Abstract
..
This thesis is dedicated to investigate the static and
dynamic behavior of a hydro mechanical anti-skid braking
system. The pressure reducing valve and the hydro mechanical
anti-skid control unit work as basic components fulfill the
essential requirements of the anti-skid braking system. The task
is accomplished through investigating the dynamic behavior of
those basic components to predict the operating characteristics
of the complete system over different road conditions.
The study aspires to construct detailed mathematical
models of the main system components in order to predict the
complete system static and dynamic behavior at different
operating conditions. A computer simulation program based on
MATLAB-SIMULINK software was utilized to provide
characteristics of individual components and complete system.
The simulation program was used to investigate the effect of the
design and constructional parameters on the dynamic behavior
of the pilot operated pressure reducing valve; change in inlet
pressure, spring stiffness, damping clearance and study the
mutual effects of the mentioned parameters change. And finally,
prediction of the complete system dynamic behavior.
The pilot pressure reducing valve was statically evaluated
experimentally and used to validate the simulation results.
Comparison between theoretical (simulation) and experimental
results of the effect of the pressure reducing valve showed
agreement.
