A study on the path synthesis of four bar linkage utilizing the method of rotation angle curve of links and on the evaluation of its multi solutions

本文利用连杆转角曲线法进行平面四杆轨迹综合，在对任意轨迹曲线的“无穷多点”实现了多解后，提出一种基于神经网络的多解排序方法，训练了一个前馈型神经网络在规定的条件下对多解进行评价、排序。在整个求解过程中实现了可视化，对设计中求得的机构还可以进行运动仿真，软件的界面设计合理，人机交互十分方便。

Carrying out the path synthesis of four bar linkage,utilizing the method of rotation angle curve of links and after realizing multi-solutions for the “infinite number of points”of arbitrary path curve this paper put forward a kind of method for the sequencing of multi-solutions based on neural network,and the evaluation and collation are made on multi-solutions by a trained forward feedback neural network under stipulated conditions.Visualization is realized in the whole course of seeking solutions and motion simulation can be conducted for the mechanism obtained in the design.The interface of software is rationally designed and it is very convenient for the communication between user and computer.
