2. 1. On Drive Force Distribution and Road Vehicle Handling - A Study of Understeer and Lateral Grip

   Author : Matthijs Klomp; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; drive force distribution; drive force; vehicle handling; lateral grip; understeer; acceleration; steady-state cornering; vehicle dynamics; combined slip;

   Abstract : Computer controlled vehicle sub-systems aimed to support drivers in various drivingsituations are rapidly increasing in number and sophistication. These systemshave evolved from anti-lock braking and traction control systems, to electronic stabilitycontrol. READ MORE

4. 2. Longitudinal Force Distribution and Road Vehicle Handling

   Author : Matthijs Klomp; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ehicle dynamics; quasi steady-state; drive force; combined grip; longitudinal force distribution; combined slip; vehicle handling; optimization;

   Abstract : The distribution of longitudinal forces has a large influence on vehicle handling characteristics such as the driver/vehicle interaction, road holding and yaw stability, in particular during combined traction/braking and cornering near the grip limit of the tires. In order to select and develop suitable driveline systems and associated active control that provide consistent driver/vehicle handling, maximum road holding and sufficient yaw stability margins, it is essential to understand the influence of a particular drive force distribution on these handling characteristics.

5. 3. Reconstructing force from harmonic motion

   Author : Daniel Platz; David B. Haviland; John E. Sader; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oscillator; force spectroscopy; atomic force microscopy; intermodulation; multifrequency; inverse problem; high quality factor;

   Abstract : High-quality factor oscillators are often used in measurements of verysmall force since they exhibit an enhanced sensitivity in the narrow frequencyband around resonance. Forces containing frequencies outside this frequencyband are often not detectable and the total force acting on the oscillatorremains unknown. READ MORE

6. 4. On the Load Distribution and Design of a Chain Drive

   Author : Ingvar Troedsson; Maskinelement; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tension force; tensioner; oscillation; chain drive; vibration; load distribution; Mechanical engineering; hydraulics; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

   Abstract : Three methods are presented to calculate the load distribution in a chain drive containing two sprockets and one chain. The rollers, which are in contact with the sprockets, can move along the tooth flanks and their positions are given by force equilibrium. READ MORE

7. 5. Investigating nano-scale viscous and elastic forces withintermodulation : Studies in multifrequency atomic force microscopy

   Author : Per-Anders Thorén; David B. Haviland; Greg Haugstad; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Atomic Force Microscopy; Nonlinear dynamics; Soft materials; High- speed friction measurements; Modeling and numerical simulations; Fysik; Physics;

   Abstract : Investigating visco-elastic forces at the nanometer-scale is important to thecharacterization of soft materials. A quantitative force measurement can be ob-tained using an atomic force microscope (AFM) with a calibrated force transducer(the AFM cantilever). READ MORE
