The theory of the cylinder output force is calculated

Cylinder theory refers to the output cylinder in a stationary state, the use of pressure on the piston push or pull on the effective cross-sectional area. The following letters: PI PI, D said cylinder bore, the unit is mm, piston rod diameter D said, the unit is mm; P for the use of pressure, the unit for the MPa. The following formula will ( D /) Write to: ^ the piston area calculation. ^ ^ * D, D the diameter of the square; In view of many netizens question for the above instructions. 。 Single rod of the single-acting cylinder output force of spring return type cylinder pressure theory output thrust Fa =. PI * ^ * D PF spring pressure type cylinder theory return back tension of Fa = F spring pressure output tension Fa = type cylinder theory. π*( Dd) ^ * PF spring pressure type cylinder theory back thrust Fa = F. The single output thrust rod double-acting cylinder theory ( The piston rod out) ： Fa=. PI * D ^ * P theory output tension ( The piston rod return) ： Fa=. π*( Dd) ^ * P。 Double pole double-acting cylinder Fa =. π*( Dd) ^ * P actual output power is transfer of mechanical force on the piston rod.
