COMPUTATIONAL INVESTIGATION OF DYNAMIC BEHAVIOUR OF MULTI-CRACKED ROTOR SYSTEM USING BONDGRAPH TECHNIQUE

In this research, the bending moment at the fracture site is calculated using an equation of motion that explicitly includes the extra slope required to account for crack breathing. Inversely, using a principle from fracture mechanics, the extra slope is determined by integrating across the crack area. The transfer matrix technique is used to construct the rotor's reaction after a fracture has been introduced. For both transient and steady-state responses, this study takes a fresh tack by developing a specialized technique for calculating the calibrated internal damping factor for bond graph dynamic analysis. Metal matrix composites with very long and thin shafts have been studied. This study sheds light on how the dynamic response of composite shafts might vary depending on their specific make-up.
