Cylinder designed to be used with hydraulic fluids at generally higher pressures (of around 100 bar and above). Given the relatively low compressibility of the fluid and the low weight of a piston, hydraulic cylinders offer high dynamic performance (generally >600 Hz), which means the dynamic performance of a cylinder drive is largely determined by the load with which it forms a system capable of oscillation (servo cylinder).
Hydraulic cylinder with piston:
The mechanical force is generated by the action of the hydraulic fluid on a piston.
With this approach, a single cylinder is able to apply forces ranging from just a few N to up to 300,000 kN during strokes ranging from just a few cm to over 20 m.
There are 3 basic designs available: single acting cylinders and double-acting cylinders with 1 or 2 piston rods. There are also numerous special forms.
The load for a hydraulic cylinder is based on the respective load model.
In terms of the design, a distinction is made between:
