摘　　要：大型船用柴油机曲轴红套滑移以后 ,船体和轴系分别出现明显的振动和扭转振动。文章根据柴油机动力学原理 ,找出曲轴红套滑移以后 ,振动增大的原因 ,并计算出振动的大小和方向 ,从而寻找解决振动的方法 ,这种计算方法 。After slipping of crank shaft sleeve in large marine diesel engine,there will appear obvious vibration and twisting on the hull and shaft system.This paper gives the causes to increase the vibration,calculation of radiation and direction and measures for overcome the vibration according to dynamics principle of diesel engine.This kind of calculation also be applicable to vibration of diesel engines with different extent of slipping,or even no slipping at all.
