风场作用下囊舱组合体相对姿态仿真研究

摘要
对于使用缓冲气囊的返回舱,着陆姿态是影响返回舱实现预期缓冲效果的重要因素。在降落伞-返回舱组合体的降落过程中,返回舱的着陆姿态经常不理想,而加入气囊后降落伞-返回舱-气囊组合体相对于降落伞-返回舱组合体来讲着陆姿态更易受扰动,此时对囊舱组合体运动姿态的研究十分必要。为了研究风场对囊舱组合体运动姿态的影响,文章以带有自吸式气囊的回收系统作为研究对象,采用Hyperwork及LS_DYNA软件,对基于流固耦合方法气囊充气状态及囊舱组合体风场作用下的运动特性进行了分析,计算了不同工况下囊舱组合体的相对姿态,分析了可能影响囊舱组合体相对姿态的因素。结果表明,气囊内压与风速会对囊舱组合体的相对姿态产生不同程度的影响:风速越大气囊摆角越大;增加气囊内压会降低气囊的摆角,提高气囊的稳定性。
The landing attitude of return capsule with cushioning airbag is the main factor which affects achieving the expected buffering effect. During the landing process of parachute and return capsule, the attitude of return capsule is often unsatisfactory. After the addition of the cushioning airbag, the attitude of capsule and cushioning airbag is more susceptible to disturbance. So it is necessary to study the attitude of capsule and cushioning airbag assembly. This paper mainly studies the influence of wind field on the attitude of capsule and airbag assembly among lots of disturbing factors, which is relative with the attitude of capsule and cushioning airbag assembly. In this paper, the recovery system with self-priming airbag was used as the research object, and the analysis of fluid structure interaction and airbag inflation state were carried out by using Hyper work and LS_DYNA. The relative attitude of capsule and cushioning airbag assembly under different working conditions were calculated and the factors could influence the attitude were analyzed. The simulation result suggests that the pressure in the airbag and the wind speed affect the attitude differently. The oscillation angle of the cushioning airbag will increase with the increase of wind speed. Increasing the pressure of airbag can reduce airbag swing angle and improve airbag stability.
