摘要
本文对镍盘转动影响因素进行了理论与实验的探究,制作了一个可以绕轴自由转动的镍盘装置。研究的内容主要有磁铁个数、磁铁离轴心的距离、加热区域到轴心距离和轴心到磁铁的连线与轴心到加热区域连线的夹角对镍盘转动规律的影响;通过对受热镍盘的受力分析给出了居里点发动机转动模型,并优化设计了研究方案。研究结果表明,当磁场强度增大时,镍盘转动周期变小;当磁铁与轴心的距离增大时,镍盘转动周期变大;当加热区域到轴心距离越短时,镍盘转动周期越长;当轴心到磁铁连线与轴心到加热区域连线的夹角越大时(0°<θ≤90°),镍盘转动周期越短。截至目前,该项研究在国内外鲜见报道。
In this paper,the factors affecting the rotation of nickel plate are studied theoretically and experimentally,and a nickel disc device which can rotate freely around an axis is made.The main contents of this study include the number of magnets,the distance between the magnet and the spindle center,the distance between the heating zone and the spindle center,and the angle of the line from the spindle center to the magnet and the line from the heating zone to the spindle center.The rotational model of the Curie point engine is given through the force analysis of the heated nickel disk,and the research scheme is optimized.The results showed that the rotation period decreased when the magnetic field intensity increased,the angle(0°<θ≤90°)between axis to magnet and axis to heating area increased,and the distance between the heating zone and the spindle center increased,but it increased when the distance between the magnet and the spindle center increased.The similar study has been less reported worldwide till now.
