| 摘 要： | 本文对两端固定的弯曲薄板在其支承简谐运动激励下的振动特性问题进行了实验研究，重点考察了在不同的初始曲率下激振频率ω的变化对弯曲薄板振动响应形态的影响规律，实验表明，在某些频率段上弯曲薄板会发生多周期及混沌等复杂运动。

| Abstract: | An experimental study on the vibration of curved panel being bent cylindrically with fixed ends excited by the periodic motion of its supporting base in the direction of being normal to the panel span was made in this paper.The experimental system were analyzed by FFT and Time-Traces.Attention was concentrated on the effect of forcing frequency on the behavior of the system under the different initial curvatures of panel.It is found that chaotic motions may occur in some regions of forcing frequency. |
