Configurable cylinder

The configurable cylinder can be customized via its properties dialog. Almost any combination of piston type (single-acting, double-acting), the specification of the piston rods (double ended, with magnetic coupling or slide) and the number (none, one, two) is possible. An end position cushioning (without, with, adjustable) can also be defined. FluidSIM automatically adjusts the symbol according to the preset configuration. In addition, a load to be moved (including possible static and sliding friction) and a variable force profile can be defined in the properties dialog. In the component library from FluidSIM there are several pre-configured cylinders that can be inserted in your circuit and directly used. Should no suitable symbol be available, then simply choose the component with the most similarity to the required component, open the properties dialog and adjust the configuration accordingly.
