摘　　要：为提高掘进机的截割效率和运行可靠性,降低截割能耗、载荷波动率及截割产尘量,以纵轴式掘进机截齿个数、截线间距、截割转速、摆动速度以及周向分布角为设计变量,采用掘进机的截割比能耗、载荷波动率、截割单位产尘量最小为优化目标,将可靠性灵敏度融入不完全概率信息的截割头可靠性鲁棒设计中,利用随机摄动法和Edgeworth级数方法对掘进机截割头参数进行可靠性优化,采用混合粒子群算法进行模拟可靠性运算,研究结果表明:该方法解决了不完全概率信息的掘进机截割头鲁棒设计问题,在不降低掘进机截割效率和可靠性条件下,截割头的载荷波动率下降31.8%和比能耗降低4.0%,单位产尘量降低14.2%.In order to improve reliability and boring machine cutting efficiency, reduce energy consumption and load fluctuation rate and the amount of dust production, this paper built the least optimize target of load volatility and amount of dust production, and energy consumption by boring machine cutter number, cut-off line spacing, speed, swing speed and angle of the circumferential distribution. The probability of reliability sensitivity is not fully integrated into the cutting head of information reliability optimization design, Then it use of random perturbation Edgeworth series method and multi-objective fuzzy reliability boring machine parameter optimization. The optimization results showed that the method solve the incomplete information on the probability of tunneling machine cutting head design problem, the cutting head of the load fluctuation rate has decreased 87.6% and energy consumption decreased 24.2%, and amount of dust production decreased 24.1%.
