摘要
为解决穿梭式中型立体仓库的N90型货架立柱设计成本较高的问题,对其截面进行优化。首先将立柱截面参数化,用9个独立参数代表整个截面。随后采用复合形法,考虑截面面积最小同时减小长细比,结合ANSYS分析软件,对8个可变参数对立柱性能的影响进行研究,得到各个参数对货架的影响趋势。通过上述步骤对货架立柱进行截面参数优化。分析结果表明,优化后的立柱截面面积减少了3.1%,长细比减小了2.9%;疲劳寿命提升了16.77%,安全系数提升了4.32%,优化后的货架立柱相比于优化前更加优异。
In view of the problem of the high design cost of N90 rack columns in shuttle-styled medium-sized stereoscopic warehouses,an optimization has been achieved for the cross-sections.Firstly,the column sections are parameterized with 9 independent parameters representing the entire section.Subsequently,the composite method is adopted to consider minimizing the cross-sectional area while reducing the length-to-slender ratio.Combined with ANSYS analysis software,a research is conducted on the influence of 8 variable parameters on the performance of the column,thus obtaining the trend of the influence of each parameter on the shelf.Based on an optimization of the cross-sectional parameters of the shelf columns through the above steps,the analysis results show that the optimized column cross-sectional area has decreased by 3.1%,with the length-to-slender ratio decreasing by 2.9%.The fatigue life has increased by 16.77%,while the safety factor has increased by 4.32%,indicating that the optimized shelf columns are even better in performance compared with those before optimization.
