| 摘 要： | 装载机向着重载高速智能化方向发展,对其制动系统提出了更高的要求.动力制动系统以其优越的制动性能及可靠性被广泛应用于工程装备领域.本文分析了全液压湿式制动系统的工作原理,根据简化后的制动系统工作原理,建立了全液压湿式制动系统的数学模型,并利用AMESim仿真平台搭建了全液压湿式制动系统的仿真模型.在此基础上对全液压湿式制动系统制动性能进行仿真分析.仿真结果表明:从制动盘与摩擦片开始接触,制动力上升时间为0.1 s,且制动力上升分为3个阶段,解除制动时制动压力下降时间也为0.1 s.蓄能器充满油液后,至下一次充液可以实施约4次制动.活塞在0.1 s的时间内便达到了极限位置0.8 mm.

| Abstract: | The loader develops towards the direction of heavy haul and high speed intellectualization,and calls for higher requirements for its braking system.The power braking system is widely used in the field of engineering equipment for its superior braking performance and reliability.Based on the analysis of the working principle of the hydraulic braking system,this paper establishes the mathematical model of the hydraulic braking system,and the simulation model of the hydraulic braking system using the AMESim simulation platform,and carries out the simulation analysis of it.The results show that the pressure rise time is 0.1 s,and the pressure drop time is 0.1 s when the friction disc contacts with the brake disc,that the brake pressure rise can be divided into three stages when the brake disc is unloaded,that the accumulator can perform about 4 brakes until the next filling,and that the piston reaches the limit position within 0.1 s.0.8 mm. |
