SVR Random & Vibration Loading Program Vibration test
- Inter outside wave foam including earthquake wave foam directly loading or conduct test by changing speed,
amplitude, frequency. It is hydraulic fatigue tester and vibration tester's operation program which can load random wave foam

• Load, Acceleration Control
  
• Basic wave foam test-SINE, HALE, TRINGLE, RAMP
