Innovative approach and method of conjugate-contour construction for Roots rotor
Published 2025-05-01“…Therefore, an innovative approach and method are proposed which is suitable not only for common known but also for current unknown conjugate-contour curves.MethodsThe concepts of engagement-distance as length and engagement-angle as direction of conjugate-vector from the pitch-point to the engagement-point was proposed, the intrinsic logic relation of engagement-distance and engagement-angle was summarized, and then the innovative approaches and methods of conjugate-contour construction were proposed.ResultsThe results show that different conjugate-vector functions uniquely determine different conjugate-contour shapes; different conjugate-contour shapes directly determine different output performance; the innovation of output performance is equivalent to the innovation of conjugate-contour; the engagement-angle is equal to the arc cosine function of the first derivative of engagement-distance to the rotation-angle of pitch-circle; the innovation of the conjugate-contour is equivalent to the innovation of the engagement-distance function. …”
