摘要
本文对考虑阻尼的杆在轴向冲击作用下的动力屈曲性能进行了理论分析,通过采用Rayleigh阻尼理论,对动力屈曲控制方程解耦得一变系数微分方程,在分析方程解的基础上,探讨了阻尼对轴向冲击杆动力屈曲性能的影响,揭示了含阻尼结构的动力屈曲现象,定义了动力屈曲准则及确定阻尼杆临界载荷参数的方法.
The dynamic buckling of a column with damping under acal impact is studied in this paper. Based on the analysing solution of the equation. the dynamic buckling phenomenon of damping structure is investigated, the effect of damping on the column's buckling properties is discussed and, a dynamic buckling criterion and the method to determine the critical load parameters are also proposed.
