Abstract The uncertainties arising from the fabrication and operation of mechanisms, specifically the four-bar linkage, significantly affect the expected performance of the mechanism. To accommodate uncertainties during the dimensional synthesis of the four-bar linkage, the desired coupler curve response is described by any number of precision point elements and trajectory elements, where each element is specified with an allowable error. A design description which accounts for bounded uncertainties is termed an appropriate design. An appropriate synthesis method is developed to synthesize the entire set of appropriate design solutions corresponding to the desired response. This method is able to completely explore the continuous design space and each synthesized appropriate design guarantees that the resulting four-bar linkage has a corresponding coupler point which lies inside each precision point response element, and a corresponding set of continuous coupler points which remain inside the trajectory response elements from start to finish.

四连杆机构的适当合成

摘要 机构，特别是四连杆机构的制造和操作所产生的不确定性，显着影响了机构的预期性能。为了适应四连杆机构尺寸合成过程中的不确定性，所需的耦合器曲线响应由任意数量的精确点元素和轨迹元素描述，其中每个元素都指定了一个允许误差。考虑到有界不确定性的设计描述被称为适当的设计。开发了一种适当的综合方法来综合与所需响应相对应的整套适当的设计解决方案。
