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.
To modelling of phenomenons of internal dynamics of systems with strong non-analytical nonlinearities
Škuderová, Alena
The creation of model of two spur gears with elastic supports so, in order that to waht mostly approximate real fact, was the aim of this work. This model considers the influence of motion in bearings not only at direction of line of mesh, but and at al direction, the damping and periodically variable stiffness into the gear mesh, frictional forces, possibly eccentricity of gears or manufacturing inaccuracy of teeth profile and influences of impacts, caused by existence of backlash.
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.
