Computer Aided Analysis of Dynamic Torque of Door System

In this paper, CAMD (Computer Aided Multibody Dynamics) method is used to find the dynamic torque for a given elevator door system. The conventional expressions for the torque is considered first and the proposition for the new approach is discussed. The computational algorithms for the dynamic torque analysis of a given door system is proposed using inverse dynamics which is actively applied in the field of robotics, and CAMD method which is widely used in Vehicle dynamics. The possibility of the proposed method is examined for the application of real door systems.
