This paper describes the results of the fundamental study of rising motion analysis considering the flexibility. The authors construct a finite element model with linear beam elements and contact elements with nonlinear property for axial stiffness for the study of the geometrical nonlinear analysis. First, to obtain the equilibrium sitting state for gravity, the forces that linearly increase from 0 to weight by 100 steps are applied to the human body. After that, three pin-connected parts are rotated by extension bars to generate the rising motion. In this manipulation, the mode of motion at each part is manually selected from among the tension, stop and compression. This manipulation is visually selected and done by using the operation panel, which is constructed by the object oriented program language Visual Basic. By these procedures, the reasonable equilibrium sitting state, leaning forward state and standing up state are obtained. So we can verify the fundamental function of this model.
