| 摘 要： | 运用有限元理论建立了火箭滑橇高速滑轨系统的橇-轨耦合动态分析模型,计算了不同轨道平顺度条件下橇-轨动态效应,得到了橇车在轨道上运行姿态的变化规律,分析了轨道平顺度对橇-轨动态效应的影响.研究表明:橇车在轨道上运行时产生偏航摆动、升降、俯仰和绕橇车质心滚转;随着轨道偏差的增大,橇车平均冲击加速度和平均冲击力近似呈线性增长... |

| Abstract: | Based on finite element theory,sled-track dynamic model of high-speed slide-rail of rocket seld system was established,and dynamic interactions of sled-track under different rail regularity conditions were calculated.The variety law of attitude of sled train running on track was obtained.The effect of track regularity on sled-track dynamic interaction was analyzed.The results show that:the sled train running on the track can cause yaw,heaving,pitching and rolling around its inertia centre.The average impact... |
