Abstract
The loss coefficients of vibrational energy play an important role in the analysis of vibroacoustic characteristics occurring in overhead cranes. These coefficients allow us to estimate the rate of vibration attenuation in various structural elements, which, in turn, affects the durability and reliability of the equipment.
Using a dynamometer hammer to excite vibrations is standard practice, as this method allows precise control of the amplitude and frequency of the excited vibrations. Recording the attenuation process at nine octave frequencies provides detailed data on the dynamic characteristics of the system.
Mathematical processing of experimental data makes it possible to identify patterns and establish regression dependencies for various structural elements, such as wheels, wheelset axles, and load-bearing frames. These dependencies can be used to more accurately model the behavior of the system under various operating conditions.
Thus, the regression dependences obtained are an important tool for engineers in the design of overhead cranes, allowing them to optimize their design, taking into account vibration char acteristics and minimizing noise.
