    Abstract : The Life Cycle Energy Optimisation (LCEO) methodology aims at finding a design solution that uses a minimum amount of cumulative energy demand over the different phases of the vehicle's life cycle, while complying with a set of functional constraints. This effectively balances trade-offs, and therewith avoids sub-optimal shifting between the energy demand for the cradle-to-production of materials, operation of the vehicle, and end-of-life phases.

  5. 8. Investigation of Aerodynamic Resistance of Rotating Wheels on Passenger Cars

    Author : Alexey Vdovin; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wheel forces; ventilation resistance; rim design; aerodynamic moment; wheel aerodynamics;

    Abstract : With the current conditions of rising fuel prices and the toughening of environmental legislation for CO2 and other emission gases, vehicle manufacturers around the world are looking into the ways to make their vehicles more energy efficient and therefore more environmentally friendly. One of the ways to achieve this goal is to improve aerodynamic design of vehicles in order to decrease aerodynamic resistance forces. READ MORE

  6. 9. Assessment of crosswind performance of buses

    Author : Magnus Juhlin; Annika Stensson Trigell; Carsten Proppe; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; crosswind; buses; steering feel; directional stability; subjective; objective; aerodynamic load; Vehicle engineering; Farkostteknik;

    Abstract : When driving a vehicle on the road, the driver has to compensate continuously for small directional deviations from the desired course due to disturbances such as crosswinds, road irregularities and unintended driver inputs. These types of deviations have a tiring effect on the driver and should therefore be minimised. READ MORE

  7. 10. Unsteady aerodynamic effects on the driving stability of passenger vehicles

    Abstract : The passenger car is a vital part of modern society, giving people the freedom of flexible travel. As technology advances, customers increase their demand for future products. The automotive industry must therefore adapt to society's requirements for energy-efficient travel, where developing low-drag vehicles is key. READ MORE
