Modal Exciter
- Wide frequency band, small size, large excitation force, strong rigidity
- The length of the vibration rod can be adjusted through the movable part through-hole, and the clamp position can also be adjusted, making it easy to connect to the test sample.
- Electronic zero position control allows for adjustable axial stiffness, with little need for additional stiffness to the test sample
- Stroke length can reach 25.4mm, making it ideal for structural tests that require suspension of various rigid structures and Modal Exciters at low frequencies.
Determination of structural dynamic response, modal analysis, component fatigue Test, etc.
