Abstract
Dynamics of a moving body restrained in a 3D trajectory is investigated. The equation of motion of the moving body is derived by using differential algebraic equations (DAE)method. By using this equation, the time history simulation analysis is performed. Also, the kinematics and vibratical experiment have been performed using the actual roller coaster in site. The accelerations in simulation are compared to those in experiment. Both show a good coincidence qualitatively.
