Dynamic Simulation Analysis and Test Verification of Truck Fuel Tank based on Fluid-structure Coupling
摘要
Abstract
In the road test for a light truck, it is found that the fuel tank has the phenomena of solder joint cracking and baffle plate shedding. These phenomena may occur very easily when the fuel tank is nearly 50％ filled. In this study, a fluidstructure coupling method is adopted for modal analysis and random vibration analysis of the fuel tank of the light truck. The result of modal analysis for different liquid-filling ratio of the fuel tank indicates that the modal frequency of fuel-containing tank is lower than that of the empty tank. As the oil injection increases, the modal frequency increases mildly vs. the increase of the order. On the basis of the modal analysis, the vibration of the 50 ％ filled tank is simulated and analyzed. The solder joints'stresses in the horizontal, longitudinal and vertical directions and critical direction are extracted. It is turned out that the calculation error is below 10 ％ compared with the experimental data. So, the correctness of the proposed analysis method is verified.关键词
