Development of a PVDF-based Rubber-Tread Deformation Sensing System for Understanding Wheel/Ground Interactions
In this paper,we present the development of a rubber-tread deformation sensing system that provides the critical information for understanding wheel/ground interactions.Polyvinylidene fluoride(PVDF)-based micro-sensor is designed and fabricated to embed inside the rubber tread or on the inner tread surface to measure the rubber-tread deformation.We discuss two different sensor placement locations inside the wheel.Analytical models of the PVDF-based sensing system are presented to capture the wheel/ground contact information and interaction characteristics.The sensed deformation measurements are integrated with the on-board control system through a wireless data transmission module.Some preliminary experimental results on a mobile robot are also presented to show the feasibility of the proposed sensing techniques.The proposed deformation sensing system can be further formed a distributed deformation sensor-array system to provide more complete information for understanding wheel/ground interactions.
