Compressibility

Compressibility:
Preloaded spring function

F = Fo + KX

Viscosity

Viscosity:
Shock-absorber function

F = Fo + KX + CVa with 0.1<a<0.4
Functioning separately or together
The two functions can be used separately or in combination in the same product:

Preloaded Spring (Spring function only)
  • Hysterisis of between 5% and 10%
  • Reduced weight and space requirement
  • Force/stroke characteristic is independent of actuation speed
  • Reset time between 1/100 sec and 1/10 sec
Shock Absorbers without spring return (Shock absorbing functions only)
  • Dampening devices
  • Blocking devices
Preloaded spring shock absorbers (Combined spring and shock absorber functions)
  • Dissipate between 30% and 100 % of energy
  • Force/stroke characteristics remain unchanged between -14°F and +158°F
