Annotation

Precise and approximate equations describing torsional oscillations in force transmissions containing a cardan shaft are considered in the article. Using approximate equations can significantly reduce the amount of calculations, in connection with which, they can be used to calculate models of power transmission of transport vehicles with many degrees of freedom. 

The results of numerical experiments showed that the perturbing forces acting on the cardan transmission elements and leading to high-frequency oscillations are caused by the kinematical and parametric oscillations of the cardan transmission itself from the effect of its rotation with time-varying oscillations of the angle of fracture of the axes of the connected cardan shafts, and also perturbations from the engine.

Based on the results of computational studies of the multi-mass model of an earth-moving caterpillar mashine containing cardan gear and comparing them with experiment, recommendations are given to reduce the level of dynamic loads in elements and components of the structure.

 

Keywords: systems with many degrees of freedom, power transmissions, cardan gears, torsional vibrations, Newton's method, harmonic balance method

History of journal:

In June 1994 the 2nd International Scientific and Technical Conference "Application of vibrations for technological purposes" was organized on the basis of Vinnytsia State Agricultural Institute. Leading experts in this field, noting the significant contribution to the school of Vibration Engineering under the leadership of P. S. Bernyk, proposed to create a professional all-Ukrainian scientific and technical journal "Vibration in engineering and technology..The journal was foundedat Vinnytsia State Agricultural Institute and P.S. Bernyk was elected to be the chief editor .
For all these years (since 1994) theJournal "vibration in engineering and technology" published  94 issues wherestudy of vibration effects, the creation of progressive energy saving technologies and equipment for their implementation were highlighted.
Currently Kaletnik H.M  PhD , professor, academician NAAS is the chief editor of the "Vibrations in engineering  and Technology"
The journal "Vibration in Engineering and technology", which has no analogues on the territory of Ukraine, is well known abroad.
