摘要
为满足智慧图书馆存、取书的需求,本研究设计了一款专用于智慧图书馆的抓书机械手.根据实际抓书工况的需求,基于Soildworks软件设计出一款末端执行器,并对末端执行器进行有限元分析.对并联机构建立笛卡尔坐标系,最后基于蒙特卡洛法对工作空间进行仿真验证.本研究最终将设计所得的末端执行器与并联机构相结合,得到一款能够快速、稳定抓取书本的机械手.根据仿真结果可知,所设计的抓书机械手可达到实际工况要求.
Abstract
In order to meet the needs of the smart library for storing and retrieving books,a book grabbing manipulator dedicated to the smart library was designed.In this study,an end effector was designed based on Soildworks software according to the requirements of the actual book grasping condition,and the end effector was analyzed with finite element analysis.The Cartesian coordinate system was established for the parallel mechanism,and the kinematic analysis was carried out,and the workspace was simulated and verified based on Monte Carlo method.Finally,the designed end effector was combined with a parallel mechanism to obtain a manipulator that can grasp books quickly and stably.According to the simulation results,it can be seen that the designed book grabbing manipulator can meet the requirements of actual working conditions.
