【摘要】 迈步式超前支架是综掘巷道临时支护手段的一个发展方向。建立超前支架-顶板支撑系统动力学模型。利用Wilson-β直接积分法对模型进行数值求解。基于ANSYS有限元分析软件对超前支护-顶板系统在矿震荷载下的结构响应进行仿真分析,得到的结果对超前支架动态设计具有一定指导意义。更多还原

【Abstract】 The walking advanced support is one of the developing ideas for temporary supporting in the fullymechanized drift excavation. The dynamic model of the advanced support-roof system is built up,and its digital solution is obtained by Wilson-β direct integration algorithm. The simulation of the system under mine shock is carried out by ANSYS finite element analysis software. The study provides some guides for dynamic design of the advanced support.更多还原
