摘要
钻机液压盘式刹车较大的安全系数,导致正常工况下的刹车油压过低。过低的刹车油压使制动力调节灵敏度很差,同时也造成了钳缸、刹车块与液压油的长期无谓损耗。针对这个问题,采用将工作钳缸分组、动态隔离或添加在用钳缸的自动换挡办法,通过AMESim和Simulink联合仿真和实验室试验,实现了制动力低载阶段的精细调压、节能降耗等功能。结果表明:自动换挡调压较好地解决了当前盘刹控制存在的缺点。
The larger safety coefficient of drill rig hydraulic disc brake leads to too low brake hydraulic pressure in normal working conditions. The lower brake hydraulic pressure makes adjustment of braking force too poor, but also causes senseless loss of clamp cylinder, brake block, hydraulic oil in long tenn. A method was proposed to solve this issue, in which brake clamps cylinders were divided into groups, and isolated or added dynamically. Through AMESim-Simulink joint simulation and laboratory experiment, the functions of the fine pressure adjustment of braking force at low load, saving energy and reducing consumption, and others are real- ized. The results show that ： automatic shift pressure regulating can be used to solve the disadvantages of the current disk brake control better.
