JUSTIFICATION OF THE DESIGN SEQUENCE COMBINED SUPPORTS WITH VARIABLE CHARACTERISTICS

The article presents the sequence of calculating a combined support with variable parameters in the form of an algorithm. The application of the graphical editor of the CAE–system APM Win Shaft for modeling a rotor rotating in combined supports with variable characteristics is described. The results of the calculation module are presented. The obtained Kembel diagrams are considered. An analysis is given to the switching diagrams of a combined support with variable characteristics during operation in transient processes according to a certain algorithm. The presented algorithm eliminates the possibility of increasing the amplitude of oscillations when passing through critical frequencies. Conclusions are drawn about the effectiveness of using the specified sequence of calculations Recommendations are given on the use of the proposed calculation sequence for the design of similar combined supports with variable characteristics.
