Investigation of dinamic processes in the hydraulic braking system of transport vehicle with antilock brake system

Abstract

The modern hydraulic brake system consists of various functional systems and elements such as ABS, EDB, cylinders, electromagnetic valves, filters, pipelines, microprocessors and etc. The processes, occurring in these systems, quickly varied, i.e. speed and pressure of fluid quickly vary in time. The speed of a sound in hydraulic system is much greater, in comparison with the speed of a sound in pneumatic system; therefore the dynamic processes in hydraulic system occur much faster. But if some air occurs in hydraulic system, the dynamic characteristic of it is rapidly changes. The account of physical processes in hydraulic systems, depending on properties of the system and fluid, has the importance evaluating reliability of break systems. [....].
