To the analysis of the bearing stiffness influence on the amplitude frequency characteristic of the gear wheels
Hortel, Milan ; Škuderová, Alena
To the analysis of the bearing stiffness influence on the amplitude frequency characteristic of the gear wheels.This contribution deals with the theory of planar steady damped oscillation of the isolated pair of spur gear, which is in two orthogonal direction elastically suspended. The analysis of the periodical solution was carried out by means of transformation of the differential boundary-value problem to the integral problem with the successive approximation and simulation method. The purpose is the determination of the bearing stiffness influence on the dynamic force in gearing mesh.
The integrodifferential theory i the analysis of damping influence of internal dynamic of nonlinlinear parametric systems
Hortel, Milan ; Škuderová, Alena
This contribution deals with the analysis of influence of damping of nonlinear parametrical systems with kinematic couplings - gear teeth. There is used the integrodifferential theory with the E.Schmidt resolvent kernel splitting method as the mathematical method for the analysis of such complicated dynamical problems.
To the analysis of dynamic phenomena in strongly nonlinear systems with kinematic couplings and split power flow
Hortel, Milan ; Škuderová, Alena
High parametric systems with split power flow are often applied in aeronautical industry and in crawler vehicles with restricted leg for power units. The motion in such systems leads by the mass discretisation to the solution of ordinary deterministic nonlinear parametric differential equations with time variable terms. Their solution can be carried out by means of analytical integral methods or by means of numerical methods - computer simulation.
Identification of impacts in drive systems
Kratochvíl, Ctirad ; Grepl, Robert
In the last few years apears the existence of problems by controled drive systems because of impacts. Directly in mechanical constraints and also in control subsystems. Conditions of its existence where study mostly for systems with 1 or 2 DOF.
At problems of regular and irregular - chaotic motions in faintly and strongly nonlinear gearing systems
Hortel, Milan ; Škuderová, Alena
The dynamic force is the basis for the minimalization of mass and measures of engineering structures. Gear pair models which mostly approximate the real fact lead to the solution and analysis of nonlinear differential equations with time variable structure.

Hortel, Milan ; Škuderová, Alena
The contribution deals with analyzing of influence of damping on qualitative behaviour of nonlinear mechanical systems with kinematic couplings - gear teeth. It is solved the influence of linear and nonlinear cubic damping on regular and irregular m on of chaotic character.
Simulation of impact´s effects in nonlinear parametric systems
Škuderová, Alena
The creation of gear pair model with elastic bearings was the aim this work. The model considers the influence of motion in bearings nor only at direction of line of mesh, but and at normal direction, the damping and periodically variable stiffness in the gear mesh, frictional forces, possibly eccentricity of gears or manufacturing inaccuracy of teeth profile and influence of impacts caused by existence of backlash.

Hortel, Milan
Some problems by the analysis of the dynamic of mechanical systems lead on the solution of nonlinear integrodifferential equations. The Kneser functions are by the constructions of the kernels in the form of Gree´s function discussed.

Hortel, Milan ; Škuderová, Alena
In this contribution is showed results of the solution of nonlinear parametric systemswith kinematic couplings gain through the method of analytical solution and with numerical simulation.
Simulation of dynamic phenomenons in nonlinear parametric systems with kinematic coupling and backlash
Škuderová, Alena
For verification analytical results of solving inner dynamics on nonlinear parametric system was built simulation model of stiff bearing external spur gearing, which respects except variable stiffness - given change numbers of tooth in mesh - also influence of geometrical departure evolventy curve from ideal profil side tooth. Simulation model of system with two degrees of freedom covers region of normal mesh, tchnological backlash and areas of inverse mesh.
