For the situation of provided vibration signal but without tachometer pulses signal, a novel speed curve calculation method based on energy centrobaric IFE method is proposed.

对于没有转速脉冲信号而只有振动信号的情况下，提出了基于能量重心法ife的转速曲线计算方法。

In addition to these tests, we also use a Run out Tester, Digital Measuring Projector, Environmental Test Chamber, Orbital Tester , Infrared Tachometer, Vibration Tester, Decibel Level Detector…etc.

另外，我们也采用马力测试机、标准扭力分析多功能测试机、震动测测试机、分贝器、红外线转速测试机、偏摆测试机等等检验设备，来为产品的质量做最严格的把关。
