Abstract:
Actual approaches in technical systems design understand horizontal integration of various scientific and technological knowledge and various market and user needs in harmony with human environment. The first part of opening lecture going to introduce audience with this multidisciplinary approach in product development. The farther presentation will contain the case study of power transmission (PT) components of various mechanical structures in order to present efficiency of the new approaches in design parameters selection and calculation. In the future progress of technical systems it is impossible to avoid the power transmission (PT) components. Mechatronic technical systems will include the innovated PT components with high-level quality indicators. The article proposes the application of the new approaches to those components design in order to challenge innovation and inventions. The main objective is to define the design parameters in terms of reliability, vibration and noise as design constraints in the stage of the Embodiment design of PT components. Robust design is provided by using the axiomatic method in this way. Reliability as the design constraint of PT components is defined and modeled in a specific way suitable for this purpose and application. Also, the model of gear vibrations and gear units noise generation is presented in a new way suitable for applying as the design constraint. Those design constraints provide design parameters definition in an efficient way, with high-level service quality indicators. The presented models are based on a great volume of experimental data about service conditions probability, gear and bearing failure probability, gear units vibration and modal behavior etc. Theoretical knowledge and models are insufficient yet to provide the necessary data. The article contains presentation of testing methods and data processing oriented to provide data necessary for the application in the suggested approach to PT components design
