Vibration dynamic stiffness tester

2024-05-31 14:28

  Material stiffness, abbreviated as stiffness, refers to the elastic modulus in material mechanics. Dynamic stiffness is the ability to resist deformation under dynamic loads, that is, the dynamic force required to cause unit amplitude.

  The vibration dynamic stiffness tester is designed using recent technology. By raising and lowering the crossbeam, the sample contacts the rigid indenter, forming dynamic indentation on the surface of the sample, and then measuring the dynamic indentation stiffness of the material. The instrument is used to measure the dynamic stiffness of thermal insulation materials, thereby determining their sound insulation characteristics. It is widely used in industrial testing, production quality control, and other aspects of thermal insulation materials.
