Abstract | ||||
ABSTRACT This paper is dedicated to investigate the static and dynamic behavior of a hydro mechanical anti-skid braking system. The system consists of a pilot operated pressure reducing valve and a hydro mechanical anti-skid control unit. The system is designed to fulfill the essential requirements of the anti-skid braking system. The steady state and transient performance of the system and its basic components were investigated considering different operating conditions. Detailed nonlinear mathematical models for the system and its components were deduced considering the tire-ground interface. These mathematical models were used to develop Simulink computer simulation programs. The simulation programs were used to investigate the effect of the constructional and operational parameters on the dynamic behavior of the pilot operated pressure reducing valve; mainly the variation of inlet pressure, spring stiffness, damper radial clearance. The operating characteristics of the braking system with the hydro mechanical anti-skid control unit was investigated and analyzed for the cases of driving over dry and wet concrete pavement. The results are presented and discussed. | ||||
