Vertical column deflection model and its parameter optimization of double-column stacker

针对当前双立柱堆垛机立柱顶端挠度计算模型精度不高、立柱优化算法效率低等问题,以XHF-B系列1-5T双立柱堆垛机为例,提出了一种新的立柱顶端挠度计算模型和立柱参数优化方法。首先,基于微元法的思想,建立了新的立柱顶端挠度计算模型;然后,对立柱进行了影响参数分析,建立了立柱挠度优化模型,并在此基础上,采用粒子群算法(PSO)对其进行了求解;最后,采用ANSYS Workbench软件,对优化后的双立柱堆垛机进行了有限元分析,并结合有限元分析结果,对理论模型的正确性进行了验证。研究结果表明:堆垛机立柱参数优化后,立柱顶端挠度为8.6199 mm,降低了74.8%,优化效果显著;有限元分析结果显示的立柱顶端挠度为9.1597 mm,与理论计算吻合度为94.1%,验证了立柱挠度优化模型的正确性,可为堆垛机设计提供理论依据。

Aiming at the problems of low accuracy of the calculation model of the top deflection of the column of the current double column stacker and low efficiency of the optimization algorithm of the column,a new calculation model of the top deflection of the column and the optimization method of the column parameters were proposed,taking the XHF-B series 1-5T double column stacker as an example.Firstly,a new calculation model of the top deflection of the column was established by using the idea of micro element method.Secondly,the influence parameters of the column were analyzed,and the column deflection optimization model was established,based on which the particle swarm optimization(PSO)algorithm was used to solve the problem.Finally,finite element analysis of the optimized double column stacker was carried out with ANSYS Workbench software,and the theoretical model was verified with the results of finite element analysis.The results indicate that the top deflection of the column is 8.6199 mm after the parameter optimization of double column stacker,which reduces by 74.8%,and the optimization effect is significant.The finite element analysis shows that the top deflection of the column is 9.1597 mm,which is 94.1%consistent with the theoretical calculation.The correctness of the column deflection optimization model is verified,which can provide a theoretical basis and reference for the design of the stacker.
