Air Cylinder Clamping Force Calculation

The clamping force on a bolt is defined as the compressive force a fastener exerts on a joint.

Air cylinder clamping force calculation.

We are include detail study and formulas with calculations in our biw welding fixture design course. Clamping force calculations can be quite complicated. 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.

Enter the diameter of the cylinder bore or the piston and for better precision use the average of the two if possible. 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 diameter of the push rod must. All information contained within the pneumatics online web site is the property of pneumatics online.

F p π d 2 4 10 5 n m 2 π 0 1 m 2 4 785 n 0 785 kn air cylinder pressure force diagram. 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.

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. 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. Here s a look at different types how to calculate force speed and air consumptions available options and when to consider special designs. 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.
