DEVELOPMENT OF METHODS AND AIDS FOR NONDESTRUCTIVE CONTROL IN PRODUCTION OF AIRCRAFT ELEMENTS

The aim is to increase the quality and reliability of the mechanical engineering articles at the expense of creating and introducing methods and nondestructive control and technical diagnostics in the operation processes of the articles. The model for prognosis of the serviceability in the friction assemblies according to the acoustic characteristics of the contact has been proposed. The new energetical criteria have been substantited. The methods for determination of the state in the friction surfaces, actual area of the touching and wear of the tool have been developed. Application field: control of structural state in structural and tooling materialsAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
