| Abstract: | 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 400~1 200 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 1 000 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. |
