摘　　要：采用"三垂"发射模式的运载火箭通过活动发射平台以垂直状态从技术区到发射区完成转场,活动发射平台通过轨道式行走装置实现行走功能。通过建立活动发射平台动力学模型,对活动发射平台在轨道上运行的动力学特性进行仿真,研究轨道垂向不平顺度对转场过程的动力学特性影响,为发射平台行走系统的动力学设计提供参考。The launch vehicle adopting"three-vertical"launch mode completes transition from technical area to launch area in a vertical state through the movable launch platform which realizes walking function through track walking device.By establishing dynamic model of the movable launch platform,dynamic characteristics of the movable launch platform running on the track are simulated,and dynamic characteristics influence of vertical irregularity of the track on the transition process is studied,which provides a reference for the dynamic design of walking system of launch platform.
