随着科学技术的日益发展,机器功率和转速的不断提高.在现代工程技术中振动已成为一个非常普遍的问题,它不仅影响到建筑结构的强度;机械设备的寿命;仪表、器械的使用;操作人员的工作,而且还破坏了安静舒适的环境,产生令人厌恶的结构性噪声,严重地影响着人们的正常生活.因此振动的危害已越来越引起人们的高度重视.现行的减小和控制振动的方法,可归纳为以下三类: With the development of science and technology, the power and speed of the machine are continuously increasing.Vibration in modern engineering technology has become a very common problem, which not only affects the strength of the building structure, the life of the mechanical equipment, the use of instruments and instruments, The operator’s work, but also destroyed the quiet and comfortable environment, resulting in disgusting structural noise, seriously affecting people’s normal life.So the harm of vibration has drawn more and more people’s attention. And methods of controlling vibration can be summarized into the following three categories:
