摘　　要：为了研究矿用自卸车燃油箱系统,建立了有限元模型,并通过有限元分析软件Adina对不同充液高度的燃油箱系统进行流固耦合数值计算。计算结果表明,随着充液高度增大,燃油箱系统振动频率下降,可见充液高度是影响燃油箱系统的振动频率的主要因素。In order to study the fuel tank system of the dump truck, a finite element model was established, and the fluid-solid coupling numerical calculation of the fuel tank system with different filling heights was carried out by the finite element analysis software Adina. The calculation results show that as the filling height increases, the vibration frequency of the fuel tank system decreases. It can be seen that the filling height is the main factor affecting the vibration frequency of the fuel tank system.

关 键 词：流固耦合 燃油箱 充液高度 固有频率
