“…The most widely used modelling approach to capture this last effect is due to Archard, where the wear is described as proportional to the load and the sliding distance [31]. Several works have subsequently appeared that use Archard's model or a slight variation of it, depending on the application at hand [32], [33], [41]. In this work, an innovative approach which takes into account also the stochastic nature of the wear dynamic is proposed, with the advantage that it can be directly extracted from conventional tests carried out during anti-skid system design and testing.…”

In ground vehicles, braking actuator degradation and tire consumption do not represent a significant maintenance cost as the lifespan of both components, at least in common situations, is rather long. In the aeronautical context, and for aircraft in particular, instead, braking actuator degradation and tire consumption significantly contribute to an aircraft maintenance cost due to the frequency of their replacement. This is mainly due to the fact that aircraft braking maneuvers last significantly longer than those in the automotive context. So that the anti-lock braking system is always active during the braking maneuver, making its impact on the consumption of the two components significant. This work proposes an innovative datadriven model of brake and tire degradation, showing how they are related to the anti-skid controller parameters. The analysis is carried out in a Matlab/Simulink environment on a single wheel rigid body model, validated experimentally, which includes all the nonlinear effects peculiar of the aeronautic context. The results show that by using an appropriate anti-skid control approach, it is possible to directly regulate the consumption of these components while at the same time guaranteeing the required braking performance.

“…The friction between a braking pad and the disk results in the wear of both components. In this paper, the wear of pad material is modelled according to a generalized form of Archard's law, which can be expressed in cylindrical coordinates as [12,13]:…”

A rapidly shifting market and increasingly stringent environmental regulations require the automotive industry to produce more efficient low-emission Eletric Vehicles (EVs). Regenerative braking has proven to be a major contributor to both objectives, enabling the charging of the batteries during braking and a reduction of the load and wear of the brake pads. The optimal sizing of such systems requires the availability of good simulation models to improve their performance and reliability at all stages of the vehicle design. This enables the designer to study both the integration of the braking system with the full vehicle equipment and the interactions between electrical and mechanical braking strategies. This paper presents a generic simulation framework for the identification of thermal and wear behaviour of a mechanical braking system, based on a lumped parameter approach. The thermal behaviour of the system is coupled back to the friction coefficient between the pad and the disk to assess its effect on braking performance. Additionally, the effect of wear and temperature on the generation of airborne particles is investigated. Subsequently, experimental data collected on a real EV is used to validate and tune the previously described simulation model, following a proposed validation procedure. The instrumentation method and challenges, as well as the experimental procedure used to collect the data on a chassis dynamometer and in real-world driving conditions, are described. Finally, simulation results for different driving scenarios are used to compare virtual and experimental results.

“…Therefore, this approach is often assigned to Archard and will be referred to as the Archard model in the following. The Archard approach is of great importance for the numerical calculation of tool wear and is commonly used for this purpose in the original version or in further developed versions [15].…”

Tools are of strategic importance for industrial manufacturing processes. Their behaviour has a great influence on the productivity of the process and the quality of the product. A material saving and efficient technique for processing metallic workpieces is cold forging. One major challenge of this production method is the handling of high contact normal stresses in the tool contact, which can lead to severe tool wear. To investigate promising approaches for understanding wear modelling and wear reduction a demonstrator process based on the first stage of a total five-staged cold forging process for the manufacturing of a bolt anchor is considered in the scope of this research. This work aims at the further development of a numerical wear calculation based on an adapted Archard model in order to be able to realistically predict the tool wear in cold forging processes. Therefore, the material characterization of the used workpiece material as well as an investigation of the worn tool dies takes place to validate a numerical wear calculation model. Furthermore, this research addresses a reduction in wear by identifying critical areas and changing the inlet geometry of the investigated demonstrator tool die. This way, conclusions can be drawn about the wear sensitivity during numerical process design, and particularly critical areas can be geometrically modified in terms of the design.
