摘　　要：抗坠毁座椅是提高直升机安全性的重要措施。本文首次研究了应用于直升机抗坠毁座椅的智能气囊缓冲器,论述了智能气囊缓冲器在直升机上应用的可行性。智能气囊采用了智能材料与结构新概念设计,可提高缓冲器的性能。与其它缓冲器比较,智能气囊能主动控制冲击过载,可使坠撞事故中乘员受到的冲击过载更为平缓,提高缓冲保护的有效性。初步实验结果证实智能气囊缓冲器的原理是正确的。Anti-crash seat is an important measure enhancing for the sa fe ty of heli-copter.In this paper the author firs tly advanced the intelligent a irbag-cushioning device for helicopter' s anti-crash seat,and described the a pplication feasibility.The perfo rmance of the cushioning device is improved by using the intelligent material of th e airbag combined with the advanced design concept of s tructure.Compared with other cushi oning device,the intelligent airbag can control and s moothen the crash acceleration therefore the passenger will be more affectively protected i n case of crash accident.The princip le of the intelligent airbag cushioning device is proved c orrect by preliminary exp erimental result.
