简谐振动图像演示器使用单色和双色发光二极管模拟简谐振动图像及其生成过程。它有以下特点:(1)能同时演示物体振动过程、参考圆及其振动图像3条曲线;(2)可演示物体振动周期的改变,快振和慢振自动切换。既能模拟谐振子连续的快速振动,以形成完整的视觉图像,又能模拟慢速振动,以反映从谐振子振动到参考圆映射而形成简谐振动图像的过程;(3)性价比高,演示操作方便,物理内涵丰富。
Harmonic Vibration Image Demonstrator Monochromatic and two-color light-emitting diodes are used to simulate harmonic vibration images and their generation. It has the following characteristics: (1) can simultaneously demonstrate the object vibration process, the reference circle and its vibration image 3 curves; (2) can demonstrate the object vibration cycle changes, fast vibration and slow vibration automatic switching. Which can not only simulate the continuous rapid vibration of the harmonic oscillator to form a complete visual image but also simulate the slow vibration to reflect the process of forming the harmonic vibration image from the vibration of the resonator to the reference circle; (3) Easy to operate, rich in physical connotation.
