摘要
Abstract
Vibration is one of the main causes of diesel fuel tank failure in trucks.The vibration characteristics of 400L diesel fuel tank was analyzed based on fluid-structure interaction theory.The ANSYS code was used to analyzed the vibration performance of the tank,and the simulation results were verified by the modal test of hammering.It was found that the maximum difference of the structural modal parameters between the simulation and the test is 13%,which verifies the accuracy of the simulation.The simulation results show that the natural frequencies of the first 6 orders calculated in the free state of the tank structure are slightly greater than the natural frequency in the installation state of the tank,and the natural frequency of the tank decreases with the increase of liquid content.The natural frequency of the tank varies significantly in the liquid volume increasing processes from 0 to 100 L and from 300 to 400 L.When the volume ratio of liquid-to-tank is less than 1/2,the natural frequencies of the tank are higher than the frequency of the critical area,so that the resonance will not occur.When the volume ratio of liquid-to-tank is greater than 3/4,the natural frequency of the tank is close to the standard specified critical value of 30 Hz,and the resonance may occur.So,the tank structure should be optimized so that its natural frequency can keep away from the standard specified critical value of 30 Hz although the tank is fully filled.关键词
