equivalent node force等效节点力
1.The distribution of local magnetic force is described with anequivalent node force,which is derived from an extended application of virtual work principle to FEM node.该法将虚位移原理推广应用于有限单元的节点,从而得到用以描述局部电磁力分布的等效节点力。
2.Therefore, on the basis of finite element method (FEM) and local virtual work method, a mathematical model was built according to the principle of virtual work equivalent, so as to calculate the magnetic force density inside medium or magnetic stress on the interface of different mediums after theequivalent node forces were solved.为此,在有限元分析方法(finite element method,FEM)和局部虚位移法的基础上,按虚功等效的原则建立由等效节点力进一步计算介质内部电磁力密度和不同介质交界面处电磁应力的数学模型,进而推导了二维平行平面场条件下的具体计算公式。
3)equivalent node load等效节点荷载
1.Based on prestressing force s mechanism,it was proposed thatequivalent node load was used to simulate its spatial effect during tensing,and that degenerated solid element was employed to take prestressed.从预应力筋的实际作用机理出发,提出在预应力张拉阶段用等效节点荷载来模拟预应力对结构的作用;而在预应力管道灌浆后,将预应力筋作为结构的一部分,用实体退化单元进行结构分析,并用两算例对本文的方法进行了验证。
