摘　　要：本文基于电磁原理和电子技术,研制了一种新型的锤击消应力工具-电磁锤。这种锤击工具能够实现锤击频率和锤击力独立调节,锤击频率f的调节范围为0<f≤10Hz,锤击力可在较大范围内无级调节,是锤击法消除焊接应力有效的工具,适用于大多数钢材的消应力锤击处理,在低塑性金属材料锤击消应力方面优势更加明显。In this paper,according to electromagnetic theory and electronics a new peening tool named as electromagnetic hammer is shown. Electromagnetic hammer which' s peening frenquency and peening stress can be regulate separately is right peening tool applied to welding stress relieving.Almost all kinds of steel relieving stress can be used it,especially high rigidity steels.
