法国的米克来尔(MIKURERU)公司研制成功金属零件共振频率非接触检测器。使用该检测器可实现金属零件的非破坏性检测。该检测器所采用的振动分析法是以随振动(对金属零件激振,使各种振动模振动)而产生的频率为基础。该频率由材料的弹性系数、构造、缺陷等因素而定。该检测器可在10秒钟内测得10种频率。该检测器备有3个传感器,每个传感器上都装有用于振动的电磁铁和用于测量的微音器。当使传感器于检测件接触时,电子系统控制这一传感器,以高精度(1/10000的解析度)测量零件的共振频率。若使用装入
MIKURERU, France, has developed a resonant frequency non-contact detector for metal parts. Use this detector for non-destructive inspection of metal parts. The vibration analysis method used in this detector is based on the frequency generated by vibration (vibration of metal parts, vibration of various vibration modes). The frequency of the elastic coefficient of material, structure, defects and other factors. The detector can measure 10 frequencies in 10 seconds. The detector is equipped with three sensors, each equipped with an electromagnet for vibration and a microphone for measurement. When the sensor is brought into contact with the test piece, the electronic system controls the sensor to measure the resonance frequency of the part with high accuracy (1/10000 resolution).
