Optimization of EOD manipulator arm's lattice for 3D printing
In this article,with the focus on the explosive disposal robot's manipulator arm,an EOD manipulator arm for 3D printing is designed.The three-dimensional model of the manipulator arm is set up by means of SolidWorks;the static analysis is conducted on the original boom is carried out with the help of ANSYS Workbench,and then boom is subject to topology optimiza-tion according to the analytical results.While meeting the boom's working requirements,Altair Inspire is used to fill the opti-mized boom with three grid structures with different diameters.The static analysis is conducted on the optimized boom through In-spire.Compared with the original boom,the optimized manipulator arm meets the working requirements.Besides,it enjoys light-weight design and better bearing capacity;the end effector has higher accuracy,and the safety of explosion removal is enhanced.The 3D printing technology is helpful to solve such problems as complex optimization and difficult processing of the boom model on one hand and improve the efficiency in design and manufacturing on the other hand.
