【摘要】 本文以双曲柄—曲柄滑块组合机构为例,对平面串联机构的组合规律进行了研究,讨论了串接参数的作用,从理论上阐明了机构串接组合的过程。在此基础上,着重探讨了从减少设计变量数、简化目标函数和缩小设计变量取值范围等方面简化这类组合机构尺寸最优综合的具体方法,还提出了一种把尺寸可调机构的设计转化成定尺寸机构设计的方法。最后给出计算实例。更多还原

【Abstract】 This paper deals with the optimum size synthesis of the complex mechanism with adjusting link, which is the planar double-crank mechanism connected in series with the slider-crank mechanism. A slider moving at approximately uniform speed in its working stroke is the chief design aim. A simplified optimizition design of the complex mechanism is presented, and some concrete methods studied. This simplification is based on the combination law of complex mechanism with less design variables, simplified objective function, and reduced domains in which design variables are got. In addition, a method of changing the design of a complex mechanism with adjusting link into the design of a complex mechanism without adjusting link, is present. Finally, an example is given in this paper.更多还原
