摘　　要：单自由度体系计算体系自振频率是结构力学课程中动力计算部分很重要的内容,本文阐述了用柔度系数和刚度系数分别计算梁结构的体系自振频率时的差异,并探讨了产生这种差异的原因。Calculation of natural frequency in single degree freedom system is a very important part of the dynamic calculation in the structural mechanics course. These paper discuses the differences in the natural frequency calculation resulting from different methods, either by calculating flexibility coefficients or by calculating stiffness coefficient. It also discusses the reasons for this difference.

关 键 词：单自由度体系 柔度系数 刚度系数 自振频率
