前言关于钢管矫直机的正确辊形曲线问题,全国许多研究者从不同的角度,以不同的方法进行了深入地研究,导出了各种不同的计算公式。这些公式参数不一,繁简各异。本文应用相对运动原理和曲面的包络理论,导出了辊形曲线的参数方程。本文给出的辊形曲线方程形式比较简单,而且方程中的参数几何意义明确。 Preface As to the correct roll curve of steel tube straightening machine, many researchers across the country have conducted in-depth studies with different methods from different perspectives and derived various calculation formulas. These formulas vary in parameters and vary in complexity. In this paper, the relative motion principle and surface envelope theory are used to derive the parametric equation of the roll curve. The form of the roll-shaped curve equation given in this paper is relatively simple, and the geometrical meaning of the parameters in the equation is clear.
