Abstract
Objectives The most important problem of modern mechanical engineering is increase in durability of products, their efficiency and competitiveness in the world market. The equipment for machining creates the increased noise levels in a working zone of operators. Now regularities of formation of acoustic characteristics are studied generally for metal-cutting and woodworking machines of various types. Formation of the sound field at shariko-rod hardening is studied insufficiently. The purpose of researches which results are given in this article consisted in studying of regularities of spectral structure of noise and vibrations when processing ShSU of details with various ways of fixing. Method. In the course of pilot studies the known methods of measurement and processing of experimental data in relation to acoustic and vibration characteristics were used. Results. It is established that noise ranges at ShSU of details with various ways of fixing have identical regularities of a shumoobrazovaniye and are characterized by pronounced high-frequency character. It is proved that the dominating sources yaa-lyatsya the strengthened detail and an uprochnitel. Conclusion. Sizes of excesses of levels of sound pressure systems "up-rochnitel-detal2 in a high-frequency part of a range 500-8000gts are installed. The established regularities of formation of spectral structure are a basis for the choice of means of decrease in noise levels. Work is performed within initiative research work.
