| Abstract: | This study analyzes the dynamic property of beam structure with random parameter under the bending vibration. A new method of analyzing the effect of randomicity of structure parameter on the dynamic property of the bending beam is advanced. The numerical feature of dynamic property of the beam with random parameter under the bending vibration is developed based on the probability analysis. As a result, the influencing factors on the dynamic property are also revealed in the study. |
