发布时间：2019-08-19 13:10
【摘要】：透水事故是井下常发灾害之一。为满足井下紧急避险要求,救生舱不仅要具备持续耐高水压的能力,而且还需保持良好的水密性。为了检验救水舱的水密及承压性能,应用ANSYS模拟软件对舱体应力变化进行了数值模拟,确定了舱体应力值可能偏大的区域,进而选定了现场试验应变监测点;通过水压试验中心现场试验,制定详细升压方案,观察及分析试验现场和试验应变数据。实验结果表明,救生舱在外界水压达到3MPa的情况下,舱体未发生渗漏及明显变形,救生舱水密及承压性能良好。
[Abstract]:Permeable accident is one of the common underground disasters. In order to meet the requirements of underground emergency risk aversion, the lifebuoy should not only have the ability to withstand high water pressure continuously, but also maintain good water tightness. In order to test the watertightness and bearing performance of the water rescue tank, the stress variation of the cabin is simulated by ANSYS simulation software, and the area where the stress value of the tank may be too large is determined, and then the strain monitoring point of the field test is selected. Through the field test of the water pressure test center, the detailed pressure boost scheme is worked out, and the test site and test strain data are observed and analyzed. The experimental results show that when the external water pressure reaches 3MPa, there is no leakage and obvious deformation of the cabin, and the watertight and pressure bearing performance of the lifecabin is good.
