【摘要】 为了实现计算机辅助设计和辅助制造双作用式旋板泵定子过渡曲线,本文试提出过渡曲线的一种数字模型,用来取代目前常用的极座标过渡曲线方程。利用这一数学模型便于分析、此较和评价各种过渡曲线的特性;扩大了过渡曲线的设计范围;有利于编写通用的计算机程序,为进一步实现过渡曲线的最佳设计创造了条件。更多还原

【Abstract】 For purpose of the computer-aided design and computer-aided manufacture of the transition curve of the dual-purpose vane pump cam ring,a mathematical model of the transition curve is proposed instead of the commonly-used transition contour equation in polar coordinates. The characteristics of different contours can be analyzed, compared and evaluated by means of the mathematical model. The model is advantageous to compiling a generally applicable computer program and favourable for optimum design of the transition contour.更多还原
