摘要:
在SolidWorks环境下构建了一种适用于自动化冲压生产线的5自由度串联机器人,并对机器人工作时上下料运动过程进行了详细描述。同时,针对自动上下料运动过程,运用数学模型进行理论分析,采用D-H法建立第2种机器人坐标系,列出运动学参数、关节变量和齐次变换矩阵,最后求解出运动学方程的正逆解,可与后续实际生产中机器人的真实运动情况做对比。应用ANSYS Workbench对底座先进行拓扑优化,在满足刚度和强度要求的情况下,使得底座质量减少了32.6%,优化效果显著。然后再对拓扑优化后的结果进行多目标参数优化,使其在满足要求的前提下,底座所受的等效应力值尽可能减小,优化效果更好。
In the SolidWorks environment, a kind of series connection robot with five degrees of freedom was designed to fit for automatic stamping production line, and a detailed process description of the loading and unloading of robot was presented. At the same time, the theoretical analysis of the above moving was carried out by mathematical model, two kinds of robot coordinate system was established by the D-H method. Then, the kinematic parameters, joint variables and homogeneous transformation matrix were listed. Finally, the positive and negative solutions of the kinematics equation were solved to compare with the actual motion of robot in the actual production. Furthermore, a topology optimization of the base was carried out by ANSYS Workbench, and the quality of base was reduced by 32.6% under the requirements of stiffness and strength. Thus, the optimization effect was significant. Next, the topology optimization results were optimized with the multi-objective parameters to reduce the equivalent stress value of the base as much as possible under the premise of meeting the requirements, and the optimization effect was better.
