In this research, while investigating the vibration analysis of rotary axes, we specifically investigate the rotor of a turbofan engine used in the industry. The features of this rotor range are high-performance, lightweight, and low-vibration range. These three factors are in contradiction with each other, resulting in a thorough examination of th...

In this paper, the vibrational analysis of the turbine blade and the effect of pressure on the rotor surface in the fluid–structure interaction are investigated. Due to the complex and specific working conditions of a turbine blade, the FSI phenomenon, as well as modal analysis, has been investigated in this work. The turbine blade was exposed to c...

In analyzing robot manipulator kinematics, we need to describe relative movement of adjacent linkages or joints in order to obtain the pose of end effector (both position and orientation) in reference coordinate frame. Denavit-Hartenberg established a method based on a 4×4 homogenous matrix so called “A” matrix. This method used by most of the auth...

The effect of flutter phenomenon on dynamic stability of aeroelastic systems is a main interest of recent studies. Among many approaches for suppression of flutter, in this paper two control strategies are introduced and their results are compared. State-Dependent Riccati Equation (SDRE) approach and Sliding Mode Control (SMC) approach are used for...

Magneto- Rheological (MR) damper is a new generation of dampers, filled up with a MR fluid. This fluid, when exposed to a magnetic field, will transform regularly from a slipper linear viscous fluid to a semi rigid state. In this article, semi-active control of structures equipped with MR damper is studied. For this purpose, fuzzy control theory is...
