1. Investigation of Aerodynamic Resistance of Rotating Wheels on Passenger Cars
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

2. Wheel Modelling and Cooling Flow Effects on Car Aerodynamics
Abstract : In recent years, the automotive industry has focused on computer simulations as an alternative to physical testing. This allows for early vehicle optimization, short turn around times, and significant cost savings. READ MORE

3. Effect of Temperature on Mechanical Properties of Railway Wheel Steels
Abstract : One of the most important aspects in railway operation is the interaction between rail and wheel. The contact conditions give rise to wear and damage in both components. Medium carbon steels are used in these components due to their combination of high strength and good wear properties in relation to cost. READ MORE

4. A Vibro-Acoustic Study of Vehicle Suspension Systems : Experimental and Mathematical Component Approaches
Abstract : The objective of the present work is to study the vehicle suspension as a vibro-acoustic system of high complexity, consisting of many sub-systems with fundamentally different acoustical properties. In a parallel numerical and experimental modelling effort, important contributions to the understanding of its behaviour have been achieved. READ MORE

5. Numerical and Experimental Investigations on Aerodynamic and Thermal Aspects of Rotating Wheels
Abstract : With todays and future environmental legislations for CO2 and other emission gases, all vehicle manufacturers are forced to further develop tools and methods to make their vehicles more energy efficient and environmentally friendly. One option to achieve this is to reduce the aerodynamic resistance since it has a significant influence on the vehicle fuel consumption, especially for velocities higher than 50 km/h. READ MORE
