Abstract

This thesis addresses the fundamental weakness of the current CAD capabilities and develops a new CAD system with optimization capability. A computer-aided mechanism design system is developed for general problems of optimal kinematic synthesis of planar four-bar mechanisms. The new system is made as user-friendly as possible and it is unique in that it combines Graphics capability, general Analysis capabilities, and Optimization capability into one system. Related background theory in IMP, optimization and optimal synthesis of mechanisms are discussed. The problems and methods in developing the new system are addressed. New routines and modifications made to the original systems are explained in detail. The design applications, user instructions and program listings are provided. The limitation of the system and problems for further development are also put forward in the thesis.
