Interpolation Approximation Design of Pin-Jointed Four-Bar Linkages with Corresponding Angular Displacements of Grounded Links
Interpolation approximation is used in the design of Pin-jointed Four-bar Linkages with corresponding angular displacements of grounded links to realize approximately a given function. First Four-bar linkage position equations with parameters to be determined are established；then the paper sets up the relationships between given function and approximation function；finally it chooses Chebychev interpolation points to determine the approximation function. Angular error analysis is also conducted. A design example is given for reference in the end.
