The operation of the executive bodies of soil and soil-cultivating equipment (for example, the teeth of excavator buckets) is often accompanied by the formation and development of local wear, which is the cause of destruction. 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. [ABSTRACT FROM AUTHOR] |
