不考虑轴向运动，采用两端简支的模型以阶次跟踪方法实验研究铜带的强迫共振和主参数共振。从谱阵图中易发现强迫共振频率等于横向激励频率，主参数共振频率为铜带张力波动频率的1/2，并且两种共振振幅峰值频率均大于铜带的固有频率，这与理论分析相符，为后续研究工作提供了实验依据。

The experimental research using order tracking for forced resonance and principalparametric resonance of the cop-per belt without axial movement is made based on a model with both ends simply supported .The figures show that the frequen-cy of forced resonance is equal to the tension fluctuation frequency .The frequency of principal parametric resonance is half of the the longitudinal excitation frequency .And the frequencys of maximum amplitude are greater than the natural frequencys of belt.This is similar to the theoretical analysis, also provide some experimental basis for further research work.
