The Assessment of Stress Analysis for a Notebook's Hinge Stopper Using the FEM Method

Abstract

Computer Aided Engineering (CAE) software is a vital analytical tool which is often adopted for product design. Engineers can obtain related design information for stress, strain, displacement, fatigue, and longevity of products via a CAE simulation. In order to improve product reliability, analysis of a products structure using CAE is compulsory. The purpose of this research is to implement CAE analysis on a laptops hinge. A 3-D model of the laptops hinge was first established by Pro/Engineer software and then transferred onto ANSYS/Workbench software. Moreover, all boundary conditions, connections, materials, and mesh property were set into an ANSYS program. Subsequently, the calculation of kinetic behavior for the hinge structure and maximum stress and stress allocation were performed by the ANSYS. In order to verify the correctness of the parameter settings on ANSYS/Workbench software, a products breaking test was conducted. A comparison between the experimental data and the theoretical data of the ANSYS was also carried out. Consequently, the deviation between the analyzed data and the real testing data is within 5%. Therefore, the analytical methods established above can provide a quick and efficient design for the structural strength of a hinge stopper.
