摘要
阐述了矿井提升机的机电制动原理,给出了机电制动器的详细参数和制动性能.此外,设计开发了一个大负载、高响应的机电制动试验平台.试验结果表明,设计的机电制动器制动误差小于9％,制动间隙消除时间小于0.1 s.电机电流输入与制动正压输出呈线性关系,斜率为4.11,截距为0.58,满足矿井提升机正压要求.螺杆位移输出和制动压力输出呈三次函数关系,零误差较小.
Abstract
The electromechanical braking principle of mine hoist is described,and the detailed parameters and braking performance of the electromechanical brake are given.In addition,a large-load,high-response electromechanical brake test platform was designed and developed.The test results show that the braking error of the designed electromechanical brake is less than 9％,and the braking gap elimination time is less than 0.1 s.The motor current input is linearly related to the brake positive pressure output,with a slope of 4.11 and an intercept of 0.58,which meets the requirements of positive pressure of the mine hoist.The screw displacement output and brake pressure output are in a cubic relationship with a small zero error.
