“…Assuming that the wobble mode occurs independently of the roll mode around the rear axle, the front axle can be simplified as a rigid body with only one degree of freedom, i.e., the rotation around the steering axis ( Figure 1) [16]. Monti et al [41] demonstrated the utility of axiomatic design theory to analyze the critical aspects to aid the design of an innovative architecture for an MRF steering damper fully integrated with the motorcycle steering head. Previous studies have also noted the problem of wear of the sealing components (e.g., excessive swelling or loss of strength) due to contact between seal and the MRF when the fluid is subjected to the magnetic field.…”

Powered-two-wheelers (PTWs) are increasingly popular because of their lower cost compared to cars, and therefore the riders’ exposure risk is increasing. Due to their complex dynamics characterized by high non-linearity and inherent instability, PTWs are more difficult to control compared to four-wheeled vehicles. Wobble is a high-frequency instability mode affecting the steering assembly of the PTW, and which often causes the rider to lose control and crash when it occurs. In this paper, we present the design of a new motorcycle semi-active steering damper integrated into the steering column and utilizing a magnetorheological fluid (MRF) for variable damping torque. An analytical model of the concept was first used to perform the preliminary sizing, followed by concept validation using a 3D FE multiphysics magnetic-fluid analysis. The final innovative design offers several advantages compared to traditional steering dampers: (i) a wide range of adjustable damping torque values, with a multiplication factor up to 10 with a maximum electrical current of 2 A; (ii) total integration into the motorcycle steering column enabled by its axial design and limited radius; (iii) a simple chamber geometry that allows for easy manufacture; (iv) longer seal life due to the absence of direct contact between seals and the MRF.

“…In this context, Axiomatic Design (AD) [11] can be used as a powerful tool to optimize the selective process [12][13][14][15][16]. An interesting application of AD in health care is the optimization of the patient flow in hospitals [17].…”

Axiomatic Selection of Health and Social Care Web Services on the Basis of Use Cases

in recent years remote patient monitoring systems, which are conceived to monitor patient and store the recorded data, employ Service Oriented Architectures (SOA). In health care systems, if on the one hand the SOA features allow enriching the offer of services to patients and their families, on the other hand the problem arises of selecting the most appropriate set of web services for homogeneous groups of users or for each individual clinical case. In this paper, we propose a methodology based on the Axiomatic Design for the composition and selection of web services, which are based on the case stories studied, built using semi-structured interviews to different stakeholders involved in the care process. The proposed methodology detects in a systematic way all functional requirements by taking into account the different stakeholders involved in the process and their interactions. Thus, it identifies the interested actors for a specific health protocol, and consider all information to be exchanged and the Web Services to be implemented. The development of this methodology opens interesting scenarios even in areas not currently affected by such systems, such as health and safety at work for monitoring patients with chronic illnesses or for their work reintegration following acute clinical events. A specific case study is considered in order to illustrate the proposed approach.

“…The IAMS method is a good selection process from the translation of the customer needs into the technical requirements and then to obtain the ranking of the design alternatives. One alternative approach to obtain the ranking of the design alternative is based on Axiomatic Design (i.e., a structured method to identify optimal solution applied in a wide range of scientific and industrial environment [6][7][8][9][10][11]). Using this method, some specific approaches for MADM algorithm have been developed.…”

In the mechanical design, the selection among material alternatives has become a pressing issue due to the progressive growth in the complexity of mechanical systems, in search of continuous increase in performance and the presence of a wide range of possible materials. Moreover, there are many requests for projects, and this makes the choice of material a decisive activity for the success or failure of the project itself. This paper makes a comparative evaluation of two important approaches to identify the best materials alternatives: the C-VIKOR and the Fuzzy Axiomatic Design. The work considers as a case study the selection of the material for the production of the valve seats in a highperformance engine. An evaluation of the results obtained is made to show the peculiarity of each of the two approaches.
