Finite Element Analysis of the Small Arm of a Handling Robot Arm Based on ANSYS

随着机械臂的广泛应用，对其加工性能的要求也日益提高。小臂作为机械臂的核心部件，在很大程度上决定了整个机械臂的性能，包括其结构和功能。针对小臂的可靠性和安全性问题，本文基于ANSYS软件对机械臂的小臂进行了有限元分析。先利用SolidWorks软件对机械臂小臂进行三维建模，利用ANSYS进行几何模型的导入，再基于ANSYS对其进行静力分析，通过施加不同载荷情况模拟了其在工作过程中的受力情况，然后结合模态分析以及频率响应特性分析。通过分析结果，对机械臂小臂的结构进行优化改进，对比分析两种方案下的机械臂小臂的稳定性和可靠性，得到优化结果，从而提高机械臂小臂性能。
With the wide application of robotic arms, the requirements for their machining performance are increasing. As the core component of the robot arm, the small arm largely determines the performance of the whole robot arm, including its structure and function. To address the reliability and safety of the arm, this paper is based on ANSYS software to finite element analysis of the arm of the robot arm. SolidWorks software is used to model the arm in three dimensions, ANSYS is used to import the geometric model, and then ANSYS is used to carry out the static analysis, simulate the force during the working process by applying different loads, and then combine with the modal analysis and the frequency response characteristic analysis. Through the analysis results, the structure of the small arm of the robotic arm is optimized and improved, and the stability and reliability of the small arm of the robotic arm under the two scenarios are compared and analyzed, and the optimization results are obtained, so as to improve the performance of the small arm of the robotic arm.
