摘要
通过剖析啮合同向双螺杆四面体间隙的几何性状，建立了四面体间隙体积的数学模型，准确地求出了四面体间隙的体积，并用三次样条函数近似，使得模型得以简化，为设计和深入研究双螺杆挤出机提供了有力的工具。
By studying the shape and geometrical properties of tetrahedral gap in the intermeshing co rotating twin screw, a mathematical model to precisely calculate the volume of tetrahedral gap has been developed in this paper, which was simplified by approximation using a third order spline function, served as a powerful tool for designing and deepening research into twin screw.
