| Abstract: | t Five young male subjects(18-23 yrs. )were exposed to +Cy stress and were tested for two dimensional tracking performance on a human centrifuge of 12 meter radius. Some physical parameters such as tracking error, output signal of side-arm controller and input signal of the compensatory tracking system and physiological parameters such as EEG and EMG were recorded. Methods of system indentification and statistics were used for data processing.It was found that subjects mean tracking error and controlling efficiency decrease and human operating dynamic parameters such as mean gain effective delay time and frequency of tracking motion are changed with increase of G value and brain load. Result of analysis showed that cause of decrease in human tracking ability may be related to arm biomechanic effect and changes of brain function under + Gy stress. |
