2. 1. Lean Prototyping of Multi-body and Mechatronic Systems

   Author : Anders Jönsson; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Major drivers behind increased efforts in product development are the increased competition due to globalisation and the urgent transformation of society towards sustainability. Furthermore, the average product lifetime has been compressed significantly over the last decade. READ MORE

4. 2. On multi body systems simulation in product design

   Author : Petri Makkonen; KTH; []
   Keywords : ;

   Abstract : The aim of this thesis is to provide a basis for efficientmodelling and software use in simulation driven productdevelopment. The capabilities of modern commercial computersoftware for design are analysed experimentally andqualitatively. READ MORE

   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; track irregularities; vehicle response; wheel–rail force; axle box acceleration; Dynotrain; Gröna Tåget; multi-body system; simulations; spårlägesfel; fordonsrespons; hjul–räl-krafter; axelboxacceleration; Dynotrain; Gröna Tåget; flerkroppssystem system; simuleringar; Järnvägsgruppen - Fordonsteknik; Järnvägsgruppen - Fordonsteknik; Vehicle and Maritime Engineering; Farkostteknik; Järnvägsgruppen - Infrastruktur; Järnvägsgruppen - Infrastruktur;

   Abstract : Deviations from the design track geometry are called track irregularities, which are a main excitation mechanism in the track–vehicle dynamic system, and very important to monitor and maintain to have trac on a line run safely and comfortably. Especially during vehicle acceptance testing, it is important that a new vehicle behaves close to design predictions and within limit values, thus it is important to be able to describe track irregularities in a consistent way.

6. 4. Extended Computational Module for Tractive Effort at Rolling and Spinning Point Contacts

   Author : Mikael Törmänen; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spin; thermal effects; Hertzian contact; continuously variable transmission; rolling resistance; speed pole; traction drive; multi-body system; efficient numerical procedure;

   Abstract : One category of mechanical systems that contains power-transferring point contacts is traction drive variators. These variators can be used in different concepts for Continuously Variable Transmissions (CVTs) and in vehicle applications, in order to achieve optimum engine operating conditions leading to improved driveability, reduced fuel consumption and an increase in overall vehicle performance.
