The dependence of the rheological properties of a lubricant under turbulent friction on the pressure and temperature is considered. As a result, the velocity and pressure fields in the axial groove and on the surface of the polymer antifriction composite coating have been determined, as have the load capacity and friction force, which make it possible to increase the load capacity, reduce the friction coefficient (increase the wear resistance), and also increase the duration of the hydrodynamic mode.

Meanwhile, well-known theoretical studies devoted to the study of working conditions and forecasting the resource of such parts are few and are of a private nature, stipulated by the solution of specific problems. This article deals with cantilever-fixed parts in the case of prevailing wear in local areas of the working surface. A rectangular cantilever fixed beam subjected to bending with a section where a groove simulating wear is located is considered as a calculation model. It has been established that the working state of a cantilever-fixed part with the presence of local wear is determined by a system of inequalities relating its geometry to the allowable stresses and pressure of the wear medium. A mathematical model has been obtained facilitating prediction of the resource of a part as its wear develops.</p>","PeriodicalId":642,"journal":{"name":"Journal of Machinery Manufacture and Reliability","volume":"52 1 supplement","pages":"S26 - S31"},"PeriodicalIF":0.4,"publicationDate":"2024-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139751850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The vibration amplitudes of the platform and the mutual phase of rotation of the vibration exciters as a function of excitation frequency were obtained for various weights of the loads installed on the platform.
