Dynamic Property Test and Simulation of Rocket

摘要：

Purpose For big slenderness ratio structure rocket, the bodys inherent dynamic character must be gained to calculate the flight intensity and stabilization. Method Using the equivalent mass method to simplify the body, the finite elements model is established and the structure modal is calculated. The bodys modal experiments are done using the modal identify technique. Result The bodys inherent character can be gained by the two methods, lower step modal distinction minor. Conclusion Using the equivalent mass method, high-accuracy natural vibration frequency is gained by means of simulation. The results can be used for the bodys flight intensity and stabilization calculation.
