直升机座舱显示器周边键的工效学设计对于改善直升机操控性能有重要作用,在振动环境下其工效学特性的研究是该领域研究的薄弱环节.本研究在研制的直升机座舱实验平台上,设计了振动环境下直升机座舱显示器周边键的工效学实验.通过分析实验数据发现:按键反应时受按键方位和大小影响,无振动时,按键大小为10 mm即可;主振为23 Hz,振幅为人体稍感振动时,按键大小应增加25%以上,即13 mm,按键间隔以10 mm为宜;振动造成错误率上升和反应时延长,应控制在适当范围.

Ergonomics optimization design of keys around screen in helicopter cockpit is meaningful to the improvement of operating performance, but the research on its ergonomics characteristics in a vibration environment is a weak link. In this article, we take a new method to investigate this problem with a simulation platform. Through data analyses, some results are summed up as follows. The response time is affected by key size and its position. That the key size is 10 mm is preferable without vibration. And that it is 13 mm, or 25% bigger, in other words, is preferable with the vibration of 23 Hz which can be felt slightly by human body. Under vibration, it is appropriate that the interval between keys is 10 mm. The increase of mistakes and response time caused by vibration must be under suitable control. The result of this research is of some reference value to the ergonomics design and improvements of helicopter manipulating performance.
