煤矿救生舱正成为矿工井下逃生的重要装备,其结构强度直接决定了矿工的生命安全。为提高救生舱强度,提出了2种不同截面的加强肋,通过力学理论分析比较其性能指标优劣,并用有限元软件ABAQUS进行模拟,验证了理论分析。使用2种不同加强肋引起的最大变形分别为1.385 mm和2.26 mm,根据变形程度的大小同时考虑安装空间,加工难易等实际因素,最终决定采用T形截面加强肋结构。
Coal mine rescue cabin is becoming an important underground miners escape equipment, the structural strength of miners directly determine the life and safety. In order to improve the strength of the rescue capsule, two kinds of reinforcing ribs with different cross sections were proposed. The performance of the reinforcing bars was analyzed by mechanics theory. The finite element software ABAQUS was used to simulate and verify the theoretical analysis. The maximum deformation caused by the use of two kinds of reinforcing ribs are 1.385 mm and 2.26 mm, respectively. According to the actual deformation factors such as installation space and processing difficulty, the T-shaped cross-section rib structure is finally decided.
