Robotic Arm Underfeed Transient Finite Element Analysis Based on ANSYS

摘要: 机械臂凭借高精度、高效率和高可靠性，广泛应用于制造、医疗、物流、农业、服务、科研、军事、建筑和娱乐等领域，推动了自动化和智能化的发展。为了评估其在制造零件下料过程中各个关节的结构强度并确保其在实际应用过程中不会发生破损或变形，本文先利用SolidWorks对机械臂进行三维建模，通过建立运动学模型来准确地描述各个连杆之间的位置关系，再利用ANSYS进行几何模型的导入，最后基于ANSYS Workbench对运转中的机械臂进行瞬态分析，通过这些分析，深入了解了机械臂在不同运行工况下的力学特性，这对于提高机械臂在下料过程中的稳定性和可靠性具有重要意义，并为后续的优化设计提供了理论依据和技术支持。

Abstract: With high precision, high efficiency, and high reliability, robotic arms are widely used in the fields of manufacturing, medical, logistics, agriculture, service, scientific research, military, construction, and entertainment, promoting the development of automation and intelligence. In order to evaluate the structural strength of each joint in the process of manufacturing parts feeding to ensure that it will not be broken or deformed in the process of practical application, this paper first uses SolidWorks to carry out 3D modeling of the robotic arm, accurately describes the positional relationship between each linkage by establishing kinematics model, and then uses ANSYS to import the geometric model, and finally, based on ANSYS Workbench transient analysis of the running mechanical arm, through these analyses, an in-depth understanding of the mechanical properties of the mechanical arm in different operating conditions, which is important for improving the stability and reliability of the mechanical arm in the process of discharging materials, and for the subsequent optimization of the design provides a theoretical basis and technical support.
