Analysis of Planar Mechanisms Based on Symbolic Pattern Matching of Independent

Based on a problem decomposition strategy and a symbolic kinematic loop pattern matching technique, a new method for planar mechanism kinematic analysis has been uncovered. Since this approach directly applies an analytical, closed form solu-tion methodology to the planar mechanism kinematics problem, a number of signifi-cant advantages over other solution methods have been observed. Firstly, when ap-plicable, this new approach requires significantly less cpu time as compared with traditional numerical methods, making timely mechanism animation feasible. Secondly, the new approach eliminates the effect of computer truncation error, thereby eliminating numerical approximation errors. Finally, it can be used to search for initial positions of planar mechanisms with specified dimensions, thereby enabling automatic mechanism sketching
