摘要
通过均匀细杆纵振动理论,模拟分析和实验测量研究了部分弯曲细杆的纵振动固有频率。实验结果表明,理论分析得出的纵向振动固有频率与实验结果相符,且通过实验和模态分析可以得到弯曲细杆有很好的传振作用。
The longitudinal natural frequency of bending rod was studied by long Longitudinal theory, model analysis and experiment measurement. The results showed that the measured frequency agreed with the ealeulate frequency. Moreover,transfering vibration function of bending metallic rod was very good by experiment and model analysis.
