摘要
本文给出了工程车辆液压制动阀的工作原理图,经简化建立了一个液压盘式制动回油路数学模型,并通过Matlab的Simulink搭建了其仿真模型,以首钢SGA170吨(载重)矿用车低速制动系统(防止发热过大,高速时采用电涡流制动)为例,给出初始参数并进行动态仿真,通过结果分析,针对回油堵塞的问题,找出了可行的解决措施。
A work schematic of a construction vehicle’s hydraulic brake valve is introduced.After simplifying,a mathematical model of the back oil road of a hydraulic disc brake was built up.Through Matlab's Simulink,to build its simulation model.With the low-speed braking system (to prevent excessive heat,when high-speed,eddy current brake will be used) of Shougang SGA170 t (Load) mine dumper as an example,to given the initial parameters.At last some viable solutions to the problem of the back oil road were found,through the results of analysis,after dynamic simulation.
