锻锤工作时的强烈振动,对周围环境和锻锤本身都会产生不良影响。近几年来,各国对锻压机械的振动和防振问题开始给予较多的注意。一些国家,从保护环境的角度出发,已对包括锻锤振动在内的所谓“公害振动”制定了限制标准。有的国家,在新建的锻工车间中有75％～100％的锻锤采用了防振基础。随着生产文明程度和对环境要求的提高,锻锤的防振问题将会逐渐提上议事日程。本文从振动的力学特性、振动的传播和影响、防振基础的结构和计算等方面,对锻锤的振动和防振问题作一综述。
Forging hammer work strong vibration on the surrounding environment and forging hammer itself will have a negative impact. In recent years, various countries began to pay more attention to the problems of vibration and vibration prevention of forging machinery. Some countries, from the point of view of environmental protection, have set limits on the so-called “public nuisance vibrations” including forging hammer vibration. In some countries, 75% to 100% of the forging hammers in the newly built forging shop use the vibration-proof foundation. With the degree of civilization and the improvement of environmental requirements, forging hammer vibration control issues will gradually be put on the agenda. In this paper, the vibration and anti-vibration of the forging hammer are reviewed in terms of the mechanical characteristics of vibration, the propagation and influence of vibration, the structure and calculation of the foundation of anti-vibration.
