摘要
以ZY2600/07/14两柱掩护式液压支架为工程对象,以顶梁承受集中载荷与面载荷两种边界条件,对支架进行外加载试验研究。根据支架的设计参数确定了集中载荷的大小与作用区域;基于实测的顶梁14处压力分布值,利用Matlab、ANSYS软件分别生成压力分布函数和包含面载荷分布信息的模态文件;在机械系统运动学与动力学分析软件ADMAS和有限元分析软件ANSYS环境下创建了1100mm工作高度的液压支架虚拟样机模型,实现了两种载荷形式的外加载试验。研究结果表明,面载荷外加载更能真实反映支架整体受力状态,是检验支架性能的一种可靠方法,具有重要的理论意义和实用价值。
Taking the ZY2600/07/14 mode two leg hydraulic powered shield supports as the engineering object,based on the concentrated load and surface load exerting on the roof ,the outer load tests are carried.The load and application region is determined by the stents design parameter.Based on the 14 real pressure values ,the pressure distribution function and modal file which contains surface load information are respectively produced by Matlab software and ANSYS software.The virtual sample model that the height of work is at 1100mm is built in ADMAS and ANSYS in order to achieve both forms of the laod tests.The results of research indicate that the outer loading method using surface load is feasible and has a great importantance in both theory aspect and practical aspect,because the load case of the hydraulic support can be reflected actually.
