摘要
EBS桥模块是汽车桥制动的核心部件,目前国内关于EBS桥模块性能检测气控系统的设计没有统一的标准,检测气路设计标准不同会导致检测数据不一致,使得检测结果无法对比分析。针对这一现状,基于EBS桥模块结构及其工作原理,建立桥模块响应特性检测气控系统的数学模型,包括桥模块气室模型、电磁学模型、运动力学模型,以及测试管路数学模型,利用Matlab/Simulink仿真软件搭建检测气控系统的仿真模型,对桥模块常规及电控响应特性进行仿真,提出响应特性影响因素:管路孔径、管路长度、负载储气罐容积,并进行仿真验证。结果表明:管路孔径、管路长度、负载储气罐容积均会影响响应特性测试参数,其最佳值分别为12 mm、500 mm、1 L。通过与实际检测结果对比,验证仿真模型的准确性及仿真分析的有效性,为EBS桥模块响应特性检测气控系统的设计及完善奠定理论基础。
The EBS axle modulator is the core component of automobile axle braking.At present,there is no unified standard for the design of the air control system for the performance detection of the EBS axle modulator in China.Different design standards will lead to inconsistent test data and test results.In view of this situation,based on the structure of the EBS axle modulator and its working principle,a mathematical model of the response characteristic detection air control system has been established,including the air chamber model,electromagnetic model,kinematics model and inspection pipeline model.The simulation model of the air control system has been built using Matlab/Simulink software.The conventional and electronic control response characteristics have been simulated,the influencing factors of the response characteristics:pipeline aperture,pipeline length,and load storage tank volume have been proposed and analyzed.The results show that:the pipeline aperture,pipeline length,and load storage tank volume all affect the response characteristic test parameters,and their optimal values are 12 mm,500 mm,and 1 L.By comparing with the actual test results,the accuracy of the simulation model and the effectiveness of the simulation analysis are verified,which lays a theoretical foundation for the design and improvement of the EBS axle modulator response characteristics detection air control system.
