Original Abstract

Řízené pohonové soustavy dnes představují technické soustavy se složitou strukturou, tvořenou subsoustavami různé fyzikální podstaty a se složitými strukturami zpětných vazeb. Tyto skutečnosti, v kombinaci s nelinearitami a případně i stochastickými složkami, obsaže-nými v budících procesech, vedou k situaci, že výpočty se stávají často velmi náročnými. Zvláště pak v těch případech, kdy analyzujeme přechodové stavy nebo když hodnotíme odezvy pohonových soustav na poruchy.

English abstract

Todays requirements on drive design essentially differs from require-ments usual in the past. Firstly the requirements on operating effects appears during the design phase and so called “complex” modeling, modeling “in alterna-tives” with the emphasis on design influence on the environment starts to enforce. Dynamic and stress/strain analysis (even the complex ones) become common rutines and provision of operating reliability for the specified period analyzed structure technical life become the priority. What are the sources of current requi-rements on new drive systems development? Let us list at least the basic ones : - more and more complex development cycle, reflecting new technical, technological, ecological and other requirements, - overlapping the particular phases during design, preparation and production introduction stage with the aim to reduce the time necessary for new system development as much as possible, - requirements on properties and behavior of designed system are often changed during the design stage as the effect of fast innovative cycles or as the effect of science and technology development. The contribution shows how to solve mentioned problems during the analysis of particular technical systems with tooth wheels and gears. To model and simulate such systems it is necessary : - to create objective structured model of basic mechanical structure, - to create at least simplified models of meshing conditions, transfer function and kinematic excitation for tooth wheels and gears, - to create model of surrounding environment, - to formulate the concept of drive system control and - to propose the way of integration of basic drive structure, surrounding environment and control.
