摘要:
基于弹性地基梁理论,建立了弹性底板上的液压支架底座受力分析模型,以前后连杆力最小、结构尺寸最小、掩护梁弯矩最小、支护效率最高、弹性底板比压最小为5个优化目标函数,通过序列二次规化法对液压支架的整体尺寸设计参数进行优化,实现了不同底板状况下的整体尺寸参数优化,基于MATLAB/GUI可视化编程,实现了程序的可视化.算例分析表明,将底板比压作为优化目标函数对液压支架整体进行优化,在结构尺寸变化不大的前提下,优化结果不仅能满足设计要求,而且力学特性有较大的改善,前后连杆轴力、底板比压、掩护梁弯矩4个参数较优化前平均减少了31.95％.
Abstract:
A stress analysis model of hydraulic support base on elastic floor was established based on the theory of beam on elastic foundation.The optimal variables including connecting rod force,structure size,bending moment of the cover beam,floor pressure and support efficiency were taken as five optimization objectives.Hydraulic support overall size of the design parameters were optimized under different floor conditions through the sequence quadratic planning method.The application of visualization was realized based on MATLAB/GUI visual programming.The example analysis showed that the optimization results not only could meet the design requirements but also could improve the mechanical properties.The four main mechanical parameters include the axial force of the connecting rod,the pressure of the floor and the bending moment of the cover beam decreased by 31.95％ on average.
