摘　　要：为了研究战斗机座舱在高温环境下的操作工效,采用环境模拟方法,在40℃和45℃下,对10名男性受试者进行握力、感知、灵活性、反应以及智力的工效测试,并将数据与综合热应激指数(CIHS)对比。通过不同温度下受试者各项目平均值的比较显示,CIHS分别在45 min和20 min时超过热应激安全线;握力分别下降了12%和3.2%;最小感知力分别增大了2.89倍和4.36倍;手指灵活性受到的影响较小;反应在初始阶段加快,随时间的延长而变慢,智力测试时间缩短,但失误率上升。高温环境下,最小感知受到的影响最大,握力次之,反应和灵活性的变化较小,智力没有下降,反而上升。10 male subjects participated in the environmental simulation study to evaluate the operation ergonomics at high-temperature in the cockpit.Grip strength,perception,dexterity,reaction and intelligence were measured respectively during the tests at 40℃ and 45℃,simulating the high-temperatures in a simulation cockpit chamber.Then the data obtained were compared to the combined index of heat stress（CIHS）.The average values of each item of the subjects＇ performance at the two different temperatures are compared.The results indicated that CIHS exceeded the heat stress safety line after 45min at 40℃,grip strength decreased by 12%,and perception increased by 2.89 times.In contrast,at 45℃,CIHS exceeded the safety line after 20min,grip strength decreased by 3.2%,and perception increased by 4.36 times.However,Finger dexterity was less affected. Reaction ability was first accelerated,and then slowed down.The error rate in the intelligence test increased to a greater extent.At the high temperatures,the minimum perception was the most affected,followed by grip strength,reaction and finger dexterity were less affected,while the intelligence did not decline,but rise.
