三层结构模型的内共振和组合共振
Internal and combinational resonances of a three-story structure
Experiments on internal and combinational resonances of a three-story structure are investigated. The frequency ratio between the first and the second modal of the structure is set near 1:3 by modal design. The internal resonance behaviors are found when the excitation frequency is near that of the first or second modal frequency. Meanwhile, several types of combinational resonances are found in this structure. These results made a foundation for future modification of the nonlinear vibration equipment.
