通过分析探头磁路,论述表面粗糙度对磁性应力仪检测结果的影响;并基于应用磁性应力仪对不同表面粗糙度试件进行的检测试验,明确了必须满足的表面粗糙度条件。
By analyzing the magnetic circuit of the probe, the influence of the surface roughness on the test results of the magnetic stress meter is discussed. The surface roughness conditions that must be satisfied are determined based on the test of the magnetic stress tester for different surface roughness samples.
