电风扇动力学模型

Kinetic Models of a Fan

电风扇的动力学模型是我们身边真实的物理问题,也是大学物理课程教学案例,建立了电风扇的3种动力学模型——线性功率模型、线性力矩模型和广义驰豫模型,实验表明广义驰豫模型拟合结果最佳。从研究方法、概念规律和素质培养三个方面对此做了探析。

Dynamic models of a fan are real physical problem around us, and also good college physics courses teaching cases. This paper approaches three aspects of research methods, concepts of law and the quality of training. This paper established three kinetic models of a fan -- liner power model, liner torque model and generalized relaxation model. Experiments show that the generalized relaxation model fitting results are the best.
