The Derivation of the Noise Level Dependences and Vibration Velocities of Elements and Units of the Drive System of the Rail Grinding Machines

Abstract

Abstract The paper is devoted to the derivation of the noise level dependences and vibration velocities of elements and units of the drive system of the rail grinding machines. It should be noted that the vibro-acoustic characteristics of the drive system of rail grinding machines have not been studied enough. The negative impact on the operator of the increased vibration and noise levels is known as diseases caused by noise and vibration are the second and third in the list of occupational diseases. It should be highlighted that the safety in the operation of rail grinders largely depends on operator fatigue, which is actually determined by the influence of vibration and noise. Consequently, the problem of the vibro-acoustic safety of the rail grinding machines is relevant and has both technological and socio-economic significance. This article presents the results of theoretical studies of the processes of vibration excitation and generation of wheelset noise as one of the main causes of the increased noise in the general drive acoustic system of the rail grinders.
