Research on Contacts Contact Pressure Sensor Calibration Techniques Based on Pendulum-Typed Metal Ball Impact Method
The PVDF piezoelectric film is used to be a contact pressure sensor, it is very difficult to carry on the static calibration.In order to find the relationship between the output voltage of a contact pressure sensor and the actual contact pressure on the contact, this paper introduces a quasi static calibration technique based on pendulum-typed metal ball impact method.This method is simple, reliable, easy to operate, and the least square method are used to fit the data.A calibration bench was designed and a contact pressure sensor dynamic calibration system was set up.The calibration was completed in the laboratory, and the calibration curve of the output voltage of a contact pressure sensor and the actual contact pressure on the contact was obtained, and the conclusion is that the relation of the two is linear.The conclusion provides a valuable reference for further research on the relationship between instant contact pressure, the contact resistance, vibration and other parameters.
