Modeling and Simulation Vehicle Air Brake System

Abstract

Air brake system has been widely used in heavy trucks and intercity buses for its great superiority over other brake system. The practical performance of air brake system may be greatly different from if we analyze it with static theory. Thus, it is necessary to build an integrate air brake system model to simulate the process of brake accurately. However, the dynamic mathematic model of air brake system is very complicate, which makes the model hard to be solved. In this paper, the components of air brake system are decomposed to several basic standard pneumatic components, and then build the system based on these basic standard pneumatic components. The standard pneumatic components which are built in the softwareMWorks based on Modelica language include cylinder, nozzle, air reservoir, volume, and air pipe. An air brake system which contains brake valve, relay valve, brake chambers and pipelines is made based on the standard pneumatic components. The simulation results show the dynamic characteristics of air brake system.

An Experimental Study on Hysteresis Characteristics of a Pneumatic Braking System for a Multi-Axle Heavy Vehicle in Emergency Braking Situations

“…However, subassemblies in a loop are connected to each other and affect each other; analysis of individual subassembly seems to be insufficient. In terms of the system level, Selvaraj [17] and He [18] established simulation models of the PBS on two-axle vehicles using AMEsim (Advanced Modeling Environment for performing Simulation of engineering systems) and MWorks, respectively. Pugi and his team [3,19] have conducted in-depth research on the pneumatic braking plant of a railway vehicle and established a complete parametric simulation library using Matlab-Simulink, which makes customizable design possible.…”

“…The disc brake and its design parameters were shown in Fig 11 along with its AMESim model. The disc brake is modeled using the signal library based on the governing equation (4). …”

“…Sridhar [2] Describes the modeling of foot brake valve and predicting the dynamic response of the individual valve.Wu [3] studied the robust of pneumatic brake system in commercial vehicle using AMESim. [4], [5], [6] describes the modeling of system by simplifying the valves and the actuators. This paper describes the detailed modeling of individual valves , and actuators by including all the design parameters, thereby makes the model flexible to study the role of each and every design parameter on system level response.…”
