降低活塞式机械由于倾覆力矩所引起的低频振动,目前已成为一个重要的科研课题。本文旨在叙述这方面的研究情况。倾覆力矩的交变分量是活塞式机械的一种主要机械振动源。它不同于惯性力和惯性力矩。人们常常采用许多方法使惯性力和惯性力矩得以平衡,然而迄今为止实际上还没有采用 Reducing the low-frequency vibration caused by the overturning moment of the piston machine has become an important research topic at present. This article aims to describe the research in this area. The alternating component of overturning moment is one of the main sources of mechanical vibration in piston machines. It is different from the inertia and moment of inertia. Many methods are often used to balance the moment of inertia and moment of inertia, but so far have not actually been adopted
