Lightweight design of elevator cage in shaft construction based on topology optimization
In this article,in order to improve the elevator cage's mechanical properties in shaft construction and ensure its weight reduction,the SolidWorks 3D software is used to model the cage;the topological examples are applied to explore the cage's structure;a method is proposed to deal with the topological optimization model;the treated model is imported into ANSYS for the static analysis;both the total deformation and the maximum stress under four limit conditions are calculated.It is verified that the cage's maximum stress is far less than the material's allowable stress,which ensures that the structural strength is reliable.In addition,efforts are made to explore the overall vibration frequency of both the construction elevator and the cage after optimiza-tion;then,the optimized cage's first six-order natural frequency is identified.The system natural frequency is compared with the cage's vibration frequency;then,the speed prone to resonance is worked out.The results show that after optimization,the cage with a more reasonable structural layout has desirable mechanical properties,meets the design requirement of lightweight,and a-voids the possibility of structural resonance.
