The demand for short term energy storage providing high power for electric and hybrid-electric vehicles is increasing dramatically. Stationary flywheel energy storage systems (FESS) are established as uninterruptible power supply (UPS) and represent an emerging market. In contrast, mobile FESS are currently only used in few applications such as motor sports. To enable a wider use in personal and public transportation the lifespan of the flywheel's bearings needs to be increased significantly. This paper presents an alternative approach to extend the lifespan of the flywheel's bearings by using a combination of rolling element and active magnetic bearings (CREAMB).

The demand for short term energy storage providing high power for electric and hybrid-electric vehicles is increasing drastically. Stationary FESS （flywheel energy storage systems） is established as UPS （uninterruptible power supply） and represent an emerging market. In contrast, mobile FESSs are currently only used in a few application, e.g., in motor sports. To enable a wider use in personal and public transportation the life-span of the flywheel＇s bearings needs to be increased significantly.

The trend of sharing concepts is constantly increasing, whether for economic or environmental reasons. Consequently, there is numerous scientific research work addressing the subject of sharing concepts. Many of these works deal with questions on the topic of sharing concepts itself, however, much less research has been done on the question of how a sharing concept can be developed in the very first place. Regarding the sectors studied, it is noteworthy that while automotive and bike sharing concepts are studied intensively, agriculture and farming remains rather in the background. Objective. The purpose of this publication is to systematically use systems engineering methods to develop a sharing concept for heavy duty agricultural vehicles. Thereby, the focus of this publication is on the consideration of technical aspects. methods. Due to the multidisciplinary complexity of the sharing concept, a method from the field of Model-Based Systems Engineering, ARCADIA is chosen. Using this method, the development of the Sharing Concept is systematically demonstrated: Starting from the abstract Operational Analysis, stakeholders and their interactions are identified. In the System Analysis, similar to SysML, diagrams are used to represent both structures and behaviour models. In the Logical Architecture, the internal relationships between the system components are ***. Using the methodical, systematic, and structured procedure according to the ARCADIA method, it was possible to analyse the method's individual levels. On ARCADIA's top, most abstract level, an Operational Analysis was carried out to identify the key stakeholders of the sharing concept. The next level, the Systems Analysis, showed that a sharing model for compost turners has to be divided into three main processes: 1.) Data Acquisition and Data Preparation, 2.) Location Planning and 3.) Route Planning. These processes were examined in detail in the Logical Analysis, paying particular attention
