摘　　要：针对超声速下非对称翼型火箭橇运动稳定性分析与控制难题,采用模态分析优化了非对称结构的振动频率特性,并对翼型火箭橇在非对称载荷下,400~1 200 m/s速度工况下的橇轨耦合动态响应特性进行分析。对翼面的不同气动下压力、不同靴轨间隙对橇体振动的影响进行对比分析,并对橇体关键部件材料进行分析,最终得到1 000 Hz内滑靴和翼面的动态载荷预示值与实测值的偏差不大于15%。该分析方法可为非对称翼型结构设计及橇体参数的选取提供数据支撑,保证火箭橇在轨安全运行,为非对称翼型火箭橇试验平台的构建提供了技术支撑。In order to solve the problem of stability analysis and control of asymmetric airfoil rocket sled under supersonic motion,the vibration frequency characteristics of asymmetric structure are optimized by using modal analysis,and the coupling dynamic response characteristics of airfoil rocket sled under asymmetric load at speeds of 400~1200 m/s are analyzed.The influence of different aerodynamic down pressure and shoe rail clearance on the vibration of skid body is compared and analyzed,and the material of key components of skid body is analyzed.Finally,the deviation between the predicted dynamic load value and the measured value in 1000 Hz is less than 15%.This analysis method can provide data support for the design of asymmetric airfoil structure,ensure the safe operation of the rocket sled in orbit,and provide technical support for the construction of the asymmetric airfoil rocket sled test platform.
