So then what should my "l" be? You were saying earlier that it is from the piston to the rod bearing surface. But shouldn't it be taken from pin to pin when the cylinder is fully extended?
Since the cylinder is supported at the two extremes (rod end and rear end), I don't understand why the effective length wouldn't be the distance from pineye to pineye when the rod is fully extended.
Wouldn't the worst case be when the rod is fully extended out of the cylinder? That seems to be...
Can anyone give me the calculations (or send me to a site) necessary to compute the critical buckling stress for the piston rod of a hydraulic cylinder. I know I'll probably use Euler's formula, but I don't know what to substitute for the "effective length" and "k" values. I've looked in...
I have the 24th ed. It shows the formula P=(pi^2*I*E)/l^2.
I just don't know what to use for the effective length "l".
The cylinder is mounted by two pins (one at end of rod, the other at rear of cyl.) and the open center-center is 202".
Anyway,
I appreciate your help israelkk
I've been looking in Machinery's Handbook and it gives me the calculations for a structural column (i.e. Euler's formula), but I don't know how to relate that to a cylinder. For example, what to substitute for your "k" and "l" values. The google search turned up nothing.
