| 摘 要： | 探讨初弯曲对杆件动力性能的影响问题，采用弹性稳定理论分析杆有初弯曲和初偏心时，对杆件动力稳定性的影响。实例表明，随着杆件初弯曲的增大，其杆件振幅值随之成比例增大，其杆件动力稳定性也随之降低。根据分析结果，提出了实际工程中减小或防止杆件初始缺陷的具体措施，可供实际工程应用时参考。

| Abstract: | The problem of the initial bend affecting the dynamic properties of a rod is dealt with here Based on the elastical theory of stability, a rods dynamic reaction in stability to an initial bend and eccentricity is analysed An example shows that, as the increase of an initial bend, the rods amplitude of vibration gets up and dynamic stability declines in proportion According to the analysis, some measures against the initial defects are proposed for rods These measures can be referred in practical fields of engineering |

| Keywords: | initial bending of rod dynamic stability amplitude |
