Abstract
The bearing frames of overhead cranes are made of channels of different sizes. Linear radiators are used as a noise source model, since the length of the source significantly exceeds the maximum size of the cross-section. The calculation of oscillation rates for an energetically closed system consisting of rod elements is based on the energy balance equations. Reducing the intensity of sound radiation can be performed either by reducing the vibration power introduced into the frame from vibration sources such as gearboxes of lifting and moving mechanisms, wheelset assemblies and the drum of the lifting mechanism, or by increasing the dissipative properties of the frame elements. This paper presents the calculation of the oscillation rates of the supporting frame and shows the effect of the vibration absorption system on reducing noise levels.
