Abstract: | A method of solution of design variables was presented using the vibration reliability model of the magnifying factor in response to the forced vibration, based on analysis of the conventional vibration reliability model. The fan blade vibration reliability was evaluated by use of its test data, which provides basis for modifying the design and eliminating the vibration. |
