Tire Design and Testing Simplified with Use of Capacitance Pressure Mapping System

摘要

Until recently, precise measurement of low contact pressures in real time while the event occurs was difficult to accomplish. An electronic sensor system using capacitance is now available to accurately measure and capture low tactile pressure information in tire related applications. The heart of the system is a thin, durable, flexible, high resolution and highly reusable electronic sensor element which is adaptable to the application being measured. The element contains sensing points or pixels capable of being as close as 04" (1mm) apart and can capture data readings at up to 500 times per second. Therefore, the sensor is enormously helpful in monitoring precise force disbursement between any tow contacting or mating surfaces. Pressure ranges can be selected for optimum viewing, with choice of printable screen displays in color or black and white as well as in varied formats for dynamic measurement.
