Prototype Testing
- Servo Hydraulic Vibratory Damper Test System
- A precision system with a controlled rotary actuator through a servo hydraulic system.
- Damper Hub is mounted on a rotary actuator and represents the actual mounting condition.
- The rotary actuator is excited through a servo value with known excitations.
Prototype Testing
Natural Frequency Test
Two accelerometers are mounted in phase, one on actuator and the other on Damper inertia ring. Which in turn acts as closed loop circuit.
Axial Pull Test
A precisely controlled press is used to find out the axial force & the adhesive strength of the damper.
Slip Torque Test
Torque applied under static condition on the damper elastic member by fixing either inertia ring or hub & gradually displacing the other to measure the Torsional bonding strength of the rubber element under assembly.
Model Calibration
- Simulation Data
- Damper Heat Load
