| Abstract: | The acoustic radiation of cylindrical shell that contains manufacturing geometric errors was simulated and computed by using Ansys and Sysnoise software,and the results were compared with the ones of perfect cylindrical shell.Checking the influence of the acoustic radiation caused by the various forms of geometric errors,the rule that the acoustic radiation increasing with the geometric errors was obtained. |
