Design of the UHF RFID passive tag vibration measurement instrument

According to the anti-vibration performance test requirements to the UHF RFID passive tag in the application of civil aviation luggage transport, the paper designs a vibration measurement instrument for UHF RFID passive tag. A vibration test scheme is designed based on non-resonance single-axis inertial vibration principle, which builds the mathematical model and vibration equation. Thereafter, a software ADAMS is applied to simulate the vibration performance, and the effects of motor speed, eccentric quality and spring stiffness coefficient are analyzed to provide the basis for the further manufacturing. Finally, a prototype is realized, and a vibration performance test based on piezoelectric accelerometer is proposed to obtain the performance parameters. The test shows that the parameters including vibration frequency and the maximum peak to peak vibration displacement satisfy the design requirements.
