A Design of Equidistant Curves Based on Scalene Fundamental Quadrilateral

Based on the forming principle and geometrical characteristics of equidistant curves,a design of equidistant curves of scalene fundamental quadrilateral under conditional circumstance is discussed.The effects that the equidistant curves varies with the changing of the form and the side’s length of a of fundamental quadrilateral is also studied.Besides,the design principles of equidistant curves are stated and the graphing methods of profile curve are proved as well.Hence the scope of designing and the characteristics of scalene fundamental quadrilateral are confirmed.What’s more,the approaches and methods on equidistant curves design of the profile connection of mechanical transmission are further extended.
