一种用于非充气轮胎垂向力监测的PVDF传感器布置方法
By establishing a piezoelectric charge model for PVDF sensors and a strain transfer model for spoke-PVDF sensors, the optimal placement of sensors for monitoring the vertical force of non-pneumatic tires was determined. This solved the problem of a lack of theoretical basis for sensor placement and improved the consistency and sensitivity of the monitoring signals.

AI Technical Summary
Existing technologies have failed to effectively establish a strain transfer model between PVDF sensors and non-pneumatic tires, resulting in a lack of theoretical basis for determining sensor position, difficulty in extracting signal features, and a lack of theoretical support for the relationship between sensor output and force state, making it difficult to ensure the consistency of monitoring signals.
By establishing a piezoelectric charge model for the PVDF sensor, a strain transfer model for the spoke-PVDF sensor, and a triaxial strain relationship, and combining multiphysics simulation software Comsol and Simulink, the electric displacement distribution in the sensor arrangement area is calculated. The optimal radial arrangement position of the sensor is determined using the sliding window discrete integration method, and the mounting surface is selected by maximizing the charge gradient and linearity.
The optimal radial arrangement of PVDF sensors was achieved, which improved the sensitivity and consistency of vertical force monitoring signals, simplified the signal processing flow, avoided transmissibility errors, and adapted to different load frequency variations.
