在内燃机燃烧产生的气缸压力把往复运动转变成旋转运动的过程中,作用于发动机运动部件和缸体的力一直处于变化状态,激励柴油机的零部件产生振动并辐射噪声.内燃机是一种用途广阔的主要动力机械,也是最重要的环境噪声污染源之一.世界各国对降低内燃机噪声都极为重视,努力探求在新产品和老产品上开发应用具有减振降噪功能的 In the process of converting reciprocating motion into rotational motion, the cylinder pressure generated by the combustion of an internal combustion engine changes the forces acting on the moving parts and the cylinder body of the engine constantly, and the parts of the diesel engine are excited to generate vibration and radiate noise. Of the major power machinery, is also one of the most important source of environmental noise pollution in the world to reduce the noise of the internal combustion engine attach great importance to strive to explore new products and old products with vibration and noise reduction function
