Abstract
A new pipe rupture valve for hydraulic elevator is designed. Mathematical models established for the hydraulic elevator system are used in numerical simulations on the Simulink environment of Matlab kits. The effects of different viscous damping diameters, inlet pressures of pipe rupture valve, and elevator loads on the hydraulic elevator system s dynamic performance are analyzed. Experimental research is also carried out using a hydraulic elevator experiment rig. The numerical simulations accord with experimental results in general. Dynamic performance indexes are assessed by the EN81-2 standard. The results show that the newly designed pipe rupture valve meets the designing requirement for hydraulic elevators.
