Further, it after obtaining vertical torsion mathematical model coupling, hangs down in basis and turns round the vertical torsion coupling of mathematical model coupling acquisition
During the behavioral characteristics of system:
Milling train coupling stiffness can be according to the product representation of coefficient of coup vibration rigidity corresponding with its, that is, the i-th shaft part
It hangs down and turns round coupling stiffness as TiK=δKi, δ is to hang down to turning round the coefficient of coup.Further, the vertical selection for turning round the coefficient of coup determines that milling train coupling is rigid
The determination of degree, since the application gets up perpendicular system and torsion system by interfacing of working roll, then coupling stiffness be by
It is connected a series-parallel combination of rigidity in working roll and other Various Complex factors influences each other co-determination, and other is more
Kind complicated factor causes very big difficulty to the determination of coupling stiffness, and therefore, the application is by being connected rigidity string simultaneously with working roll
The combination of connection determines the range of coupling stiffness, reduces the selection difficulty of the coefficient of coup, greatly reduces calculation amount, then pass through
The method compared with experimental result then can accurately determine the coefficient of coup.
Specifically, on cold-rolling mill main transmission and top working roll coupling stiffness combining form are as follows: K4And K16Series connection,

Due to the working condition of milling train complexity, the vertical torsion coefficient of coup distribution of system is also more complicated, so calculating
Cheng Zhong can choose a range near above-mentioned calculated value and be screened, find the numerical value to match with measured data, this
Numerical value seeks to the determining practical coefficient of coup.Specifically, it is emulated using MATLAB, exports different hang down and turn round under the coefficient of coup
It hangs down and turns round the torque times magnification numerical value of each shaft part of main transmission of coupled system, then compared with the numerical value of measured data,
It is final to determine torque amplification factor and the coefficient of coup.Wherein, the object of on-the-spot test is Main Drive of Rolling Mill torque signal, the signal
It can directly reflect the torsional oscillation situation of milling train, and include the important informations such as rolling torsion.
Further, it is learnt by mechanical vibration theory, system frequency is the free running frequency for disregarding damping, therefore,
To ignore damping when calculating intrinsic frequency.In addition, solving the intrinsic frequency for turning round coupled system of hanging down according to vertical torsion coupling mathematics
Model specifically acquires to hang down and turns round the characteristic value and feature vector of mathematical model coupling, and corresponding is the flat of system frequency
Side and principal mode, that is, the intrinsic frequency and main formation that theory solves the torsion coupled system that hangs down are moved to formula (2-15) movable machinery,
The intrinsic behavioral characteristics of coupled system are turned round to reflect to hang down.In addition, roll-force and roll torque take reality according to actual condition
Data are solved to hang down using MATLAB and turn round the vibration displacement of coupled system, are obtained to hang down and are turned round the simulation figure of coupled system.
Finally, after obtaining the behavioral characteristics for turning round coupled system that hang down, vibration source analysis method in the prior art, energy are utilized
Enough determine the vibration source of cold-rolling mill, the vibration source of the cold-rolling mill obtained by the above process is accurate, is convenient for discovering device potential faults, protects
Equipment is demonstrate,proved to operate normally.

In order to seek torque amplification factor, torque maximum typically occurs in rolled piece bite stage, and torque mean value then refers to stable rolling
When torque value, by being obtained to live 22 groups of data statistics are as follows: torque maximum 349.3KNm, the maximum of torque mean value
Value is 273.69KNm, torque amplification factor mean value: 1.863.
Then, it is calculated to hang down and turns round the coefficient of coup are as follows:
Then, the vertical torsion coupling coefficient range of pickup is 0.45~0.50, substitutes into the vertical torsion coefficient of coup within the scope of this
It is emulated with MATLAB, exports the different torques for hanging down the sagging each shaft part of main transmission for turning round coupled system of the torsion coefficient of coup and put
Big multiple value as shown in figure 5, be 1.863 according to the average torque amplification coefficient that aforementioned field measurement obtains universal-joint spindle,
The calculated value that the experiment value of spindle torque amplification factor is obtained with emulation is compared, obtaining result is shown in Fig. 6.Pass through reality
Measured value is compared with calculated value, and calculated value and measured value are closest when coefficient of coup δ is 0.463 as seen from Figure 6, therefore
Determine that the coefficient of coup is 0.463.
Again with mechanical vibration theory to the kinetic model and mathematics model solution intrinsic frequency built and main formation.It hangs down
It turns round in coupled system, does not apply roll torque at roll and only apply roll-force, mathematical model are as follows:
Dynamics simulation is carried out to it, obtains the response diagram of the torsion angle of each shaft part when only roll-force effect at any time,
As shown in Fig. 7-Figure 15.
It hangs down and turns round in coupled system, do not apply roll-force at roll and only apply roll torque, mathematical model are as follows:
Dynamics simulation is carried out to it, obtains when only roll torque effect perpendicular system each mass block vibration displacement at any time
Between response diagram, as shown in Figure 16-Figure 20.
It is turned round in coupled system hanging down, roll-force should be applied at roll and apply roll torque, mathematical model again are as follows:
