摘要
防护密闭门作为煤矿井下紧急避险系统的关键部件,有着很高的质量要求。文章针对某企业设计开发的防护密闭门,利用ANSYS/LS-DYNA软件,对其抗爆炸冲击性能进行了数值模拟分析;定量分析了该产品的变形、强度和密封性,并通过结构设计优化,大幅提高产品的性能指标,以达到国家规范要求,保证产品在0.6 MPa的爆炸冲击压力下,各项指标安全可靠。
As the critical component of coal mine emergency refuge system, airtight blast door must satisfy high quality requirements. In this paper, the software ANSYS/LS-DYNA is employed to simulate the blast-resistant properties of a developed airtight blast door. The quantitative analysis of its deformation, strength, airtightness as well as the optimal structure design is conducted. As a result, the performance indexes of this airtight blast door are greatly improved and reach national norms, and every index is safe and reliable under the blast load of 0.6 MPa.
