Determination of the Boundaries of Changes in External Parameters that Complicate the Calculation of the Suspension of Agricultural Machinery

Introduction. The article deals with the problem of calculating strength shaft wheel drive agricultural machinery. conditions both maximum torque and values relative deformations are taken into account. Aim Article. Of research is to determine limits external influences on a structural element, caused by distributed weight motor-tractor machinery, at which it necessary construct not only strain diagrams, but also extreme each section, where index structure nonlinear. Materials Methods. In calculations, main provisions continuum mechanics, theory machines mechanisms, as well basics design in mechanical engineering used. Central attention paid influence influencing factors character internal force distribution shaft. Results. obtained area variation parameters P-q allows us necessity more detailed calculation considered part. This due emergence areas outside boundaries individual consideration work. results presented two-dimensional graph ratio influences, specified effect takes place. Discussion Conclusion. comparison typical regulated normative documents, proposed algorithm preliminary stage cases when nonlinear regions bending moment changes require additional investigations. use allows, without resorting time-consuming numerical methods indicators shaft, such finite element method, obtain picture nature forces part under study.
