But in many cases, vibration is beneficial tous and should be used. Along with the progress of modern science and technology, vibration reduction, vibration isolation, noise reduction research have got a rapid development and a lotof application have been used inour life. This play a good role in improving product quality and protecting the environment. And the research of vibration using have made great achievements. It get a wide range of applications in engineering field. This result ina batch of using of the vibration of mechanical vibration, and various vibration processing technology. Because of the modern scientific development and course cross, the research and application of vibration using bined with a cultural and engineering field and expand the vibration field. This enrichs the connotation of the vibration engineering discipline and explains people has realized that we can use and control the vibration to change our world. This isa very important change and will promote the development of vibration engineering to benefit mankind. Keywords: vibration; machinery; vibration using engineering 东北大学 Abstract II 东北大学第1 章机械振动简介-1- 第1章机械振动简介 振动振动是在日常生活和工程实际中普遍存在的一中现象,也是整个力学中最重要的研究领域之一。所谓机械振动,是指物体(或物体系)在平衡位置(或平均位置)附近来回往复的运动。在机械振动过程中,表示物体运动特征的某些物理量(如位移、速度、加速度等)将时而增大、时而减小地反复变化。在工程实际中,机械振动是非
