The main aim of this paper is to study the mathematical model of the single planar capacitance sensor by boundary element method. This numerical method is used to compute the solution of the partial differential equation with complex boundary conditions which was established as the model of the single planar capacitance sensor. We find out the relationship between dielectric constant of the measured object and the capacitance value of capacitance sensors. A single planar capacitance sensor, which was set its specific size, is taken as an example, numerical example shows that this method is effective. The method and results can be applied to the practice of engineering, such as measuring wood moisture content and soil moisture contant, etc.

Abstract Road traffic noise needs to be reduced, because traffic volume is increasing every year. The noise generated from a tire is becoming one of the dominant sources in the total traffic noise because the engine noise is constantly being reduced by the vehicle manufacturers. Although the acoustic intensity measurement technology has been enhanced by the recent developments in digital measurement techniques, repetitive measurements are necessary to find effective ways for noise control. Hence, a simulation method to predict generated noise is required to replace the time-consuming experiments. The boundary element method (BEM) is applied to predict the acoustic radiation caused by the vibration of a tire sidewall and a tire noise prediction system is developed. The BEM requires the geometry and the modal characteristics of a tire which are provided by an experiment or the finite element method (FEM). Since the finite element procedure is applied to the prediction of modal characteristics in a tire noise prediction system, the acoustic pressure can be predicted without any measurements. Furthermore, the acoustic contribution analysis obtained from the post-processing of the predicted results is very helpful to know where and how the design change affects the acoustic radiation. The predictability of this system is verified by measurements and the acoustic contribution analysis is applied to tire noise control.
