Case Study on CAE Tools: Optimization of a 6-axis Robotic Arm for MAG Welding

The design and optimization process of a 6-axis robotic arm for MAG welding is presented, with focus on the arm frame design. Different software tools are compared using the verification models for three types of analyses – dynamic, finite element static stress and fatigue stress analysis. After the appropriate tool was chosen for the task, simplified robotic arm models are made using the market analysis data. Dynamic analysis was conducted on said models and obtained results are used to dimension the initial model ; which was then evaluated using the static stress and fatigue stress analysis. Process itself was iterative and above mentioned steps were repeated until the satisfactory results were achieved. Main advantage of this approach is the use of only one software interface and, since the focus is on the optimization, more energy efficient product.
