| Abstract: |
| The acoustic radiation character is not considered in traditionally structural dynamic design optimization.With advanced environment quality required by the people,more and more attention is paid to reducing acoustic level,so the design and control of structures considering the minimum of acoustic level is a subject of more active research.Based on the finite element method for structural dynamical equation and boundary element method for acoustic equation,the acoustic radiation optimization model built in this paper is solved with sequential quadratic programming.The above theory and algorithm is carried on JIFEX system.Numerical results show that acoustic radiation could be reduced effectively using the method presented in this paper. |
