Air Cylinder Clamping Force Calculation

Example single acting piston.

Air cylinder clamping force calculation.

The total force delivered from the 4 inch diameter air cylinder with 100 psi of air pressure would equal 12 5664 inches 2 times 100 psi which is equal to 1 256 4 pounds of force. This is can be dependent on a number of factors but is largely a function of the preload force the force exerted in compressing the bolt and the tension force the force exerted in pulling the bolt apart. The clamping force on a bolt is defined as the compressive force a fastener exerts on a joint. Generated force this is the force generated by a piston cylinder of a specified diameter and applied pressure and can be displayed in a choice of different force measurement units.

Clamping force calculations can be quite complicated. Cylinder force calculator imperial units air pressure. The diameter of the push rod must. Sometimes an approximate method is good enough.

We are include detail study and formulas with calculations in our biw welding fixture design course. The force exerted by a single acting pneumatic cylinder with 1 bar 10 5 n m 2 and full bore diameter of 100 mm 0 1 m can be calculated as. To calculate clamping forces by fea method for hydraulic pressure of 3 5 mpa and force of 5570n using ansys software we consider fixture clamp design model from cad software. Therefore for fea import piston clamp lever cad model in ansys static workbench and define contacts between piston small pin and clamp lever respectively.

Understand that the 1 256 4 pounds of force would be on the push stroke only and not on the retraction end of the cylinder. See table below for how much clamping force is available from manual clamp straps of various sizes with a 2 to 1 clamping force ratio to compare with power clamp forces. Enter the diameter of the cylinder bore or the piston and for better precision use the average of the two if possible. Pneumatic cylinders come in thousands of variations.
