Vibration System

Modal Vibration Exciter PME3

Application

Features

  •  Free-moving coil design, with output force from 2N to 6N depending on configuration;

  • The moving coil mass 9g~15g depending on configuration during modal testing, only a negligible additional mass is added;

  • The resonance frequency of the moving coil is as high as 12000 Hz, and the operating frequency is up to 20000 Hz;

  • It is especially suitable for modal analysis in scale models, small structures, and structures where installation is difficult.


Typical application

  • General vibration testing;

  • Fatigue performance testing;

  • Experimental modal analysis;

  • Scientific research and teaching demonstration;

  • Dynamic response measurement;

  • Structural modal testing.
