In particular applications the piston rod of the cylinder may be subjected
to the peak load; it is then important to control the piston rod diameter in
relation to the stroke that should be made, the force developed by the
cylinder, the working pressure and the fixings. The diagram shown has been
realized considering the worst condition, consisting in a rear hinge fixing
on the cylinder body (in vertical position with the load charging the rod
end) and fork on the piston rod. Given the stroke, the relevant horizontal
line is followed until the relevant line to the piston rod diameter (cylinder
bore) is crossed; from that point, drawing the vertical line till reaching
the x-axis, is obtainable the maximum acceptable peak load. |
