Vibration System

The PME series modal exciter is a portable broadband vibration device with permanent magnet, which is characterized by its small size, light weight, high excitation force, durable structure and convenient operation. The modal exciter is composed of a drive coil, an excitation rod, stainless steel elastic support components, and a magnetic circuit. The system is equipped with DPM series power amplifier, which is with features of high efficiency and low noise.

Features

• Low axial stiffness, high radial stiffness, large displacement design;

• Equipped with an excitation rod, the excitation position can be freely set;

• The excitation direction can be fixed at any position, providing flexible selection of excitation locations;

• Silent mode and forced air cooling are optional to ensure on-site operating performance requirements;

• Perfect system detection and protection functions;

• Preferred series for modal verification applications in aerospace & aviation;

• Optional constant current and constant voltage control mode

Typical application

• General vibration testing;

• Fatigue performance testing;

• Experimental modal analysis;

• Scientific research and teaching demonstration;

• Dynamic response measurement;

• Structural modal testing.
