卷积型加权残值法求解梁的动力学问题
THE CALCULATION FOR THE DYNAMIC PROBLEM OF A BEAM BY METHOD OF CONVOLUTION-TYPE WEIGHED RESIDUALS
【摘要】 利用卷积型加权残值法推导出Gurtin变分原理。并应用卷积型加权残值法计算了简支梁的振动、冲击问题,算例表明此方法是成功的.
【Abstract】 In this paper, Gurtin variational princi- ples are derived by the method of convolution-type weighted residuals. The method of convolution- type weighted residuals is applied to analyze the vi- bration and shock problems of a simply supported beam. The results of the examples show that the method is valid.
