为了解铁路机车乘务员的疲劳状况,提高机车乘务人员驾驶适应性。于2004年12月至2005年1月选择某机务段的64名承担长运行交路提速列车(DF11G和SS9型机车)牵引任务的机车乘务员(长交路组)和同一线路运行且工作时间基本相同承担同一线路较短运行交路列车(DF11型机车)牵引任务的38名机车乘务员(短交路组),于出乘至退乘阶段测试临界闪光融合频率,出乘前和退乘后测试选择反应时,采用SIMH精神卫生自评表(SCL-90)和主观感觉调查表进行乘务员躯体化、强迫症状、抑郁症状、焦虑症状等职业紧张疲劳测试。结果显示,列车运行约4～7h乘务员闪光融合频率值下降,经过工间休息闪光融合频率有一定回升;退乘后选择反应时延长。提示乘务员值乘后出现一定程度的视觉疲劳或精神疲劳,退乘后均出现一定程度的神经疲劳,其健康效应应引起关注。
In order to understand the fatigue of railway locomotive flight attendants and improve locomotive crew adaptability. From December 2004 to January 2005, 64 locomotive attendants (long-crossing group) with long-range speeding train (DF11G and SS9 locomotive) towing tasks of a certain locomotive depot were selected and the same line operation and basic working hours 38 locomotive flight attendants (short-access group) who share the same traction task for the shorter-range operation train (DF11 locomotive) will be tested for the critical flash fusion frequency at exit to take-off phase, before and after take-off test Choose response, the use of SIMH mental health self-assessment form (SCL-90) and the subjective sensory questionnaire flight attendant somatization, obsessive-compulsive symptoms, depressive symptoms, anxiety and other occupational stress fatigue test. The results showed that the frequency of flash fusion frequency of flight attendants decreased about 4 ~ 7h after train operation, and the frequency of flash fusion had a certain rise after working off. It is suggested that there is a certain degree of visual fatigue or mental fatigue after the flight attendant multiplied by value, and a certain degree of nerve fatigue appears after the flight attendant. The health effect should be paid attention to.
