Optimal Design of Robotic Arm Components by Integrating Topology Optimization for FDM Technique

Topology optimization of robotic arm components like base and lower link.

Created on 2019.05.27 26 views
•The project work is carried out for fine-tuning of component design in Additive Manufacturing. There is a need to generate functional design to reduce the weight and material used for component and its support without compromising part strength and performance to make component right the first time using the Topology Optimization approach. Topology optimization is a freeform design methodology that allows for the design of components or systems based on prescribed loads and boundary conditions along with a defined design domain. The component selected is the base and lower link of the Robotic Arm with 6 dof and size 370mm with a payload capacity of 270g. •The topology optimization of the robotic arm is done using 3D EXPERIENCE Platform. The parts to be optimized are base and lower link. The Functional Generative Design (FGD) module of 3D EXPERIENCE Platform provides an integrated solution to create a new generation of function driven parts. •The steps in the Functional Generative Design module are –Defining functional specificationsCreating conceptual shapes and performing a trade-off studyModelling optimized shape design Thus by following the above steps topology optimization of the base cylinder and the lower link is done. •The optimization target is mass reduction up to 40% of the original mass for all parts. •The optimized designs are 3D printed using ABS material on Lulzbot Taz 6 3D printer with the build volume of 280mm x 280mm x 250mm. •This project is carried out in the Product Innovation Lab at Walchand College of Engineering, Sangli under the guidance of Dr Sagar Sapkal and Prof. Bipin Shevade.
