Recovery trains are a specific type of railway formation comprised of a huge amount of special equipment used for prompt and high-quality elimination of accident consequences and restoration of railway communication. Depending on the type of recovery train, power station cars can have various configurations and be equipped with different numbers of autonomous diesel generator units required to perform the preset functions. Diesel generators installed in these cars are located in proximity to workplaces and the place of locomotive drivers, which creates an adverse vibroacoustic environment during a working shift.
The article aims at the detection of potentially hazardous and harmful production factors emerging inside a power station car and the experimental investigation of noise and vibration. The experimental investigations inside power station cars have detected a significant excess of vibroacoustic characteristics compared to the established sanitary and hygienic norms. The consequences of noise-induced hearing loss and vibration disease caused by the long-term effect of noise and vibration are known. Hence, the problems of the investigation are urgent and a matter of great scientific and technological, social and economic importance.
Within the framework of the investigation, it has been concluded that considering the established class of working conditions and production tasks of a locomotive driver of a power station car it is reasonable to take measures to reduce the general vibration level at the driver’s workplace. The goal can be achieved via the modernization of the driver’s chair racks by using vibration-absorbing elements. In the course of the development of engineering solutions, the fact that the sound field is formed from air-based and structural components as well as the specific car configuration have been considered.
