增压发动机空气管路中的脈冲,通常是不希望有的,因为它能破坏压气机稳定的工作。本文介绍了一种计算方法,可以用最少的代价,去确定任一管路系统中的脈冲特性。其结果是借助于阻抗的概念取得的。一些边界条件被列出,同时涉及到发动机吸力引起的激振。稳定的工作范围是用一个简易的压缩机模型来确定的。例题中论证了模型实验计算与计量十分接近。
Pulsing a pulse in the engine’s air line is often undesirable as it can disrupt the compressor’s steady operation. This article presents a computational method that can be used to determine the pulse characteristics in any pipe system at the least cost. The result is achieved by means of the concept of impedance. Some boundary conditions are listed, as well as vibration induced by engine suction. The stable working range is determined by a simple compressor model. The example demonstrates that the model experiment calculation and measurement are very close.
