用途:
1. Dynamic and impact-force measurements on small structures.
2. Measurement of frequency response functions using both impact and continuous excitation techniques.
3. As part of a dynamic structural testing system for modal analysis and the prediction of structural response.
 
特性:
1. Compact size and low weight allied with an all-welded, robust construction.
2. Good linearity.
3. Excellent, long-term stability due to artificial aging.
4. Individually calibrated and easily mounted.
5. Easily attached to the stinger and hammer kits.
6. Negligible changes to dynamic properties of test structure.
7. Comes with all necessary accessories for every type of mounting.
8. Titanium tip seating to minimize lateral deformation of tip material during impact.
9. Aluminium shaft to reduce occurrence of double impact.
10. Charge mode (PE) output.
