摘要
针对巷道支护结构拓扑优化设计问题,采用数值模拟方法对该问题进行了研究。首先通过编制程序建立支护结构模型,以支护结构单元材料密度为设计变量,以支护结构柔顺度的最小化为目标函数,支护结构总体积减小的百分比为约束函数,利用OC准则对支护结构进行拓扑优化。最后通过算例,验证了该方法的可行性。
Aimed at the topology optimization design problems of roadway support, the numerical simulation method of the problems have been researched. The concrete paper applies program building relevant support structural model, the mathematical model that unit material density as design variables, the minimum of structural compliance as the objective function ,the volume reduction percentage as the constraint function was established, the topology optimization design of roadway support have been executed by using the optimality criteria method. through an example. Finally,the feasibility of the method was verified
