A hydraulic cylinder can be simply modeled as a mass between two springs. Systems with a low natural frequency (the frequency at which the system oscillates after a sudden start or stop) have a low spring constant relative to the mass of the load. Conversely, systems exhibiting a high natural frequency have a high spring constant …
