目的观察在超重环境下由于动头或座舱姿态变化所引起的定向知觉 ,探讨在地面用高级空间定向障碍模拟器模拟超重错觉的可行性。方法用模拟器匀速旋转产生 1 .6G的超重环境 ,1 2名男性战斗机飞行员分别于俯仰平面内抬头前后和滚转平面内座舱倾斜姿态改变前后报告其定向知觉。结果在俯仰平面 ,被试者完成抬头动作后 ,体会到座舱发生了 63.8°± 48.3°的上仰 ;在滚转平面 ,当座舱向左倾斜 2 0°后 ,被试者体会到座舱向左发生了 48.6°± 39.4°的倾斜。结论虽然在模拟器上有较强的Coriolis效应存在 ,大多数被试者均体验到了超重错觉 ,在地面用模拟器模拟超重错觉是可行的。
Objective To observe the directional perception caused by the change of head or cockpit attitude in overweight environment and to explore the feasibility of simulating the overweight and illusion by using the advanced space orientation obstacle simulator on the ground. Methods Simultaneously rotating with a simulator to produce a super-heavy environment of 1.6G, 12 male fighter pilots reported their directional perception before and after lifting their heads in the pitch plane and tilting attitude of the cockpit in the rolling plane respectively. Results In the pitch plane, the subjects realized the elevation of 63.8 ° ± 48.3 ° in the cockpit after completing the head-up movement. In the rolling plane, when the cockpit tilted to the left by 20 °, the subjects realized that the cockpit left A tilt of 48.6 ° ± 39.4 ° occurred. Conclusions Although the Coriolis effect exists on the simulator, most of the subjects experience overweight and illusion. It is feasible to simulate overweight and illusion on the ground using simulator.
