Welding Parameter Optimization of Alloy Material by Friction Stir Welding using Taguchi Approach

Friction stir welding is used as a solid state joining process for soft materials such as aluminium alloys and also for hard materials like steels. It avoids many of the common problems obtained in fusion welding. In mechanical, civil, automobile, naval, and aeronautical engineering beams are widely used of the magnesium alloys for different applications and that are joined by conventional iner...

Parameters Assignment of Electric Train Controller by Using Gravitational Search Optimization Algorithm

The speed profile of the train will be determined according to criteria such as safety, travel convenience, and the type of electric motor used for traction. Due to the passengers and cargo on the train, the electric train load is constantly changing. This will require reassigning the speed controller’s parameters of the electric train. For this purpose, the Gravitational Search optimization Al...

Compliant Robot Behavior Using Servo Actuator Models Identified by Iterative Learning Control

System parameter identification is a necessary prerequisite for model-based control. In this paper, we propose an approach to estimate model parameters of robot servo actuators that does not require special testing equipment. We use Iterative Learning Control to determine the motor commands needed to follow a reference trajectory. To identify parameters, we fit a model for DC motors and frictio...

Optimization of the parameters of low-carbon steel (EN10130) welding using friction stir welding method

  Friction-stir welding process is a novel method of solid state welding, which produces heat due to friction between the pin, the shoulder and the workpiece. This heat causes a paste area. Shoulder pressure and pin spin cause edges integration and lead to welding. In this study, firstly, the feasibility of welding of steel sheet (EN10130) with a thickness of 1.5mm has been tested by 58 experim...
