| 摘 要： | 粘弹性动力人工边界在结构-地基动力相互作用问题的有限元分析中已得到了广泛的应用,但对于规模较大的复杂计算模型而言,粘弹性动力人工边界的施加存在着前处理工作量浩繁、施加精度不高等问题.为此,基于粘弹性动力人工边界理论及ABAQUS软件平台,提出了粘弹性动力人工边界精确自动施加方法,编制了相关程序并进行了验证.算例将本文方法和通常的近似施加方法进行了对比分析,结果表明,近似施加方法会引起较大计算误差,本文所提出方法的施加简便性、施加精度均优于通常的近似施加方法. |

| Abstract: | The viscoelastic dynamic artificial boundary is widely applied in the dynamic analysis of structure- soil interaction; but the work of preprocessing is time-consuming and lack of precision for the complex numer- ical simulation. In this paper, the method of accurate auto- application of viscoelastic dynamic artificial bound- ary is presented based on the theory of viscoelastic dynamic artificial boundary and FEM software ABAQUS; and the corresponding program is developed and verified. The comparative analysis of the method mentioned above and the approximate method usually used is completed through a numerical example. The results show that the approximate method usually used may arise obvious calculation error; and the method of accurate auto-application of viscoelastic dynamic artificial boundary is convenient for application and has a higher precision. |
