摘要
对重型车辆电液伺服控制双路制动器系统进行了分析与设计。采用电液伺服控制的双联制动阀控制双腔制动油缸的双路制动方案,实现车辆的行车制动和紧急制动。通过分析制动器系统各组成模块和连接管路对制动性能的影响,建立了制动器系统的非线性数学模型。应用MATLAB/Simulink对系统的双路行车制动性能进行了仿真研究,验证了设计方案的合理性。台架试验表明:所设计的制动器液压系统的性能达到了设计要求。
A dual-pipeline brake system controlled by electronic-hydraulic servo was developed for the heavy-duty vehicle.The steering brake and the emergent brake of the vehicle were realized by a dual-pipeline brake system in which an electronic-hydraulic servo controlled dual brake valve is used to control the dual-chamber brake cylinder.A nonlinear mathematical model was built for the brake system through analyzing the effects of the composing modules and linking pipelines of the brake system on the brake performance.The dual-pipeline steering brake performance of the system was simulated using the software MATLAB/Simulink and the result proved the rationality of dual brake scheme.The test-bed tests showed the performance of the developed brake hydraulic system meets the requirements of design.
