Optimization Methods for Minimizing Vibrations and Noise Radiation of Gearboxes

摘要

The paper will present our successful results of the effective implementation of the engineering Design Science (DS) knowledge into the process of the engineering design of optimized gear systems (GS) from the point of view of their dynamic behaviour. The new strategies and approaches to the effective implementation of some methods, improved by use of the Theory of Technical Systems, allow the mathematical modeling of the elementary shaft assembly with transmission gear wheels and their definitions on the completely new base of designing of the GS. The new philosophy supports very effectively an optional combination of intuitive, methodical-empirical and flexible systematic strategy of thinking. We have focused especially on the third highest hierarchical level (LIII) of use of engineering design knowledge i.e. on "Flexible systematic strategy based significantly on system of structured knowledge" which optimally supports the creativity of engineering designers. Any technical product is required to fulfill many properties; therefore pursuit of multicriterial optimization is the non-trivial issue. In this case the use of the LIII is very helpful, providing better support for keeping requested "direction" to "goal" states of properties and simultaneously keeping "balance" of their "goal" states when are designing the new technical products (in this case gearboxes).
