基于示波器的陀螺进动实验设计

Experimental Design of Gyroscope Precession Based on Oscilloscope

通过理论推导得出了在有摩擦力的情况下陀螺进动时的一般规律,发现其进动角速度和自传角速度的乘积为一定值,此定值与陀螺的转动惯量有关。通过设计实验对比了陀螺转动惯量的理论值和实验数值,两者的相对误差为0.68%,一方面说明理论分析的正确性,另一方面证明该实验设计合理。

It is found that the product of the precession angular velocity and the self-propagating angular velocity is a certain value,which is related to the inertia of the gyroscope.The setting experiment verifies the correctness of the theory,and compares the theoretical value with the experimental value through the design experiment.The relative error between the experimental value and the theoretical value is 0.68%.On the one hand,it shows that the theoretical analysis is correct,and on the other hand,it indicates that our experimental design is reasonable.
