Influence Analysis of Vertical Arm on the Ground-wind Loads of a Launch Vehicle with the Three-Horizontal Test Launch Mode
为提高运载火箭地面风载条件对地面风场较大的发射场的适应性、降低运载火箭设计载荷、减轻火箭结构质量、提高运载效率,针对三平测发模式的特点,开展起竖臂对运载火箭地面风载的影响分析.采用基于广义位移和广义载荷的运载火箭地面风载计算方法,根据起竖臂的结构特点,量化分析竖臂刚度、支承油缸刚度、抱箍数量及位置因素对运载火箭地面风载的影响程度.起竖臂刚度、抱箍数量和位置对运载火箭地面风载影响较大,提高起竖臂刚度可使根部弯矩降低24.8%,增加Ⅰ级箱间段抱箍可使…查看全部>>
In response to the characteristics of the three-horizontal test launch mode,an influence analysis of vertical arm on the ground-wind loads of a launch vehicle is carried out so as to improve the adaptability of the ground-wind load condition of the launch vehicle to its launch site under large ground-wind loads,reduce the design load and structural weight of the launch vehicle,and improve the launch efficiency.The ground-wind load of the launch vehicle is ca…查看全部>>
