| 摘 要： | 用样条有限元法分析了杆的接触冲击动力响应问题，建立了计算格式，并用算例说明该方法的有效性。该方法充分利用了样条函数的解析和数值双重性及连续性强的优点来构造杆的位移函数，因此可推广应用于分析结构在冲击荷载下的动力响应问题。

| Abstract: | Based on spline function method,the spline finite element formulation for the contact impact problems is proposed.In order to get the formulation,the B3 spline function is used to distribute the contact problem,and numerical examples are analyzed to show the effectiveness of the method.Because the spline function has double characteristics including analytical and numerical,and good continuity and high correctness,a little unknown number and high efficiency,the spline functions are used to set the displacement of the bar,and the whole structure equations are constructed directly.It is convenient to analyze dynamic response of the structure by using the method. |
