What is A Study on the Lightweight Design of Lift Structure by Composite Materials about?

The purpose of this study is to reduce the weight of elevator components in order to save energy and apply the findings to the new drive-type elevator system. Structural design has been carried out for two lightweight elevator models in which the damped aluminum laminate (DAL) and carbon fiber reinforced plastics (CFRP) are utilized for the elevator walls, respectively. The structural designs of the new elevator walls are based on the bending stiffness of the existing steel walls. The aluminum elevator model is designed to exhibit a bending stiffness similar to that of the existing steel elevator, while the CFRP model is designed to possess 20% of the existing wall bending stiffness considering that the tensile strength in the fiber direction is about nine times higher than that of the existing structural steel material. DAL and CFRP are applied to the elevator walls, respectively, and aluminum sandwich structures are applied to the ceiling and platform of two kinds of lightweight elevator models. It has been ascertained that the aluminum elevator model is about 40% lighter than the existing steel elevator, and the CFRP elevator model is about 50% lighter than the existing elevator
