摘要
文中利用了两种对非规则边界参数区域进行拟合的方法,对同向双螺杆挤出机四面体间隙进行了拟合,并建立了一种曲面拟合误差测量的新方法;应用此法,从度量曲面的整体贴近程度方面对拟合曲面进行了误差分析。
Two methods were applied to fit surfaces of the tetrahedral gap of an intermeshing co-rotating twin-screw extruder. The surfaces are irregular border＇s parameter domain. And a new method was proposed to measure the error and was applied to measure the error between the fitting surfaces.
