摘要
研制了基于巴氏噪声的曲轴残余应力测试仪,介绍了仪器的组成,以及仪器各部分电路的特点,实验数据表明该仪器测试数据准确可靠。
An immanent for residual stress of crankshaft was developed on the basis of Barkhausen noise.The composition of the instnanent was introduced,as well as the special feature of every part of the instrument. It was found in the test that the testing data was exact and reliable.
