This regularization method uses a constant damping parameter – only for equations corresponding to unknown limits. For all the other equations, equations No. 0 and [D] -[I] are used, because the biggest errors occur at borders where temperatures and river means are unknown. When a second-order system has < ζ < 1 "display style" (i.e. when the system is under-tempered), it has two complex conjugation poles, each having a real part of "α "display style"; In other words, the disintegration rate parameter α "displaystyle" represents the rate of exponential disintegration of vibrations. A lower depreciation ratio implies a lower rate of decay, and very weak systems oscillate for long periods of time. [5] For example, a high-quality pitch, which has a very low damping ratio, has a vibration that lasts a long time and disintegrates very slowly after being struck by a hammer. External weakening appears to be the result of the interaction between a mechanical system and the external environment. These may be the following types: The main technological parameters of the system studied are: 130 kg disk mass, tree stiffness and each squirrel spring 7.0 MN/m, 1.0 MN/m, the external insulation coefficient of the 50 Ns/m glass and the 7.8 kg disc.

Finally, we show the results of the simultaneous evaluation of the material constants and the point of application of the load. It is assumed that the load applied is the same as in the example above. The numerical results are summarized in Tables 5 to 7, which shows an excellent agreement between the exact results and the estimated results, even if some measurement errors are included. The numbers in brackets indicate errors in the carnation days between the estimated values and the target values of the parameters. If (const. weakening is called linear weakening; if c -c (t), depreciation is called parametric damping; and if it is (q), c-c (q), c (q), q) or c -c (q), q, q, t), impairment is called complex impairment. The identified minimum damping capacity of a dry ball bearing (without lubricant) can be estimated fairly accurately with an hv loss factor commonly used in material damping theory. The empirical approach: refers to a simple relationship between the unknown c bearing damping coefficient and the calculated rolling rigidity coefficient k. The term f describes the frequency of vibrations, DED the energy discharged by charge cycle and DEV the maximum energy by elastic deformation. Factor Q, amortization ratio ζ and the rate of exponential decay α are so related[4] The bottom half of Figure 6 compares the depreciation values of experimentally identified bearings to those obtained by the theoretical approach described. Apart from slightly pre-stressed bearings, the diagram shows a good correlation between measured and calculated values.

The coefficient of depreciation viscose for a degree of freedom q is the minimization of the rest plus impunity. The shape of the damping matrix determines which penalty is used, and the depreciation parameters, the penalty is weighted for each equation. These weights must be determined based on the error associated with the respective equation. From the definition of the amortization parameters [Eq. (1) and Eq. (9) we find the source #4 the damping of materials by the deformation of Hertz mills and quarries. The force transmitted between the rotor and the stationary part is composed of three components: the elastic force transmitted by the squirrel`s spring and the damping forces transmitted by the layers of normal and magnetological oils.
