本文叙述柴油机支承凸缘和柴油机部件(油底壳、缸套和机体部件)支承凸缘的振动频谱的计算方法。这种方法的适用频率范围大于150～200赫兹。而方法的依据是,求算被研究零件所产生的振动能量在柴油机振 This article describes the calculation of the vibrational frequency spectrum of the bearing flanges of diesel bearing flanges and diesel engine components (oil pan, cylinder liner and body parts). The applicable frequency range for this method is greater than 150-200 Hz. The method is based on calculating the vibration energy generated by the studied parts in the diesel engine vibration
