1. What Is Uptis and What Advantages Does It Offer?
Frequently Asked Questions 1. What is Uptis and what advantages does it offer? Uptis (acronym standing for “Unique Puncture-proof Tire System”) is an assembled airless wheel structure. Uptis has been made possible through Michelin’s mastery and expertise with tire mechanics and high-tech materials. It also represents an evolution of Michelin’s expertise in TWEEL technology. Uptis can be thought of as the first in a new generation of airless solutions. This technology for passenger vehicles offers a number of advantages: ▪ Car drivers feel safer and more secure on the road due to the reduced risk of flat tires and other air loss failures that result from punctures or road hazards. ▪ Fleet owners and professional vehicle drivers optimize their business productivity (no downtime from flats, near-zero levels of maintenance). ▪ Raw material use is reduced, which in turn reduces waste. 2. Why do car drivers feel more at ease with Uptis? Uptis is designed to be impervious to traditional tire failures due to air loss. It does not use compressed air. It therefore eliminates the need for regular inflation pressure maintenance. 3. What is the strategy behind Uptis? Uptis represents Michelin’s vision for the future of mobility. Michelin illustrated its vision of sustainable mobility through the Vision concept1, which the Group unveiled at the Movin’On World Summit on Sustainable Mobility in 2017. Uptis shows how Michelin is adhering to its roadmap for research and development, which comprises these four main pillars of innovation: Airless, Connected, 3D-printed and 100% Sustainable (i.e., renewable or bio-sourced materials). -

Lowering Fleet Operating Costs Through Fuel
LOWERING FLEET OPERATING KEY TAKEAWAYS COSTS THROUGH FUEL EFFICIENT Taking rolling resistance, maintenance, TIRES AND RETREADS wheel position and tires, both new and WHAT YOU NEED TO KNOW TO RUN LEANER retread, into account allows companies to maximize fuel efficiency. Author: Josh Abell, PhD • Rolling resistance has a direct and significant correlation to the fuel A retreaded tire can be just as fuel efficient, economy of the vehicle. or even better, than a new tire. • Tires become more fuel efficient as they are worn due to lessened Rolling Resistance: Why it Matters rolling resistance. Rolling resistance is a measurement of the energy it takes to roll a tire on a surface. • Even among new and retread tires For truck tires, rolling resistance has a direct and significant correlation to the fuel claiming to be Smartway certified, economy of the vehicle. Whether you run a single truck or an entire fleet, tire rolling actual rolling resistance will vary. resistance is a crucial element that should be taken into account to minimize fuel costs. Since fuel costs are one of the biggest expenses in trucking operations, as tire rolling resistance decreases, your savings add up. Tire rolling resistance is measured in a lab using realistic and well-established test parameters relied upon by tire/vehicle manufacturers and government regulators. From this testing, original tires and retreaded tires can be quantified by a rolling resistance coefficient, known as “Crr.” The lower the Crr, the better. Studies have shown that a reduction in Crr can result in real-world fuel savings. For example, a 10% reduction in Crr for your truck tires can reduce your fuel consumption by 3%, and lead to savings of $1,000 or more per truck per year.1 © 2017 Bridgestone Americas Tire Operations, LLC. -
Estudio De Un Sistema Aerodinámico Activo En Automóviles: Control Y Automatización Del Sistema
TRABAJO FINAL DE GRADO Grado en Ingeniería Mecánica ESTUDIO DE UN SISTEMA AERODINÁMICO ACTIVO EN AUTOMÓVILES: CONTROL Y AUTOMATIZACIÓN DEL SISTEMA Memoria y Anexos Autor: Antonio Rodríguez Noriega Director: Sebastián Tornil Convocatoria: Junio 2018 Estudio de un sistema aerodinámico activo en automóviles: control y automatización del sistema Resumen A lo largo de este proyecto se tratará el diseño desde cero de un sistema de aerodinámica activa para automóviles. El proceso consta de tres partes diferenciadas: el estudio aerodinámico, donde se caracteriza la interacción fluidodinámica de un perfil alar; el estudio mecánico, donde se diseña el conjunto de mecanismos que forman el sistema mecánico, así como su posterior validación; y la automatización y el control del sistema, donde se modeliza el comportamiento del vehículo y se implementa en un sistema electrónico de control regulado. Estas partes se presentan como tres Trabajos Finales de Grado distintos relacionados entre sí. En esta memoria se desarrolla la tercera de ellas: la automatización y el control del sistema. El objetivo principal ha sido completar la fase de diseño de un sistema que mejore el comportamiento dinámico de un vehículo de carácter deportivo en el mayor número posible de situaciones. Esto se ha conseguido variando la repartición de cargas normales por rueda a partir de la modificación de las características geométricas del propio conjunto aerodinámico, mediante el uso de actuadores lineales regulados por un sistema de control en función de las condiciones del automóvil en tiempo real. I Memoria Resum Durant el transcurs d’aquest projecte es tractarà el disseny des de zero d’un sistema d’aerodinàmica activa per a automòbils. -

The benefits of a 4WD architecture are presented along with the tools for further optimization and understanding. The goal is to provide real, actionable information to teams deciding to pursue 4WD vehicles and quantify the results of difficult engineering tradeoffs. Analytical bicycle models are used to discuss the effect of the Center of Gravity location on vehicle performance, and Acceleration-Velocity Phase Space (AVPS) is introduced as a useful tool for optimization. -

Listed below is a basic outline of the principal points: • Tyres must be suitable* for the vehicle/trailer it is being fitted to and they must be inflated to the correct pressures as recommended by either the vehicle or tyre manufacturer . *Suitability = correct size, correct load specification, speed rating and direction if applicable • No tyre shall have a break in its fabric or cut deep enough to reach or penetrate the cords. No cords must be visible either on the treaded area or on the side wall. No cut must be longer than 25 mm or 10% of the tyre’s section width, whichever is the greater. • There must be no lumps, bulges or tears caused by separation of the tyre’s structure. -

Camber Effect Study on Combined Tire Forces
Camber effect study on combined tire forces Shiruo Li Master Thesis in Vehicle Engineering Department of Aeronautical and Vehicle Engineering KTH Royal Institute of Technology TRITA-AVE 2013:33 ISSN 1651-7660 Postal address Visiting Address Telephone Telefax Internet KTH Teknikringen 8 +46 8 790 6000 +46 8 790 6500 www.kth.se Vehicle Dynamics Stockholm SE-100 44 Stockholm, Sweden Abstract Considering the more and more concerned climate change issues to which the greenhouse gas emission may contribute the most, as well as the diminishing fossil fuel resource, the automotive industry is paying more and more attention to vehicle concepts with full electric or partly electric propulsion systems. Limited by the current battery technology, most electrified vehicles on the roads today are hybrid electric vehicles (HEV). Though fully electrified systems are not common at the moment, the introduction of electric power sources enables more advanced motion control systems, such as active suspension systems and individual wheel steering, due to electrification of vehicle actuators. Various chassis and suspension control strategies can thus be developed so that the vehicles can be fully utilized. Consequently, future vehicles can be more optimized with respect to active safety and performance. Active camber control is a method that assigns the camber angle of each wheel to generate desired longitudinal and lateral forces and consequently the desired vehicle dynamic behavior. The aim of this study is to explore how the camber angle will affect the tire force generation and how the camber control strategy can be designed so that the safety and performance of a vehicle can be improved. -
