平面连杆机构再现轨迹的可靠性优化设计

Reliable optimal design of planar four—bar path generator

针对一般的平面连杆机构再现轨迹优化设计中一些不足之处,本文认为设计过程中应当同时考虑制造过程中公差给机构输出偏差带来的影响,在一般优化设计方法的基础上,本文运用可靠性设计的原理,建立了连杆机构可靠性优化设计的数学模型,为连杆机构再现轨迹的设计,提供了一个新的,更加合理的算法。

To improve the ordinary mathematical model of the optimal design of a planar four-bar path generator, it is pointed out that the effects of manufacturing tolerances and clearances should be considered during the design. On the basis of ordinary optimal design, the mathematical model for considering the principle of reliability design is set up in this paper. A new rational method of design is provided for the design of planar four—bar path generator.
