碩士 === 國立清華大學 === 動力機械學系 === 81 === A new method of designing straight-line mechanisms based on curvature theory and instantaneous invariants is discussed. Previously it has been shown that all of the potential solutions to a given synthesis problem may be represented in a solution plane. One precision position with the direction of the coupler point and the length of straight line have been used as constraints for generating this plane which can be subdivided into mechanism types, then the feasible regions on the plane can be found. Characteristics such as branch defect must be also considered. The techniques for automatic synthesis have been implemented in an interactive computer program. A numerical example of applying the program to an actual straight- line problem is provided to illustrate the procedure in detail.
