By applying resistance strain gauge measuring method and the finite element method simulation technology,the strain rule of rack mounted server chassis under full load state and deformation feature were measured and analyed. According to research results,large strain occurs on the front of chassis because of heavy hard disks.The maximum equivalent strain is located on the front bending parts of the chassis base bottom and the maximum deformation is located on the front middle parts of the chassis base.Maximum e-quivalent strain and deformation meet the design requirements.The result error of simulation and test is less than 10%,so the simulation results are reliable.
