For the first row, second formula is subtracted from the first row as the second row, introduces dimensionless group ρ1ρ2, κ1, κ2, and
They are finally write into matrix form, the frequency catching equation of two vibrators can be expressed as：
Wherein
Equation (10) describes the coupled relation of two vibrators, and be referred to as the dimensionless coupling of two vibrators etc.
Formula.
3) standard of frequency catching is realized
WillWithSubstitute into equation (10), obtain u1=0 and u2=0, calculate u1 and u2's and with difference, by it
Rearrange,
In equation (11), Te01+Te02It is the summation of the electromagnetic torque of two motors；(f1+f2)ωm0It is two motor
Rotor damping torque；χf1+χf2It is the summation for the load torque that vibrational system is acted on two motors.Equation (11), be

The remaining electromagnetic torque of motor 1 and 2.BecauseRealizing the standard of Vibration Synchronization is
TC≥|TD| (14)
The synchronization criterion of equation (14) two vibrators of expression is that the torque of frequency acquisition is equal to or more than two motors
Poor absolute value between remaining electromagnetic torque.
Equation (11) and (12) are ωm0WithNonlinear function, their solutionWithNumerical method can be passed through
To determine.
4) stability of synchronous regime
Locate lienarized equation (10), add the third lineThen they are written as three
The system of individual differential equation of first order, and use symbol
Wherein,
It should be noted that a 'ijWith b 'ijRepresenting matrix aijAnd bijValue, A and B are representedWith
It is inserted into equation (15).det(A′-1B '-λ I)=0, derive the characteristic equation of eigenvalue λ
λ3+c1λ2+c2λ+c3=0 (16)
Wherein,
In engineering, WcAnd c1,c2With c3Compared to very small, can ignore.It can be reduced to：
Based on Routh-Hurwitz criterions, the λ in and if only if equation (16) has negative real part, and equation (19) has solution, equation
(15) null solution z=0, it is stable, i.e. stability of a system condition is:
c1>0, c3>0, c1c2>c3 (19)
Equation (19) can be rewritten as (20) and (21)
H′0>0, H '1>0, H '3>0,4H '1H′2-H′0H′3>0 (20)
H′0<0, H '1<0, H '3<0,4H '1H′2-H′0H′3>0 (21)
Due to H '0>0 and H '1>0(κ1>0, κ2>0), can be inferred that
Again because H '3>0, obtain
H '0, H '1, H '24H ' is substituted into H ' 31H′2-H′0H′3>0
As shown in formula (24), ifThe left side of equation (24) is much larger than 0, and the right is less than 0, ρ1>0, ρ2>
0.Therefore, equation (22) and (23) meet equation (24).
As H '0<0, due to H '1<0, obtain ρ1k2+ρ2k1<0, H '3<0 requiresIn this case, side
The left side of formula (24) is less than 0, and the right is more than 0.H′0<0, H '1<0, H '3<0, it is unsatisfactory for 4H '1H′2-H′0H′3>0。
In additionMeet equation (23),There is θcDetermine.Therefore, equation (22) and (23) are two
The stability criterion of the synchronous regime of individual vibrator.
