This work investigates the path synthesis of planar four-bar linkages using elliptical Fourier descriptors (EFDs). EFD is also a Fourier-based analysis method. Its Fourier coefficients of a coupler curve are separately obtained through Fourier expansion of the x and y components of the coupler curve rather than on a function. Compared to conventional Fourier descriptors, elliptical Fourier descriptors are better able to describe complex curves such as curves with cusp. A numerical atlas can be set up using Fourier coefficients derived from elliptical Fourier analysis. The optimization method can subsequently be applied to match the curve with the required one.Atlas | Elliptical Fourier descriptor | Four-bar linkages | Path synthesisconference paper10.1007/978-3-031-45709-8_202-s2.0-85176961875https://api.elsevier.com/content/abstract/scopus_id/85176961875
