摘要:
针对波尔共振仪的共振相位差测量，提出了同步跟随相位测量方法.设计了一套跟随振动系统摆盘的受控刻度盘系统，刻度盘以振动系统的摆盘的最大转速为转动速度，刻度盘上的任意一点在水平方向的投影与振动系统摆盘的摆动为等效的振动.完整的同步跟随相位测量系统由振动系统摆盘测量系统、受控刻度盘系统和驱动同轴盘测量系统组成.同步跟随刻度盘根据振动系统摆盘测量系统所采集的数据取代摆盘，并与驱动同轴盘同轴，当同步跟随的刻度盘与振动系统摆盘达到同步时，在共振发生时同步跟随的刻度盘和驱动同轴盘也几乎同步转动，所以驱动同轴盘零指针总指向同步跟随的刻度盘一个相位值，驱动同轴盘与刻度盘之间给出相位差.同步跟随相位测量方法将不受环境因素影响，便于在不同照明条件下布置多台实验仪器.
Abstract:
A synchronous phase follow method was presented,which is different from the stroboscopic method. A rotating disk was used to synchronously track a wobble plate that substituted for the vibration system.A set of controlled dial\|disc system with following the swing disk of vibration system was designed,the maximum speed of the wobble plate in vibration system was seen as the rotational speed of dial\|disc,the vibration of horizontal direction projection of a point in the dial\|disc was also seen as the swing of the wobble plate in the vibration system.The complete synchronization phase measuring system consists of the wobble plate measuring system,the controlled dial\|disc system and the driven coaxial disk measurement system.Synchronous tracking dial\|disc was coaxial to the driven coaxial disk,and obtained the data from the wobble plate measuring system.When the dial\|disc synchronized the wobble plate of the vibration system,the dial\|disc synchronized the driven coaxial disk almost at the same time with the occurrence of resonance.Then,the zero pointer of the driving coaxial disk always pointed to a phase value of the synchronous tracking dial\|disc,and the resonance phase difference was got from the comparison between the driven coaxial disk and the dial\|disc.The method will not be affected by environmental factors,and is very convenient to arrange the multiple test instruments under different lighting conditions.
