| Abstract: | The structure objection was found by analyzing problems in using of the fan. The frame and blade was redesigned to improve the inherence frequency of the fan. Then the test was done and the result showed that the redesigned fan had a reasonable structure and could meet the demand. The optimized design method was helpful to the design of the similar production. |
