针对立体库堆垛机的立柱在加减速变化时易出现挠度变形的问题,以单立柱堆垛机为研究对象,基于挠度理论,分析影响立柱产生挠度形变的主要因素;将立柱简化为悬臂梁,推导立柱顶端的摆动方程,并建立Simulink仿真模型;以系统运行效率和稳定性为评价指标,采用遗传算法对堆垛机的速度控制曲线进行多目标优化,并对优化后的速度控制曲线进行仿真分析.研究表明,在堆垛机水平和竖直方向运行到最大距离工况下,优化后的堆垛机运行时间由12.5s减少至11.621 s,系统的运行效率提升7.03%;最大振幅由5.99 mm减少至5.08 mm,在提高运行效率的前提下,系统的运行稳定性提升了15.2%,降低了堆垛机在运行过程中的挠度形变,验证了优化方法的可行性,可为堆垛机的设计研究提供参考依据.
Research on Optimization of the Operation System of the Stacker Crane in the Three-Dimensional Warehouse
In response to the problem of deflection deformation of the columns of the three-dimensional warehouse stacker during acceleration and deceleration changes,a single column stacker is taken as the re-search object,and based on deflection theory,the main factors affecting the deflection deformation of the columns are analyzed;Simplify the column as a cantilever beam,derive the swing equation at the top of the column,and establish a Simulink simulation model;Taking the system operating efficiency and stability as evaluation indicators,genetic algorithm is used to multi-objective optimize the speed control curve of the stacker crane,and simulation analysis is conducted on the optimized speed control curve.Research shows that under the maximum distance operating conditions of the stacker crane in both horizontal and vertical di-rections,the optimized running time of the stacker crane is reduced from 12.5 s to 11.621 s,and the operat-ing efficiency of the system is improved by 7.03%;The maximum amplitude was reduced from 5.99 mm to 5.08 mm.While improving operational efficiency,the system′s operational stability was improved by 15.2%,reducing the deflection deformation of the stacker crane during operation.This verified the feasibility of the optimization method and provided a reference basis for the design and research of the stacker crane.
