Contribution to mathematical modeling of drive parasitic vibration
Kratochvíl, Ctirad ; Kalous, J. ; Kotek, Vladimír
This article deals with the simulation of dynamic responses of electromechanical drive systems using mathematical-numerical methods. We constructed an idealized torsion system of the mechanical part of the real drive to examine the parasitic effects.

Dynamic properties of driving systems - composite method of analysis
Chalupa, M. ; Kratochvíl, Ctirad ; Heriban, P. ; Kotek, Vladimír
The article contains the description of technical measurement application of hydraulic pressure in hydraulic control system of planetary gearbox with three freedom degrees and practical example of the modelling of the influence different courses control pressures on the quantity of dynamic load of toothed wheel of planetary gearbox mechanism. It is used the dynamic properties of driving systems composite method of analysis for the modelling.
The Compare of Dynamic Properties of Electromechanical Drive Systems with
Kratochvíl, Ctirad ; Procházka, František ; Pulkrábek, J.
DC drives are more and more used drives in engineering for both high and low powers. In examination of its dynamic properties one must consider both disturbances of drives themselves and its control and possible disturbances in gears.
Use of comlex dynamic models in design and control of walking robots
Grepl, Robert ; Ondrůšek, Č. ; Kratochvíl, Ctirad
The paper describes the design of complex dynamic model of quadrupedwalking mobil robot. Method of building of thenumerical computational model and its simulating is shown. Complex model consist ofsubmodels of robotic mechanism, DC motor, gearbox model and thermal model ofelectrical motor. In the paper is also discussed application of computational model directly for control ofrobot and also as a data generator for global and local approximation method,mainly artificial neural networks. Control algorithm is also considered in model.
