Testing polymer rollers memory in the context of passenger lift car comfort

Abstract

The article presents the authors’ own studies on the application of polymer materials with different physical and chemical properties for vibro-insulation of lifting appliances. The studies were performed on a static test stand, which was made as part of works on the examined polymers, as well as on a dynamic test stand. We analyzed the effect of various polymer materials upon the phenomenon of susceptibility and possibility of returning to primary shape after the load disappears. We determined susceptibility characteristics for examined polyurethane materials. Study results are important from the point of view of improving the comfort and operation of lifting appliances.
