| Abstract |
In recent years, convenient and fashionable electronic products have entered our daily life. Among them, notebook computers have been widely accepted by the consumers. Hinges are one of the most important structures in a notebook computer. This research performs static analysis on a notebook computer and investigates the hinges’ behaviors as the computer screen is pull open. To ensure accurate simulation results, experiments were first conducted by repeatedly pulling open the screen of a notebook computer, and a force gauge was used to measure the pulling force at various opening angles. Then finite element software ANSYS was employed to simulate the pulling process of the notebook computer. With the averaged, measured force as a matching target, the finite element model was updated by tuning the friction coefficient between the shafts and the sockets of the hinges. Finally, based on the updated finite element model, modal analysis on the computer was performed to extract the natural frequencies and mode shapes. Harmonic response analysis was also carried out and both dynamic analyses were compared. This research may serve as a reference for designing hinge components and for accurate dynamic simulation of a notebook computer. |
