节点力
The final finite-volume discretization equations are derived using the Hamilton principle. Meanwhile the global nodal force vector, mass matrix and tangent stiffness matrix of the cable are obtained.
再根据哈密顿原理导出了悬索大挠度振动的有限体积离散方程,推出了索的整体节点力向量、质量矩阵和切线刚度矩阵。
Equivalent additional stress method can be the same with integral method or combined method depending on the equivalent method of additional nodal force calculated.
等效附加应力法根据附加节点力计算方法的不同分别对应整体式和组合式方法。
