摘要
通过梁和板的模态分析 ,对无单元法中权函数的参数进行了讨论并优化 ;进一步计算了受突加荷载作用的简支梁以及具有初位移的简支方板的动力响应 .
The parameters study of the weight functions of Element Free Method has been carried out to determine their best values by the modal analysis of the beams and plates. Then the responses of these structures under dynamic excitation have been analyzed. The examples include simply supported beams subjected to sudden excitations and simply supported plates subjected to initial displacements. Numerical examples show that this method has high accuracy in vibration analysis.
