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
