机械振动与机械波多功能演示装置

Multi-functional demonstrator of mechanical vibrations and mechanical waves

根据振动和波动之间的联系和区别,通过真实的振源将"横波演示器"和"简谐振动图像演示仪"2个实验装置进行整合改进,研制出机械振动与机械波多功能演示装置.该装置可以同时演示机械振动和机械波教学中的多个关键实验,具有直观、形象、易于操作的优点,有助于学生更好地理解机械振动和机械波的概念,降低准确掌握二者联系与区别的教学难度.

According to the connection and difference between vibration and wave,them ulti-func-tional dem onstrator of mechanical vibrations and mechanical waves was developed by combining and im proving the transverse wave dem onstrator and sim ple harm onic vibration graph dem onstrator through a real vibration source.This device could dem onstrate several key experiments in the teaching of mechanical vibration and mechanical wave at the same time,which had the advantages ofintuition,visualization and easy operation,was helpfulto students to better understand the concepts of mechanical vibration and mechanical wave,and reduced the teaching difficulty in mastering accurately the connection and difference between them.
