This paper described two methods on how to predict the radiated noise of engine oil pan.
介绍了对发动机油底壳进行噪声预测的两种方法。
Thus, there is constant circulation of oil between the pan and the working parts of the engine.
因而在油底壳和发动机工作零件之间有机油不断流动循环。
The noise of 4110Q diesel engine and its oil pan, flywheel cover, oil pump, valve chamber has been studied by the analysis system of B&K3560 in the normal Semi-anechoic chamber.
在标准半消声室，用B&K3560噪声测量分析系统对4110Q柴油机整机和油底壳、飞轮壳、喷油泵、摇臂罩等零部件的噪声进行了台架试验研究。
