The equation of motion of the real adaptive truss having nodal offsets is formulated to discuss the influence of the nodal offset on its dynamic behavior. It is shown that the equations of motion of the ideal and real adaptive truss models can be formulated in the unified description by paying attention to the variables which express the state of the dynamic motion. Simulation studies and the calculated natural frequencies demonstrate the significant influence of the nodal offset on the dynamic behavior of the adaptive truss. It is also shown that the magnitude of the offset must be small enough in order to eliminate the influence. The nodal offset design problem is formulated based on the natural frequency criterion, and a case study shows a possible nodal offset design of the adaptive truss.
