摘　　要：为提高单轴直线电机的运动精度,对该类直线电机热变形建模与仿真进行了研究。分析了影响单轴直线电机热变形的因素,在直线电机托板上建立了一维动态热传导数学模型,并借助ANSYS对该类直线电机机构的热传递进行了仿真分析,并建立了一维热变形数学模型,依据仿真数据计算出热变形随时间变化数据。不仅提供了单轴直线电机热变形的建模方法,且表明了直线电机热传递的特征,有利于直线电机热变形补偿的进一步研究。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 mod- eling, but also the heat transfer characteristics of the linear motor.
