[Abstract]:This paper summarizes the development of lifebuoys both at home and abroad, and studies and analyses lifebuoys in theory and practice. In theory, based on finite element and dynamics theory, the statics, impact dynamics and thermal protection performance of lifebuoy structures are analyzed. The parameterized model is established by using Pro/E software, and the structure of the lifebuoy is optimized and analyzed with ANSYS, which lays a foundation for the improvement of the structure of the lifebuoy. In practice, the comprehensive performance of the capsule is tested in real life, and the protective performance and survival ability of the capsule in the environment of mine disaster are tested. The main contents are as follows: (1) the structure of the circular joint cabin is designed, and the static stiffness and strength of the lifebuoy structure are analyzed by ANSYS Workbench. The stress cloud diagram and deformation cloud diagram of the structure are obtained by statics analysis, and then the results are analyzed and evaluated, and the maximum deformation and the maximum stress concentration of the cabin under 0.3MPa pressure are obtained. It provides the basis for the parameter setting in the subsequent optimization design. (2) on the basis of static analysis, the structure of lifebuoy is optimized. By using the Design Exploration function of ANSYS Workbench, the influence of different parameters on the deformation and stress of the lifebuoy structure is analyzed, which provides the basis for the optimum design of the lifebuoy structure. The dimensions of the lifebuoy are preliminarily optimized, and the structural stiffness and strength of the lifebuoy are compared before and after the optimization. (3) the impact resistance of the structure is analyzed. The influence of gas explosion under mine on the cabin is simulated by AUTODYN, and the pressure history curve of the cabin subjected to impact load is obtained, and the pressure history curve of the cabin is simplified. On the basis of this, the impact dynamic response of the lifebuoy is analyzed by using LS-DYNA, and the stress and deformation of the cabin and flange under the impact load are obtained. The results show that the optimized cabin meets the requirements of anti-explosion. (4) the thermal protection performance of lifebuoy is analyzed based on ANSYS Workbench. In this paper, the thermal insulation structure of the cabin is put forward and the two thermal insulation modes of the life-saving structure are compared and analyzed in theory. Then the better thermal insulation method is simulated by using Transient Thermal module, and the variation curve of the cabin temperature is obtained. It provides a theoretical basis for the study of the interior system of the lifebuoy. (5) A comprehensive performance test is carried out on the lifebuoy. In order to simulate the high temperature environment under the mine, the manned test was carried out, and the changes of the parameters in the cabin were observed, and the maintenance performance and thermal protection performance of the lifeguard capsule were investigated. The results show that the thermal insulation of the cabin is good, the actual gas consumption is obtained, and the movement of the occupants in the cabin is understood within 106 hours. To sum up, this paper mainly completes the structure design of lifebuoy cabin which is a new type of lifebuoy structure. Then, static analysis of the cabin structure is carried out, and the parameters of the cabin size are optimized on the basis of the static analysis. The anti-explosion performance of the optimized cabin was analyzed by using display dynamics software. Finally, the thermal insulation performance of the cabin is simulated and studied, and a good test result is obtained.
