This paper has studied the vibration isolation of divided anvil of forging hammer.
对砧座分层的锻锤进行了隔振研究结果表明：如果上下砧的材料和截面能满足阻抗匹配条件，剩余打击冲量就可以全部透射到下砧中，而保持上砧不动，实现工作台高度稳定；通过支承刚度和阻尼参数的合理选择，一方面能保证隔振效果，另一方面又能确保下砧回弹时不对上砧产生冲撞
The actual data are gathered of anvil amplitude of vibration-isolatedhammers used at home and abroad and an investigation on the operation is also made ofsuch forging hammers used in our country.
汇集了有关锻锤砧下直接隔振后砧座振幅的实际数据，考察了国内砧下直接隔振锻锤的工作情况，由理论分析和实践证实，将锻锤砧座振幅增大到10～20mm既不影响生产操作又不影响打击效率，而能获得良好的隔振效果。
