基于ANSYS的煤矿立井抢险排水管道安全性评价分析
|
摘要
以810 m煤矿立式抢险排水管道为例,研究排水管路正常运行时所受载荷,利用CAD模型建立了抢险排水管道结构的三维模型,运用ANSYS有限元分析软件对其进行静力学分析,模拟排水管道在给定静载荷作用下在竖直方向上的应力和应变分布状况,并对其安全性进行评价。研究得出排水系统最上端管道的横断面为危险截面,管道结构的最大应力为138.88 MPa,小于其应力极限,验证了管道结构的强度及稳定性,为煤矿立井抢险排水系统的可靠运行提供了依据,并结合安全性和经济性的原则,对下端管道的选材提出建议。
In order to analyze the load of drainage pipelines during normal operation, the 810 m rescue and drainage pipeline for coal mine shaft was taken as the example, the 3D model of drainage pipeline was established by CAD software, and the finite element analysis software ANSYS was used to analyze statics characteristics, simulate the distribution of stress and strain in the vertical direction of drainage pipe under the given static load, and evaluate the safety of drainage pipeline. The results showed that the cross section of the top pipeline was the most dangerous section, and the maximum stress of pipeline structure was 138.88 MPa, it was less than the stress limit, which verified the strength and stability of pipeline structure, and provided a basis for the reliable operation of rescue and drainage system. In addition, combined with the principle of safety and economy, some suggestions were proposed for material selection of lower end pipelines.
