汽车轮胎断面几何轮廓的计算机实现

应用轮胎平衡内轮廓基本公式，计算与选取确定的轮胎外轮廓参数。通过编程实现了轮胎断面几何轮廓的计算机生成。与实际轮胎断面轮廓对比表明，该程序计算准确、可靠，可视性好，可用于轮胎断面几何轮廓的自动生成。同时，计算了轮胎结构参数（如轮胎外直径、断面宽等）的改变对轮胎断面轮廓的影响，为轮胎设计提供了参考。

ComputerActualization of the Section Geometry Contour of Pneumatic Tire

The basic formulae of tire equilibrium inside contour and the parameters of tire outside contour ascertained by means of calculation and selection are applied to realize the computer creating of the tire geometry contour by computer program in this paper. The calculation results of this program are accurate.reliable and good visualization comparied with real tire contour, which can be applied to automatically generate the geometry contour of various tire and supply convenience for the research of the tire temperature filed afterwards. At the same time, Key words calculation is also done to analyze the relation between tire structural parameters (namely tire outside diameter.section width etc.) and the section contour of a tire, which provides the references to design tire.
