抄録

As moving bodies on a complicated 3 dimensional trajectory, we take roller coaster as a model. Equations of its motion and conditions of constraints are set up for using the differential algebraic equation (DAE). Then, we propose the simulation method for the motion and vibration of multivehicles. In this paper, in addition to the previous report about the analysis of the constraint on s-z plane (s-axis is the direction of a length of trajectory which is tangential line for the projected trajectory on coordinate x-y), we analyze the constraint on s-u plane (u-axis is perpendicular to s-z plane).
