2. 21. A Vibro-Acoustic Study of Vehicle Suspension Systems : Experimental and Mathematical Component Approaches

   Author : Eskil Lindberg; Nils-Erik Hörlin; Peter Göransson; Henry Rice; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustics; Vehicle suspension; Disc brake; Wheel rim Roughness noise; Interior tyre-road noise Component mode synthesis; Undeformed coupling interface;

   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

4. 22. On Contact Mechanisms and Mechanical Transmission Performance

   Author : Lars Maclennan; Maskinelement; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik; hydraulics; Mechanical engineering; artificial neural network; experimental study; disc brake; dynamic analysis; shaft; Spur gear;

   Abstract : This thesis consists of four papers, which treat the modelling of a spur gear set and a disc brake, and the interaction between the machine elements. Features of the performance are studied in relation to the initial stated assumptions. READ MORE

5. 23. Numerical and Experimental Investigations on Aerodynamic and Thermal Aspects of Rotating Wheels

   Author : Alexey Vdovin; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ventilation resistance; wind tunnel; brake cooling; ride height; aerodynamic moment; CFD; rim design; vehicle aerodynamics;

   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

6. 24. On the interaction between driver assistance systems and drivers in situations of system failure

   Author : Josef Nilsson; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adaptive cruise control; Chalmers driving simulator; automotive safety; controllability; driver assistance systems; functional safety; dependability; brake failure; fault injection;

   Abstract : The level of automation is increasing in road vehicles as driver assistance systems take control of both speed and steering. Benefits of this development are expected in the form of improved safety, driver comfort, traffic efficiency, etc. READ MORE

7. 25. Safe Transitions to Manual Driving From Faulty Automated Driving System

   Author : Josef Nilsson; RISE; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Driver takeover; functional safety; automated driving; safety; vehicle automation; driver capability; brake failure; controllability; driving simulator.;

   Abstract : This thesis presents a method to assess the safety of transitions from automated to manual driving when vehicle automation fails. The method is based on contributions to the understanding of human driving behavior, also presented in this thesis. READ MORE
