| dc.description.abstract | The new trend in luxury car painting detailing includes the utilization of cutting-edge technology such as the ABB painting robot IRB 5500, which offers precise and efficient painting capabilities. This advanced robotic system enhances the overall quality and aesthetics of luxury cars while reducing manual labor and increasing productivity in the automotive industry. There Comes the demand of improved version of IRB 5500 painting
robot and this paper discusses the modal analysis of this painting robot.
The primary objective of this thesis is to identify the robot’s natural frequencies and corresponding mode shapes, which are critical in understanding its dynamic behavior and optimizing its performance. Accurate knowledge of the robot’s natural frequencies helps avoid resonance conditions that can lead to excessive vibration, reduced accuracy, and even structural damage. Mode shapes provide insights into the spatial distribution of robot deformations during different vibration modes, aiding in design improvements and identifying potential sources of instability. Thesis involves 3D modeling and Autodesk Inventor, meshing and analysis by ANSYS Workbench.
To achieve the goal, the project involves several key steps. First, a detailed finite element model of the robot is developed within the ANSYS software environment. The author have considered two configuration of IRB 5500 robot for the study. the Material properties, boundary conditions, and connection interfaces are also incorporated to simulate the real-world operating conditions. Next, modal analysis techniques are applied
to the finite element model to determine the natural frequencies and mode shapes. The results obtained from this analysis aid in identifying critical frequencies and modes that may have implications for the robot’s performance and structural integrity.The obtained mode shapes enable engineers to identify regions of high deformation and assess their impact on the robot’s performance and reliability. | |
