目的 观察飞行员短臂离心机不同转速暴露时前庭性错觉诱发效果及前庭自主神经反应情况,寻求利用短臂离心机进行前庭性错觉地面模拟训练时的合适转速. 方法 90名健康歼击机飞行员根据不同离心机转速(21、30、37 r/min)分为3组,每组30人.参考电动转椅的前庭性错觉模拟训练方案,采用适合短臂离心机运行特点的前庭性错觉诱发方法,在SAC-Ⅲ型短臂离心机上进行反旋转错觉及科里奥利错觉模拟.每组仅进行1个转速下的错觉模拟.对比不同转速下飞行员错觉诱发情况及前庭自主神经反应情况. 结果 ①离心机不同转速时飞行员反旋转错觉、科里奥利翻转错觉(包括头右旋及左旋时)及科里奥利旋转错觉(包括头前倾和回靠时)的诱发率差异均有统计学意义(X2 ＝6.477～20.000,P＜0.01或P＜0.05).21 r/min暴露时的诱发率低于30 r/min和37 r/min暴露时(x2＝0.073～0.351,P＞0.05).②3种转速下,离心机反旋转错觉形态表现相同,但错觉强度随离心机转速加快而增强.科里奥利翻转错觉形态表现稳定,3种转速下其表现分布差异无统计学意义((x2＝0.090、0.056,P＞0.05).科里奥利旋转错觉形态表现较为多样,3种转速下头前倾时错觉形态表现分布差异无统计学意义(X2＝1.810,P＞0.05);头回靠时错觉发生例数较少,未行统计学处理.③3种转速下前庭自主神经反应评分分值随转速增加而增高,且差异有统计学意义(F＝ 15.058,P＜0.01);37 r/min暴露时的分值明显高于21 r/min和30 r/min暴露时(P＜0.01或P＜0.05);30 r/min与21 r/min暴露时的分值差异无统计学意义(P＞0.05). 结论 臂长2 m的短臂离心机上以30 r/min暴露时,飞行员前庭性错觉的诱发率较高,且前庭自主神经反应较轻,此转速用于飞行人员前庭性错觉的地面模拟训练较为合适.

Objective To observe the effects and characteristics of vestibular illusions and vestibular autonomic reactions induced by short arm centrifuge exposure,and to search the appropriate rotation speed of short arm centrifuge for vestibular illusion simulation training on the ground.Methods Ninety healthy pilots were divided into 3 groups by the rotation speed of 21,30 and 37 r/min that generated by SAC-Ⅲ short arm centrifuge.By referencing the vestibular illusions simulation training on electric rotating chair,they were exposure to the simulation of counter-rotatory illusion and Coriolis illusion.Vestibular illusions and vestibular autonomic reactions were compared.Results ①When the speed was 21 r/min,the induced rates of the counter-rotatory illusion,Coriolis tumbling illusion (including head turn to right and to left) and Coriolis somatogyral illusion (including head pitched up and down) were lower than the induced rates under the speed of 30 r/min and 37 r/min (X2＝6.477 20.000,P＜0.01 or P＜0.05).And when the speed was 30 r/min and 37 r/min,the induced rates showed no significant difference (x2 ＝0.073-0.351,P＞0.05).②The expressions and characteristics of the centrifuge evoked counter-rotatory illusion were approximately the same under three different rotation speeds,while the illusion strength was enhanced with the speed increase.The expressions and characteristics of the Coriolis tumbling illusion induced by different speed showed no significant difference (X2 ＝0.090,0.056,P＞0.05).And the expressions of the Coriolis somatogyral illusions were multiform.Under three different speeds,the Coriolis somatogyral illusions showed no significant difference when the pilot's head pitched down (X2 ＝ 1.810,P＞0.05).The case of Coriolis somatogyral illusions was very rare when pilot's head pitched up and the result was not taken into account.③The scores of vestibular autonomic reaction were increased with the rotation speed increase,and showed significant difference (F＝ 15.058,P＜0.01).When the speed was 37 r/min,the score of vestibular autonomic reaction was significantly higher than the scores of 21 r/min and 30 r/min (P＜0.01 or P＜0.05),and there was no significant difference between the scores of 21 r/min and 30 r/min (P＞0.05).Conclusions When the speed of centrifuge was 30 r/m in,the induced rate of the vestibular illusions was the highest and the vestibular autonomic reaction was mild.For the 2 m arm centrifuge,the 30 r/min rotation was appropriate for pilots' vestibular illusion simulation training on the ground.
