多功能向心力测量转台应用控制变量法,实现对向心力规律的全面定量探究;也可用于“弯道受力分析、滚桶脱水、柱形墙内的水平圆周运动、法拉第电磁感应定律”等典型物理问题的教学.装置采用变频电源驱动同步电动机的方式来实现匀速转动,调速和计速一步到位,无需电磁或光电门测速装置;利用手持电子秤代替弹簧秤或拉力传感器,从而免去了DIS实验系统;使用了推力球轴承,用转台代替横梁,无需配重,稳定且更具承载性.
Multifunctional centripetal force measurement turntable application of control variables, to achieve a comprehensive quantitative study of the laws of centripetal force; can also be used for “bending force analysis, barrel dehydration, cylindrical horizontal circular motion within the column, Faraday’s law of electromagnetic induction” and so on Typical physical problems of teaching devices using variable frequency power drive synchronous motor way to achieve uniform rotation, speed and speed in one step, without electromagnetic or photoelectric door speed measuring device; the use of handheld electronic scales instead of spring balance or tension sensor, thus eliminating the need DIS experimental system; the use of thrust ball bearings, turntable instead of beams, without counterweight, stable and more load-bearing.
