| Abstract: | The vibration mode of a free-free thin-walled cylindrical shell with end ring is reported. The calcalatian was made by MSC/PAL2 and MSC/NASTRAN. The experiments was processed by a Data Auto Sample and Process system named DASP. The calculation resualts are compatible with test data for first 30 medes. |
