| 摘 要： | 随着科技水平的进步,人们对生存环境要求的日益提高,在发动机产生的公害中,噪声问题已逐渐被重视起来.实践表明,油底壳是发动机中的主要表面噪声辐射源.为了更有效的对油底壳噪声进行仿真研究,建立了机油与油底壳的液固耦合模型,将有限元（FEM）与边界元（BEM）结合起来,探讨了油底壳表面辐射声场的仿真分析方法,研究了结构刚度和结构阻尼等因素变化对其的影响.

| Abstract: | It has been proved that oil pan is a main source of surface radiated noise of engine. In order to make effective simulation of radiated acoustic field, the liquid-solid coupled model of oil and oil pan is proposed combining with FEM and BEM, and the simulating method for surface radiated acoustic field of oil pan is established. Moreover, the effects of stiffness and the damping of oil pan on its radiated acoustic field are analysed. |
