Watt six-bar is one of planar six-bar mechanisms and is used widely. In this paper, the kinematic analysis of the mechanism is finished, and its outputs of displacement, velocity and acceleration are studied. In this paper, the six-bar used in an oil pumping machine is taken as example, through the ADAMS simulation, the curves of displacement, velocity and acceleration of the mechanism are obtained. The modal analysis of the rocker arm is completed in ANSYS, and it can provide a basis for its dynamic analysis.瓦特六连杆是应用很广泛的一种平面六连杆机构，通过对瓦特六连杆机构进行运动学分析，研究了其输出位移、速度、加速度变化规律。以瓦特六连杆机构在抽油机上的应用为研究对象，通过ADAMS仿真得到该机构的运动情况，同时应用ANSYS软件对摇臂构件进行了模态分析，为该机构的动力学研究提供了依据。
