| 中文摘要: |
| 针对一种用于分体式整形装置的对合机构，课题组为了减小其运动过程中由于惯性力产生的机械振动，将装置运动简化为曲柄滑块运动。根据对合机构运动的初始和结束状态，利用几何关系建立约束方程使得2滑块运动状态基本一致，再利用解析法对平面机构进行运动学分析，在SolidWorks运动算例中得到滑块的运动特性，并选取2个角度参数验证了数值计算与实际运动相吻合；利用MATLAB优化工具，以曲柄杆长为设计变量，曲柄摆动角度以及压力角大小为约束条件，滑块加速度峰值最小为设计目标，进行优化。结果表明：当曲柄长为100.46 mm时，滑块加速度最大可降低45.33%。 |

| Based on a coupling mechanism for a split type shaping device, aiming to reduce the mechanical vibration caused by inertial force during the process of movement. Research group simplified the movement of device to movement of crank slider, and established constraint equations to make sure two sliders always in an approximately same state. Then, research group used analytical method to analyse kinematics characteristics of coupling mechanism and verifying the whole movement through simulation in SolidWorks. Last, with crank lever length as the design variable, crank swing angle and pressure angle as the constraint conditions, and the minimum slider acceleration peak as the design goal,using optimization tool in MATLAB optimized.The results show that when the crank length is 100.46 mm, the maximum acceleration of slider can be reduced by 45.33%. |
