Neural network-based models for a vibration suppression system equipped with MR brake
2012
This paper is devoted to the modeling and simulation of a full-scale commercially available magnetorheological (MR) brake installed in a semi-active suspension (SAS) system. The analysis of the Bouc-Wen and Dahl mathematical models of MR damper is presented. Influence of their parameters on the response is explored. Subsequently, by using the neural networks, the parameters characterizing each model are estimated. This makes it possible to perform the comparative analysis of the suggested damper models responses with the measured experimental results. The novelty of the presented methodology is the application of artificial intelligence methods to estimate model parameters of a MR brake uti…
A regenerative braking system for internal combustion engine vehicles using supercapacitors as energy storage elements - Part 2: Simulation results
2020
Abstract In this two-part work, an electric kinetic energy recovery system (e-KERS) for internal combustion engine vehicle (ICEV) is presented and its performance evaluated through numerical simulations. The KERS proposed is based on the use of a supercapacitor as energy storage, interfaced to a brushless machine through a properly designed power converter. In Part 1, the system is described and analysed, and the mathematical model used for the simulations is presented. For each component of the KERS, the real efficiency and the power or energy limitations are adequately considered. In Part 2, the energetic and economic advantages attainable by the proposed KERS are evaluated using MATLAB S…

Modeling and improvement of the tricycle braking system for controlled skidding
2021
In the current paper was approached the braking system of tricycles for controlled skidding, which are used by lovers of extreme sports. The complete modeling of such a tricycle has been performed and its braking system has been improved for a great performance and a better controlled braking. Also, simulation tests were performed using the finite element to achieve the best constructive variant of the brake disc.
Les non-publics de la culture. Une approche ethnographique de situations de réception demi-contraintes
2013
Photographic exhibitions are organized today "outdoor"; I study the "non-public" (Ancel & Pessin, 2004): the absents. What are the factors hindering the encounter with the works despite their urban exposure? The article attempts to study the performances of culture that are forged by the respondents (migrants from the lower classes) during outings organized by community centers or municipal associations. To understand why photographic exhibitions fail to mobilize some, I observe in fact that the last prefer other cultural events. Using two case studies (a contemporary dance show, a play), I show that the contact of some actors with culture lead to misunderstandings or misconceptions that me…
