Dynamic Stiffness Tester
The Vibrating Dynamic Stiffness Tester is designed to measure the dynamic stiffness of materials, which is the resistance to deformation under dynamic loading, expressed as the dynamic force required to produce a unit amplitude.
The instrument applies a dynamic indentation on the specimen surface via a rigid contact head driven by the vertical movement of the crossbeam. It is used to determine the dynamic stiffness of thermal insulation materials, which is essential for assessing sound insulation performance.
This tester is widely applied in industrial inspection, production quality control, and material research for thermal insulation materials.
