摘要向量式有限元是在向量力学基础上提出的一种新型数值方法，在分析结构大变形和复杂边界条件时具有很大优势。本文基于向量式有限元基本思想，借鉴结构试验中的力控制和位移控制方法，提出力-位移复合控制的模拟方法，对同一结构、同一分析过程可以分别考虑时间上的力-位移交替控制和空间上的力-位移混合控制，在此基础上可求解结构的大变形。数值算例验证了本文方法的可行性和有效性，拓展了向量式有限元的应用范围。

Abstract：Vector form intrinsic finite element (VFIFE) is a new numerical analytical method based on vector mechanics and point value description.This method has a great advantage in solving the problems of structural nonlinear discontinuity, such as large deformation, large displacement, fracture and collision, and the dynamic prediction of mechanism.According to the method of force control and displacement control in structural tests, a method of force-displacement compound control was put forward and an analytical model was established based on the VFIFE method in this paper.This compound control method includes an alternating force-displacement control method and a force-displacement mixed control method.On this basis, the large deformation of a structure was solved, and a numerical example was given to verify the proposed method.

Key words： vector form intrinsic finite element force control method Displacement control method nonlinear analysis large deformation.
