تحلیل عددی ارتعاشات پره کمپرسور محوری GE-FRAME 9

In recent years, the analysis of vibrations in turbomachines has been recognized as one of the important and challenging matters in mechanical engineering. This research assessment GE-Frame 9 axial compressor blades and article purpose is to accurately analyze the vibrations and identify the Effective factors of compressor performance and life of these blades. In this article, modal analysis has been done numerically and experimentally, which helps to identify the natural frequencies and modal shapes of blades. This analysis allows to understand the dynamic behavior of blades in different operating conditions. After that, the blade Campbell diagram was extracted from the rotordynamic analysis, which provides important information about the interaction between different components of the compressor and its effect on vibrations. In addition, harmonic analysis has been performed on the blades, which leads to the extraction of the frequency response function diagram. This diagram allows us to examine the frequency response of the blades against different excitations. The results of this research can help to better understand the nature of the phenomenon (or phenomena) that can be the factors of blade vibration. Finally, this study can be a suitable basis for future research in the field of design optimization and vibration reduction in turbomachines.
