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. Robust design provides high level of design results in the first attempt and design structures insensitive of service conditions variation. Axiomatic method in connection with robust design gives possibility for design parameters definition using various design constraints. The article has intention to present and analysed relations between these methods and approaches. The case study of power transmission (PT) components is carried out in order to present efficiency of the new approaches in design parameters selection and calculation. Reliability, vibrations and noise as design constraints in the stage of the Embodiment design of PT components make conditions for axiomatic method application and robustness provision. Reliability as the design constraint is defined and modelled 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 behaviour 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.
