Research on the fastening scheme of screw group of electronic components based on finite element simulation

Abstract

In order to explore the fastening scheme of screw sets in electronic components, the workbench of ANSYS finite element analysis software is utilized to establish a simulation model for the process analysis of screw sets. Using the thread preload as the constraint, Workbench is utilized to explore the effects of different tightening sequences and the number of tightening times on the maximum stress of the screws. The simulation results show that 1-3-4-2 can make the screws bear uniformly and the maximum stress is the smallest; the increase in the number of screwing times tends to decrease and then increase the maximum stress of the screws, which can be used by the finite element analysis software to provide a reference for the actual fastening situation.
