Abstract:In order to solve the simulation problem of shock working condition of a locomotive fuel tank under fluid-structure coupling, the results of four simulation methods such as the combination of virtual mass method and transient method are compared with the small fuel tank model, and the shock test is carried out based on the standard shock spectrum. At the same time, the simulation results are compared with the test values. The comparison results show that the simulation method combining virtual mass method and transient method is the most accurate to analyze the shock working condition of the box under the condition of fluid-structure coupling. Taking the working condition of 1/3 tank oil height as an example, the three-dimensional stress of this type of fuel tank under shock working condition is calculated. The calculation results show that under the condition of 1/3 tank oil height, the shock stress is less than the allowable stress value, which meets the service requirements. The research results have certain guiding significance for analysing the shock stress of the structure under the condition of fluid-structure coupling.
