A Dynamical Analysis of Folder Type of Industrial Automatic Door

Abstract:

This paper deals with a formulation and analysis of dynamic mechanism for the folder type of automatic door extensively used in industrial plants. A nonlinear equation of motion is derived in terms of folding angle to estimate driving forces. An operating time needed to open the door and corresponding velocities are controlled for the purpose of design. The stiffness of torsional spring is also investigated when the automatic door is closed to prevent the free falling. This research includes a numerical experiment for the two-step folding automatic door which results from the analysis methodology for this multi-step folding mechanical system.
