基于ANSYS的机械臂吹扫装置

Simulation Analysis of Mechanical Arm Purging Device Based on ANSYS

为了解决机械臂对表壳外表面完成抛光后机械臂易与表壳发生粘连的问题,笔者设计了机械臂吹扫装置,并讨论了该装置2种不同进气口位置的设计方案。利用SolidWorks建立2种方案的三维模型,将其导入到ANSYS软件中,利用FLUENT模块进行流体动力学仿真分析。根据迭代计算曲线和压力分布云图,得出2种方案均可使表壳顺利脱离。通过2种方案的流迹线云图和速度矢量图进行对比分析,结果表明进气口在喷嘴正上方的装置吹气质量更优。研究结果有助于工作人员选择合理的方案。

The mechanism arm purging device was designed to solve the problem of adhesion between the manipulator and the surface shell after polishing work,and the design scheme of two different air inlet positions of the device was discussed.The three-dimensional model of the two devices was established by using the SolidWorks,and the model was imported into the ANSYS software and the FLUENT module was used for hydrodynamic simulation analysis.According to the iterative calculation curve and the pressure distribution cloud diagram,it can be concluded that both schemes can realize the function of separating the surface shell smoothly.Through the comparison and analysis of the flow trace line cloud diagram and the velocity vector diagram of the two schemes,the result shows that the air quality of the device with the air inlet directly above the nozzle is better.The research results provide reference to help the staff to choose a reasonable plan.
