摘要/Abstract

摘要： 为了满足车辆电液动力制动系统集成设计要求,以ZL50装载机为例,构造了虚拟样机模型并通过实车试验验证了模型的正确性;在MATLAB/Simulink环境下,建立了多回路电液动力制动系统的液压模型并搭建了相应实验台,实验验证了液压模型的正确性;设计了机械模型与液压系统控制模型之间的参数关联,建立了装载机电液制动联合仿真模型并进行分析。结果表明虚拟样机模型与液压系统模型之间实现了无缝链接,验证了该设计方法的有效性和实用性。

Abstract: For now, when vehicle electro-hydraulic brake system is studied, dynamics system and hydraulic system modeling and simulation are usually separated, and that leads to defects in coupling and relevance. In order to satisfy integration design requirements of multi-body system, taking ZL50 loader as an example, the virtual prototype model was set up, and the correctness of the mechanical model was verified by real vehicle tests. The mathematical model of main system components and the hydraulic model of multi-loop electro-hydraulic braking system was established respectively. The experimental results verified the accuracy of hydraulic model by corresponding bench tests. The parameters between Mechanical model and the hydraulic system control mode were designed, electro-hydraulic brake co-simulation model of the loader was established and analyzed. The results show that the virtual prototype model and hydraulic system model have seamless link, and the effectiveness and practicability of the proposed design method are verified.

Key words: integration design, virtual prototype, electro-hydraulic brake, co-simulation
