the structure, and then improve the efficiency and rationality of the AGV operation.
