equivalent spring meaning in Chinese

等价弹簧

Soil springs are used around the pipe including vertical , lateral and axial soil springs to consider the interaction between the pipeline and the surrounding soil . the pipe segment near fault that usually suffers large deformation is modeled with a plastic shell element in order to consider the effect of local buckling and section deformation . to reduce the calculating time of the whole model , an equivalent spring proposed by the author is applied at two ends of the shell model
为了解决现有的壳单元方法需要大量计算机时的缺点，本论文首次从理论上把离断层较远管土之间相对变形较小的管子直线段部分的变形等效为一个非线性弹簧，将此等效边界引入到有限元模型中，使得模型中的壳单元部分主要用来分析我们所感兴趣的在断层附近发生大变形的管段，从而达到节约计算时间的目的。
