Abstract

The paper presents deformation calculations of the basic cylinder of the rotary screw propulsion unit under external load. The influence of such basic parameters of the rotary screw propulsion unit as basic cylinder diameter, its length and wall thickness on its deformation area, and, as a consequence, the generated noise level has been demonstrated. The basis for the method development were studies by scientists who were studying the sound wave generation by the deformation of different structural elements, parts and assemblies. The contribution of each of the parameters of the basic cylinder to the general level of the generated sound pressure was analyzed. It was determined that the magnitude of the noise level is mostly dependent on the length of the basic cylinder, then, to a less extent, on the cylinder wall thickness, and, to the least extent, on its diameter. A correlation was revealed between the oscillations power of the propulsion unit and their correlation with their generated noise level. The results and conclusions obtained during the described study allow for a more solid-based approach to the parameter selection of the rotary-screw propulsion unit for improved acoustic comfort, also for improved driver's work conditions, including the relief of his/her nervous system, sharpening of his/her attention during the operation, accident reduction. Beside the design of structures with the least possible noise, the proposed method allows also for selection of a rational propulsion unit design achieving a compromise between vehicle's noise specifications and its off-road ability.
