摘要：

连杆运动不干涉是八连杆机械压力机杆系设计的重要约束条件。拉延速度和加速度直接影响八杆机械压力机性能。提出了八连杆机械压力机杆系不干涉条件的判据，并以不干涉条件、拉延速度和加速度作为惩罚项，使用复合形法对具有13个优化参数的八连杆机械压力机杆系进行了优化，通过优化结果可得到性能较优、满足运动不干涉条件的八连杆压力机杆系。最后以实例说明八连杆机械压力机杆系的优化设计过程，并通过三维软件验证了该结果的可行性。

Noninterference movement is a key constraint condition for the eight-links mechanical press design. The performance of the eight-links mechanical press is influenced by the drawing velocity and acceleration directly. A criterion of the noninterference movement was proposed. With the noninterference movement condition, drawing velocity and acceleration as penalty terms, 13 parameters of the eight-links mechanical press were optimized based on complex method. From the optimization result, a better performance of the eight-links mechanical press linkages with noninterference movement was obtained. In the end, an illustration of eight-links mechanical press optimization design was given. The feasibility was verified by using 3D software.
