Abstract

In terms of the difficulty and high cost of the full-size sound-vibration environment test of the rocket fairing, the similarity criterion of the scaling model is established by the dimensional analysis method. The study shows the relationship between the internal sound field and acceleration within the scaling models as well as the original model, and the finite element method (FEM) simulation is carried out. The simulation results show that the sound pressure level at the field point of the scale model is basically the same as that of the original model, and the acceleration is proportional to the model scale, which is consistent with the result from dimension analysis. This method provides a theory evidence for the sound-vibration environment prediction and test of the rocket fairing.
