摘　　要：平面四杆机构作为一种常用的急回机构,在工程中得到广泛的应用。为了提高急回四杆机构的设计精度和设计效率,通过对传统解析法的剖析,再结合几何原理,提出了一种较简单的四杆机构解析方程式的建立方法。利用MATLAB软件,可以快速的求解方程组,通过改变方程组中参数的值,可以较快而又精确地设计出所需的急回四杆机构。As a common quick return mechanism, the plane - four - bar mechanism is widely used in engineering. In order to improve the design accuracy and efficiency of the qus proposed through the analysis of the traditional analick return four - bar mechanism, a relatively simple method to establish a analytic equations of the quick - four - bar mechanism iytical method and combining the geometric principle. By using the MATLAB software, the equations can be solved quickly. By changing the parameters value of equations, the quick -return four -bar mechanism can be designed quickly and accurately.
