摘　　要：针对机构结构形式最紧凑的主要设计目标,利用ADAMS软件构造共轭凸轮-杆组合机构关键点参数坐标,完成参数化实体建模。经灵敏度分析寻找对机构紧凑设计结果影响最大的关联变量组,在坐标几何约束条件下对变量组进行试验设计仿真解算。根据CP杆端运动轨迹特征对仿真曲线分类,其结果表明右凸轮传动杆、摆杆长度对机构紧凑性影响较大,运动轨迹形状在杆长不同时可能呈现不同特点且变化拐点之间不易通过数学函数描述;在设计目标的约束中还应考虑纵向速度在吸纸段的波动状况。Aiming to find the most compact conjugate cams link combination mechanism, ADAMS had been used to form key points coordinates function and established a parometerized model The most object-result-related design variables group can be searched by sensitivity analysis technique. After run DOE（design of experiments ） test accordingly, link CP＇ s kinematic path can be categorized by simulation results of curve data, and it indecated that the right corn＇s connection link and pendulum rod had the most significant impact on mechanism＇s compactness, but influnced endpoint＇s velosity at X axis slightly. A conclusion can be drown that motion path will either present different pattern when change the length of link or hard to be decribed as a function. Concideration on the variation of velosity at y axis should be included in the constraints of desien object.
