Characteristics Analysis of Non-linear Torsional Vibration in Engine and Generator Shafting system
Abstract: To solve the
non-linear torsional vibration problem of engine and generator shafting causing
body structural vibration and noise in motorized wheel vehicle, where the
engine and the generator connected directly. First of all, analysis the
characteristics of the shafting system, besides the external shock excitation
of engine and generator. Then, through lumped parameter model method,
mathematical model of the non-linear torsional vibration was established, which
could reflect the dynamic characteristics of the system. Analysis the effect of
mechanical parameters and electromagnetic parameters on the shafting. And get
the non-linear differential equations of the system torsional vibration, which
expresses the relation between structural parameters, electromagnetic
parameters and the system dynamic characteristics. And multiple scales method
was used to solve the equations. Non-contact measurement method was used in the
torsional vibration test. Finally, consistency of the results, indicate that
the research method used is reliability and accuracy, and get the critical
speed of the shafting torsional vibration.
