曲柄滑块急回机构的设计研究

Research on the Design of Slider-Crank Quick-Return Mechanism

给定行程速比系数K时,如何设计出最大压力角为最小的曲柄滑块机构,或者给定许用压力角时,如何设计出行程速比系数K为最大的曲柄滑块机构?这是设计者希望解决的优化设计问题。本文用黄金分割法,编制出简单的QBA SIC程序,可以迅速解决上述问题。

How to design the slider-crank mechanism with minimum max pressure angle given ratio K？ Or how to design the slider-crank mechanism with maximal stroke - speed ratio K when the allowable pressure angle is given？ These are the points that designers want to find out solution with optimal design. In this paper the author works out a simple program in QBASIC with the golden section method, with which the above problems can be solved quickly.
