Abstract
In this work, the structure of the linear elevator prototype had been investigated numerically using finite element method. The linear motor structure parameters analyzed using Maxwell ANSYS. The time-stepping method depending on Maxwell equations be applied for analyzing and optimizing the magnetic and force characteristics. While the elevator structure parameters were analyzed using ANSYS workbench based on the principle of virtual work. The frame considered as clamped- clamped beam, and the base of the car considered as thin plate with small deflection. The analysis done with maximum applied load of 360 N at 1.5 safety factor. The results show the distribution of the magnetic lines, the flux density values plus the leakage flux inside the slots. The maximum Von-Mises stress and the deformations of the frame and plate at maximum load are acceptable and present save design. In which the maximum deflection of the thin plate not exceed (thickness/5) at maximum design load.
Highlights
The maximum von- Mises stress and the deformation of elevator frame be acceptable. The maximum deformation of car base plate be acceptable, which less than h/5 that satisfy the design boundary condition of ω<h/5. The maximum stress and deformation that occur on the plate and frame of elevator present save design as compared with the mechanical properties of the materials’ selection.
