Design for Vibration Reduction - An Overview of Models for Product Development with Focus on Excitation and Transmission of Vibrations of Technical Systems

摘要

There are many influencing factors on the vibration of technical systems. A model can be built to analyze the relationship between embodiment parameters and vibration. Looking at product models an overwhelming number of models exists to investigate the embodiment function relation. To support the product developer in designing the vibration of systems the following research question will be examined in this paper: What kind of models can be used to model the relation between embodiment and vibration with the aim to design a system with required vibrations? In order to influce vibrations, the excitation and the transmission of the vibrations can be influenced by the product developer. Therefore, this paper also adresses the following research question: Which models distinguish between embodiment paramters that excite vibrations and embodiment parameters that transmit vibrations? Based on a literature review relevant models for the investigation of the relation between embodiment parameters and vibrations were identified. The focus of the literature search was on models that have been published in the last ten years in the state of research. Categories for the evaluation and classification of the identified models were developed from the state of research on vibration analysis and models. The 15 identified models were evaluated and classified in a matrix using the developed categories. It is noticeable that, with one exception, in all models identified no distinction is made between parameters that cause vibrations and parameters that transmit vibrations. Also different frequency ranges are only considered in a part of the models. In summary, it can be said that there are models that map the relationship between embodiment parameters and vibrations. However, the investigation has shown that the models should be further developed in following research projects regarding the subdivision into excitation and transmission of vibrations and the consideration of different frequency ranges.
