Design of Contact Pressure Measurement System for Brush Probe

The brush is an important component of the electrical slip ring.The contact pressure of the brush probe is the interaction force between the brush probe and the slip ring when the slip ring deforms the brush probe.The contact pressure of the brush probe is minimal and can be effected by many factors,but it is directly related to the technical performance and working life of the electrical slip ring.According to the characteristics of brush,this paper detailedly studied the measurement methods and techniques of the contact pressure of brush probe,and designed a contact pressure measurement system for the brush probe.The application shows that the contact pressure of the brush probe is automatically and precisely measured.
