    Hydraulics - Derive sideload from cylinder buckling under compression ?

    The design of the application is fixed by the client, so I cannot change that. The sketch is not to scale. The angle between the piston and the horizontal X axis varies from 45 deg to 65 deg from closed to fully extended position. The effective stroke lenght is 52 inches. Extension cycle time...

    Hydraulics - Derive sideload from cylinder buckling under compression ?

    Thank you for your answers, your help is much appreciated. @Dougt115, You described the way to calculate the reactions Fx and Fy. These two are equal to the hydraulic force (in theory). So the radial loads in the piston assembly (on my previous sketch, F_head and F_piston) can only be caused by...

    Hydraulics - Derive sideload from cylinder buckling under compression ?

    Forgot to mention the pistons are pinned at both ends. But you probably figured this :)

    Hydraulics - Derive sideload from cylinder buckling under compression ?

    Hi again, Thanks fo the info. I realize my sketch was lacking some details, sorry for the confusion. I uploaded another sketch for your curiosity. The assembly is viewed from the top. I added quick FBDs on page 2, and page 1 shows the forces I am trying to evaluate in a free body diagram of...

    Hydraulics - Derive sideload from cylinder buckling under compression ?

    Hello fellows, first post here so please be indulgent :) I am working on a hydraulics calculation. The application is a compactor. The piston rod develops an axial force and sees a compressive load which creates buckling. The buckling generates a deflection, which in turn creates radial load at...
