内燃发动机部分气缸运行时,动力装置的动力特性,尤其是扭转振动特性有时会显著恶化,甚至危及装置的安全运行。这个问题现已引起有关方面的关切。本文是探讨船舶内燃动力装置部分气缸运行时扭转振动的理论计算方法。该方法也适用于其它动力装置部分气缸运行下的计算。发动机部分气缸运行,就是发动机部分气缸熄火时运行的情况,其中最重要,最常见的是一缸熄火的情况。发动机气缸熄火可以归纳为三种类型: 1.当发动机活塞连杆机构(包括十字头)损坏,而船舶又处在航行途中,此时往往拆除该缸
During operation of some cylinders of an internal combustion engine, the dynamic characteristics of the power plant, especially the torsional vibration characteristics, sometimes deteriorate significantly, and even endanger the safe operation of the plant. This issue has now aroused the concern of the parties concerned. This article is a theoretical calculation method to investigate the torsional vibration of some cylinders of the internal combustion engine power plant. The method is also applicable to the calculation of partial cylinder operation of other power plants. Part of the engine cylinder operation, is part of the engine cylinder flameout operation, one of the most important, the most common is the case of a cylinder flameout. Engine cylinder flameout can be summarized into three types: 1. When the engine piston rod mechanism (including the crosshead) is damaged and the vessel is on the way to navigation, the cylinder is often removed
