This study is pointed to a computer table with five degree of freedom. The table position could be adjusted freely. The height of the tabletop also could be moved freely. The finite element analysis software ANSYS was used to analysis the strength and rigidity of the computer table. From the analysis results, it can be found that the strength and rigidity were fit in with the specification requirement with a safety factor of 1.20. From the modal analysis results, it also found that the stability of the computer was confirmed to the users.
