摘　　要：含牵制释放系统的运载火箭释放过程中贮箱箱底将承受较大的过载。论文提出了三种释放过程中贮箱箱底承受总载荷的计算方法,以及载荷在箱底分布形式的计算方法,并对1ms线性释放的某运载火箭助推器贮箱箱底载荷及其分布形式进行了分析。所提出的方法为我国新一代运载火箭的分析与设计提供了技术支持。Very large overloading will.be carried by the container bottom of the launch vehicle with Hold-Down and Release（HDR） system in HDR process. Three types of calculating method are put forward for the container bottom＇s general load in HDR process. A type of calculating method does so for distributing form of the container bottom＇s load. Container bottom＇s general load and its distributing form are analyzed for a launch vehicle＇s booster in 1ms linear release mode. The presented methods will provide technology support for the analysis and design of our new generation launch vehicle.
