Formules hydrauliques usuelles
Pression (bar):
F = Force (daN), S = Surface (cm²)
Force (daN):
P = Pression (bar), S = Surface (cm²)
Volume (litres ou dm):
S = Surface (cm²), C = Course (m)
Surface de poussée (cm²) Sp = (∅p)² × 0,7854
Surface de tige (cm²) St = (∅p)² × 0,7854
Surface de traction (cm²) S = Sp – St
Øp = Diamètre piston (cm), Øt = Diamètre tige (cm)
Vitesse de vérin hydraulique (m/s):
Q = Débit (l/min), S = Surface de traction (cm²)
Débit (l/min):
V = Vitesse (m/s), S = Surface de traction (cm²)
Couple (mdaN):
F = Force (daN), d = Distance (m)
