摘　　要：本文对机车乘务员每天工作的身体状态、疲劳程度提出了测试方法与评价模式。受试者３０人，在作业前、作业中、作业后、缺少睡眠、过量饮酒五种状态下对其平衡稳定安全可靠性进行测试。结果表明：作业前与作业后两者之间平衡稳定性度差异显著（ｐ＜０．０５）；缺少睡眠、过量饮酒与常态下比较差异显著（ｐ＜０．０５）。提示平衡稳定性度是用来快速检测机车乘务员安全可靠性的最新技术，并提出瞬时安全可靠性评价模式。The postural stability of 30 locomotive drivers was deeply researched with stabilometer and computer system.The testee stood on a force platform in each of 10 seconds' duration by analyzing the sum of frequency spectrum.Most drivers can maintain little sway well within limits during these trials.An estimation of center of human's gravity was measured by the force platform.The effect of working fatigue,drinking,lack of sleeping to the stabilization of body is very important.The results show significantly difference between pre work and other situations ( p <0.05).The authors proposes a safety reliability model for locomotive drivers.
