| Abstract: | The modeling and simulation of thermal deformation of the linear motor are studied to improve the motion precision of the uniaxial linear motor. The factors that influence the uniaxial linear motor thermal deformation are analyzed, and the one dimensional dynamic heat transfer mathematical model is constructed. The heat transfer characteristics of linear motor mechanism are analyzed by using ANSYS. And then, one dimensional mathematical model for thermal deformation is established. Finally, the thermal deformation data varying with time is calculated based on simulation data. This paper provides not only the method for uniaxial linear motor thermal deformation modeling, but also the heat transfer characteristics of the linear motor. |
