Abstract

With the advancement in technology in the recent past and the automation of industrial processes, the field of robotics has evolved significantly. Most of the processes on the industrial level and in aerospace sector are being done with the help of robots and robotic arms. Due to this, the strength and structural integrity of robots has become a critical topic for investigation. This study evaluates structural analysis and cost analysis to produce a connecting rod for an articulated robotic arm using Steel and Aluminium alloys. The model of a connecting rod is created in the SOLIDWORKS® whereas the simulation is done on ANSYS® at three-moment values i.e., 500 Nm, 600 Nm and 700 Nm respectively. 5 Steel alloys (i.e., 304L Stainless Steel, annealed 310 Stainless Steel, annealed 316L Stainless Steel, quenched 410 Stainless Steel and annealed 446 Stainless Steel) and 5 Aluminium alloys (i.e., Aluminium alloy 5052-H32, Aluminium alloy 5086-H34, Aluminium alloy 6061-T8, Aluminium alloy 6063-T83 and Aluminium alloy 7075-T76) are used for simulation. Deformation, strain and stress values for each alloy are calculated at the aforementioned moment values. The cost analysis is done based on the volume of the connecting rod and the material required to produce that connecting rod. The results showed that annealed 310 Stainless Steel is the best choice among the analyzed alloys for enhanced strength and reduced deformation. On the other hand, 5086 Aluminium alloy is economical for the production of connecting rods but its strength is much lower than that of Steel. 304L Steel alloy is economical and deformation closer to 310 Stainless Steel alloy but its factor of safety is significantly less than that of 310 Stainless Steel. So, the optimal material for the production of a connecting rod for an articulated robotic arm is 310 Stainless Steel.
