为在缺乏可靠性数据的初级阶段提高煤矿坑道钻机的可靠性,运用模糊理论建立了系统可靠性模糊预测的模型。通过卡瓦的可靠性指标估算出夹持器的可靠性指标,再以夹持器的可靠性指标估算整机的可靠性指标,从而为整机的可靠性预测提供了方法,为设计者提供了有效的反馈信息。
In order to improve the reliability of mine tunnel boring machine in the initial stage of lack of reliability data, a fuzzy reliability prediction model of system reliability is established. The reliability index of the gripper is estimated through the reliability index of the slip, and then the reliability index of the whole machine is estimated by the reliability index of the gripper, thereby providing a method for the reliability prediction of the whole machine for the designer Effective feedback information.
