• Description:
  Damping can occur by three mechanisms: passive damping properties of elastic tissue and tool surface; force-velocity properties of active muscle; well-timed activation pulses that occur when a muscle is in the lengthening phase of the vibration. ( Low freq ). High freq - passive spring series element. Extrinsic (Flexor) creates static grip force. dynamic load - Extensor & Intrinsic. Interphalangeal joint stabilized with co-activation. Transmission of vibration increases with co-contraction. Higher grip force -> higher impedance and higher resonance (muscles stiffened). Higher muscle force higher stiffness lesser is the deformation needed to absorb same energy. Under dynamic loading friction coefficient of articular cartilage reduces. Fast Dynamic load - elastic behavior (approx.). Tougher the component and the greater the volume more strain energy it is likely to absorb. [Description provided by NIOSH]
