摘要
本文对轴向砰击载荷作用下杆的动力响应与屈曲问题进行了探讨。通过采用一种奇异摄动方法,求解了轴向砰击杆的动力响应与屈曲控制方程,在此基础上,分析其横向弯曲运动规律和动力屈曲现象,同时讨论了轴向砰击杆的动力失稳判据。最后,采用本文发展的理论计算了一个实例,计算结果与已有的试验结果之间有着较好的一致性。
The dynamic response and buckling of columns under axial slamming loads are investigated. The governing equation of. axiallyslammed columns is solved by singular perturbation technique. The lateral flexural motion and the dynamic buckling phenomenon of axially-slammed columns are analysed and a criterion for estimating critical buckling condition is proposed. The calculation shows to be in good agreement with the experimental results.
