英文摘要	以JKMD4.5×4型矿井提升机配套的E141A型恒减速制动系统为研究对象,分析了恒减速制动系统工作原理;搭建了恒减速制动系统仿真模型,并通过理论计算验证了仿真模型的可靠性;利用仿真模型模拟了弹簧刚度减小、闸瓦摩擦因数下降、制动器泄漏等制动系统典型故障.仿真结果表明:各主要部件性能下降时,并不能立即引起制动系统故障,而是系统性能退化,这些退化表现为制动系统压力降低、开闸间隙变小或变大等;系统性能退化到一定程度才出现制动减速度不符合要求、制动器不开闸、开闸间隙过大、空动时间过长等故障.; Taking E141A constant deceleration braking system in JKMD 4.5 × 4 mine hoist as research object,working principle of the constant deceleration braking system was analyzed.A simulation model of the constant deceleration braking system was built and reliability of the simulation model was verified by theoretical calculation.Typical faults such as spring stiffness decrease,friction factor of brake shoe decrease and brake leakage were simulated.The simulation results show that performance degradation of main components cannot immediately cause failure of the braking system,but can cause system performance degradation such as braking system pressure degradation,braker clearance smaller or bigger,etc.The braking system performance degradation with a certain degree will cause faults such as unsatisfactory braking deceleration,no braker clearance,too large braker clearance,too long idle motion time,etc.; “十三五”国家重点研发计划资助项目; 8; 55-60; 43
