摘要
以三次Ｂ样条函数作为位移函数，利用有限元方法推导了梁单元的运动微分方程及系统运动微分方程，并以一弹性四连杆机构为例进行弹性动力分析，分析结果与实验结果吻合较好。
In this paper, the differential equations of beam elements are derived out with finite element method treating displacement function as triple B Spline function. An example of an elastic fourbar link mechanism is presented and the elastic dynamic analysis is practised, the analytical results are in good agreement with experimental results.
