Optimization of Bearing Location for Multi-Stepped Rotor by Genetic Algorithm

چکیده مقاله

The optimization of the design of systems containing rotating shafts, so that the
system has appropriate vibration characteristics, is one of the most important factors
involved in the performance and efficiency of the rotor system operations. Vibration of rotary
equipment is usually caused by factors such as unbalanced mis-alignment, abrasion parts,
and abrasion moving parts. The frequency of these vibration forces is usually an integer
multiple of rotating speed (spin rate) so that if the initial critical speed is as far away as …
