摘要
介绍可视化有限元系统VSES中采用的一种应力图生成方法。首先用扫描线转换填充算法判断各象素是否在单元内,根据单元类型用不同插值方法计算单元内各点应力,最后设置颜色函数,计算各模型中各象素点颜色。由颜色函数的不同设置,可得到应力云图和色带图,用轮廓线追踪法获得应力等值线。方法具有速度快、适应性强、显示效果好等特点。
A method of forming stress images which applied in VSES is introduced.The arithmetic of scanning line is firstly used to analysis whether a point belonged to a element ,and different techniques are applied to calculate the stress value of a gived point according to the type of element.Finally,some colour functions are setted and the colour values of pixels in elements are computed.Both stress nephogram and stress ribbon image are drawed through changing the colour functions.Stress isoline image is made by using the methoh of pursuing contour line.The application in a system VSES shows that the new method have some advantages such as high speed and good adaptability.
