一、慨述阻尼材料和阻尼减振技术如今已日益成为一个新的技术领域.世界上一些技术先进的国家在近二十年内进行了大量的研究,主要用于结构的减振和降噪.而当今,在工程制造的广阔领域中,结构振动仍是一个主要的问题.由于粘弹阻尼材料具有刚度低,阻尼大,结构轻小,使用方便等特点,因此得到了广泛的应用.在机床行业中,国产卧式磨齿机存在有滑
Firstly, the damping material and damping vibration damping technology are now increasingly becoming a new technology field.Most of the advanced countries in the world have done a lot of research in the past two decades, mainly for vibration damping and noise reduction of structures. Nowadays, structural vibration is still a major problem in the vast field of engineering manufacturing.As the viscoelastic damping material has the characteristics of low stiffness, large damping, light structure, easy to use, etc., it has been widely used in machine tools Industry, the domestic horizontal grinding machine there is a slip
