Abstract: Mathematical
models of pipe rupture valve in hydraulic elevator systems are
established, the valve’s flow cut-off performance and step response
characteristics in hydraulic elevator systems are analyzed on the
simulink environment of matlab kits. A comprehensively experiment
research is carried out using analogous test rig and hydraulic elevator
experiment rig, the numerical simulations coincide with experiment
results in general. The theory and experiment references are provided
for designing pipe rupture valve.
Key words: Pipe
