Stress analysis of lifting table using finite element method

Abstract

Lifting table has been designed and developed through the concept of Learning Factory (LF) at the University of Mostar. The idea for lifting table design has come from the local industry needs for a lifting platform that should lift a man and/or load at a certain height. For safety reasons, design is checked under the loading using a method of finite element analysis. The paper predicts and explains methodology for structural analysis used in presented case study. Results of FEM analysis are basis for making ways and guidelines to optimize current design in order to get optimal parameters for weight, stability, capacity, mobility and layout of the lifting table.

Design and Prototype Production of Scissor Lift Platform 25 Tons Capacity

“…Figure 3 shows the total deformation, Von-Mises stress analyses of the scissor platform, and the stresses acting on the bearing ear. The entire configuration of the platform truss is not considered a mechanism but a rigid structure in which the components at the contact points are related links [13]. The minimum yield stress value (235 MPa) of the structural material used as the maximum limit to define the stress state of the platform was taken.…”
