| 摘 要： | 为了提高液压支架顶板管理以及承受较大载荷的能力,必须使液压支架顶梁前端的运动轨迹为水平摆幅最小的近似双扭线。通过对液压支架四连杆机构的运动特性分析,建立了四连杆机构的优化设计数学模型,基于遗传算法求出了使顶梁前端运动轨迹为近似双扭线,且双扭线水平摆幅e最小时的各杆长度及相应参数,并以ZY35型液压支架的设计为例进行了验证。结果表明:利用遗传算法对液压支架四连杆机构进行优化设计可以得到理想的设计参数,生产的液压支架工作状态平稳,支护效果良好。

| Abstract: | In order to improve the capabilities of managing the roof and enduring the load of the standing shield's hydraulic support,the motion trace of the roof beam endpoint should be approximate twisted pair line,and its maximal horizontal swing value should be minimal.In this paper,the motion characteristics for the four-bar linkage of the hydraulic support were analyzed,and its mathematic model for optimization design was established.The length of each bar and the correspondent parameters were determined by gene... |
