摘　　要：垂直发射飞行器竖立在发射台上时,往往要受到地面风的作用,这将引起飞行器的振动响应,并影响到发射前的准备工作。将垂直发射飞行器简化为圆柱形悬臂梁,利用随机振动理论,建立了飞行器任意风向的响应。并对CZ—2、土星IB气动弹性模型在地面风荷载下的动态响应进行工程计算,与试验结果有良好的一致性。Vertical launch vehicles are almost always exposed for grand winds before taking off. As a result, oscillation of the vehicle will occur and it may affect the preparative before launch. The vertical launch vehicle as a cylindrical cantilever beam and builds the response to wind with any direction for the vehicle using random vibrationtheory are simplified. The dynamic responses of aeroelastic models based on CZ-2 and Saturn IB under ground wind load are calculated. The results are obtained in good agreement with the measured responses.
