Thermal characteristic is one of the most important mechanical properties of materials. The paper studied the thermal deformation characteristics of mechanical parts by using the microscopic numerical simulation and macroscopic experiment. The paper took a set of 3D aluminum crystal models as the objects of study and got the thermal deformation data by the Molecular statics method. Meanwhile, we also carried out series of macroscopic thermal deformation experiments of aluminum sample. The consistency of microscopic simulation and macroscopic experiment results demonstrate that the thermal deformation of mechanical part is obviously affected by its shape and structure parameters, which should not be ignored in precision machinery engineering. The further study in this area will guide the optimization design of mechanical part parameters and improve the accuracy of precision machinery and instrument. |
