Dynamics of an Elevator: 2-Dimensional Modeling and Simulation

Author: Simon R. Eugster

 

This thesis proposes on the example of an elevator a novel general way to merge a 1-dimensional continuous structural element in a non-smooth dynamical system. The procedure allows it to describe effects of material behavior, normal contacts and tangential contacts with Coulomb type friction. As a part of the procedure all used mechanical concepts and their mathematical foundations are introduced. A drum elevator is modeled and simulated with a 2-dimensional representation. The cable rope is considered as a deformable structural element, e.g. a limp elastic rope with no bending stiffness. The interaction between cable rope and drum is modeled as a hard frictional contact. As an example an elevator running up is simulated successfully.
