Bi-Axial Damper Test System)

Bi-Axial test rig for MEMs (Multilayered Elatormeric Modules) used for developmental testing and quality assurance of elastomeric interfaces used in the launch vehicles. These elastomers in applications are sandwiched in such a way they transfer the thrust and also isolate the solid rocket motor thrust oscillations. The biaxial systems characterize vibration response at frequencies ranging from 0 to 70 Hz, displacements ranging from 0.05 to 15 mm, forces ranging from 0 to 600 kN in dynamic condition and 0-2000kN in static condition.
