Hydraulic Scissor Lift – Multibody, Multi-Domain Physical Model in MapleSim – Maplesoft

Hydraulic Scissor Lift

This model examines the mechanics of a scissor lift. A pressure source supplies liquid through the bottom leg via a spool valve that is initially open. A one-way valve prevents liquid flowing back into the sump from this leg.

This liquid actuates a hydraulic cylinder, which transforms the hydraulic energy into translational motion, actuating the hydraulic ram. Near the end of the simulation, a control signal is fed back to the spool valves which closes the bottom one and opens the top on. Fluid then drains back into the sump.
