弹性介质中杆的动力稳定性研究

RESEARCH ON THE DYNAMIC STABILITY OF BARS IN ELASTIC MEDIUM

  • 摘要: 本文通过对弹性介质中杆在轴向动力荷载作用的分析,探讨了阻尼力对杆动力稳定性的影响,并导出了杆端具有不同支承条件下杆的动力分析计算式,可供实际工程应用参考。

     

    Abstract: In this paper,the dynamic performance of bars in elastic medium under axial dynamic load is studied.The formulas of dynamic analysis for straight bars under various sup-porting conditions are deduced.It is hoped that these formulas may provide some references for practical engineering.
