摘要： 由于罐体倾覆保护装置的相关研究在国内外相对较少，文章基于罐体倾覆保护装置强 度的检验方法展开研究。根据乘用车顶部静压与 45°斜压为依据，对两种方法进行建模，然 后使用有限元仿真软件分别对两种方法进行有限元分析，最终将两种方法的有限元仿真结果 进行变形和应力方面的对比。对比最终结果表明，45°斜压比顶部静压更能检测罐体倾覆保 护装置的强度。

Abstract: Due to the relatively limited research on tank rollover protection devices both domestically and internationally, this paper focuses on the research of testing methods for the strength of tank rollover protection devices. Based on the passenger vehicle roof static pressure test and 45-degree inclined pressure test, two testing methods are modeled. Finite element analysis is then conducted on these two testing methods using finite element simulation software. Finally, a comparison is made between the finite element simulation results of the two testing methods in terms of deformation and stress. The comparison of the final test results shows that the 45-degree inclined pressure test is more effective than the roof static pressure test in assessing the strength of tank rollover protection devices.
