摘要
本文应用机械系统仿真软件ADAMS对平面连杆机构（曲柄摇杆机构、双曲柄机构）进行运动输出精度分析与仿真。
通过VisualBasic软件编程求出满足条件的曲柄连杆机构和双曲柄机构各铰接点的坐标，在ADAMS中建立理想平面连杆机构虚拟样机和含运动副间隙的平面连杆机构虚拟样机。进行了考虑杆长变化和考虑铰链间间隙同时存在时候对平面连杆机构运动精度的影响。通过设置间隙铰链连接碰撞力进行运动仿真，比较真实的反应了含间隙运动副对机构运动精度的影响。

关键词 平面连杆机构 曲柄摇杆机构 双曲柄机构 ADAMS 铰链间隙 精度分析
Abstract
Based on Multi-Body Dynamic theory and Virtual Prototyping Technology, the motion precision analysis an simulation of the planar bar linkage(four-bar linkage) have been studied in this paper by using mechanical system simulation software ADAMS.
By using Visual Basic program software to get the coordinate of the coupler point .Virtual prototypes of the ideal planar bar linkage are established in the ADAMS software. Prototypes with joint clearance are established, too. And both prototypes are parameterized. Considering the length error or joint clearance or both of them, the motion behaviors of the planar bar linkage in kinematics and dynamics have been simulated. the impacts of bar error and joint clearance on the precision of the motion path of planar bar linkages have been analyzed, , the impact forces of the joint pairs in motion have been computed in this paper and the motion behaviors of the planar bar linkages with joint clearance are realistically simulated in dynamics.

Keywords planar bar linkages virtual prototype multi-body dynamics ADAMS joint clearance precision simulation.
