STUDY ON VIBRATIONAL MODE ANALYSIS OF AVU CYLINDRICAL SHELL

摘要

The finite element analysis and research on the vibrational mode of a certain AUV with the analytic method are expatiated. Based on the basic equations of thin shells theory, this paper analyses and sets up the cylindrical shell vibrational mathematical model, and validated the correctness of the model by ANSYS. The method presented is effective in analyse and dynamical design of AUV weaken vibration and low noise structure.
