Review on Vibration Problems in Turbomachinery
Abstract: Vibration suppression of turbomachinery is an important engineering problem. Vibration caused by mass imbalance is a common problem in rotating the turbomachinery systems. Imbalance occurs if the principal axis of inertia of the rotor is not coincident with its geometric axis. Higher speeds cause much greater centrifugal imbalance forces, and the current trend of rotating equipment toward higher power density clearly leads to higher operational speeds. In this paper, a …

Investigation of Seismic Pounding Effect on Symmetric 10 Storey Reinforced Concrete Buildings Using SAP2000
Abstract: ABSTRACT Earthquakes have historically been responsible for significant structural failures, often resulting in substantial economic losses and endangering human lives. One notable failure mechanism observed during seismic activity is seismic pounding, which occurs when adjacent buildings collide due to insufficient separation gaps. This phenomenon is particularly concerning in densely populated urban areas where space constraints often prevent the provision of adequate clearances between structures. Such impacts can lead to severe …

Vibration Analysis of Steel Deck due to Moving Load Using ANSYS.
Abstract: Most anthropological goings-on take in vibration in one arrangement or further. For illustration, we receive for our eardrums vibrate and see because light waves undergo vibration. Breathing is associated with the vibration of lungs and walking involves (periodic) oscillatory motion of legs and hands. Human speech requires the oscillatory motion of larynges (and tongues). Early scholars in the field of vibration concentrated their efforts on understanding the natural phenomena and …

Dynamic Analysis of a Multi-geared Rotor Shaft System
Abstract: Gear systems are the toothed members in which the main aim is to transmit power or motion between two shafts by meshing without any slip. Motion and power transmitted between the shafts are kinematically equivalent to power or motion transmitted between frictional wheels. Vibration of gear system causes unwanted noise such as gear whirling. Noise and vibration signals from machine can contain vital information about the internal processes and provide …

A Review on Hybrid Honeycomb Engine Mounts for Vibration Isolation in Variable Compression Ratio Engines
Abstract: The increasing sophistication of modern engine systems has highlighted the importance of advanced vibration control methods. Engines today are required to function under continuously changing operating conditions, particularly in Variable Compression Ratio (VCR) systems, where vibration behavior becomes highly complex, non-linear, and dependent on time. Under such circumstances, conventional engine mounts often struggle to deliver stable and consistent performance. In contrast, hybrid honeycomb structures offer significant advantages due to their …
