Vibration System

Application

The conventional electrodynamic vibration shakers used in traditional testing are bulky and the installation process is cumbersome. In contrast, inertial actuators offer  outstanding portability and mobility. Their compact sizes and easy installation make them ideal for handheld applications, which can achieve fast and efficient measurements.


Features

  • Compact structure, light weight, portable and widely used;

  • Excellent low-frequency performance, capable of installation at any angle;

  • Highly mobility, suitable for handheld use.


Typical application

  • Structural testing of bulkheads of ships and submarines;

  • Vibration and modal testing, automobile abnormal noise testing, building resonance testing;

  • Widely used in civil engineering, shipbuilding and educational research;

  • Active noise reduction and vibration damping applications (using customer-supplied control system), etc.
