Mоdeling and Analysis оf Interactiоns in the Rоtor–Bearing–Housing System under Variable Loads
Abstract
Vibration arising in industrial settings significantly influences the durability and functionality of machinery, particularly those operating under high speeds and heavy loads. Despite ongoing technological improvements, sectors such as textiles continue to experience intensified vibration, impulsive noise, and broadened frequency emissions due to the integration of more potent machinery. Devices like shuttle looms and cotton-processing equipment exemplify systems that contribute to vibrational challenges. This research explores the dynamics of the "rotor–bearing–housing" assembly as a key factor in mitigating such issues. Given that rolling bearings frequently develop defects that compromise mechanical performance, the study introduces an advanced dynamic model considering deformation, misalignment, and fluctuating contact stresses under vibration. Emphasis is placed on the influence of bearing design, stiffness, and applied loads on overall system stability. The paper also reviews modern vibroacoustic diagnostic techniques for early failure detection and service life forecasting, promoting more efficient and resilient vibration control solutions in industrial environments.
