| Abstract: | At present, enclosure noise control has been the emphasis and difficulty. In this paper, comprehensive theoretical and experimental study have been carried out on GB1236-85 acoustics cavity. A twenty-node isoparametric element is developed. The designed CAD software can automatically generate data file and compute frequency. Experiments show good agreements between theoretical and measured results. |
