| Abstract: | A mechanism for performing path synthesis is designed to guide one point on a moving rigid body such that it passes through a specified sequence of points on a path. The relationship between the number of the tasks, unknown variables and equations are discussed. A method for performing path synthesis of four-bar adjustable mechanisms for two alternate tasks is proposed based on BP neural network. A network is trained and all solutions are obtained. The method presented in this thesis can avoid tedious symbol derivation and reduce greatly computing work as compared with analytical approach. The errors between desired points and actual points are very small, and the path synthesis mechanism has higher accuracy. |
