Abstract

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.
