  1. 41. Light-weighting Methodology in Rail Vehicle Design through Introduction of Load Carrying Sandwich Panels

    Författare :David Wennberg; Sebastian Stichel; Per Wennhage; Ragnar Larsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sandwich panels; rail vehicle; lightweight; optimisation; carbody; Vehicle engineering; Farkostteknik; Construction engineering; Konstruktionsteknik; Construction materials; Konstruktionsmaterial;

    Sammanfattning : Lightweight design in rail vehicles has been important for quite some time. Structures have been optimised to fulfill their purpose and cut unnecessary weight to reach allowable axle loads. Classically this is done by using steel, thin-walled structures, throughout the car body, or, alternatively, power-pressed aluminum profiles. LÄS MER

  3. 42. Selection and use of engineering design methods using creative problems solving principles

    Författare :Belinda López-Mesa; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Aided Design; Datorstödd maskinkonstruktion;

    Sammanfattning : Many modern products require the careful planning of a vast number of aspects of their life cycle to succeed in the market, such as, financing, functionality, quality, reliability, environmental impact, manufacturing process, relationship with suppliers, etc. Potentially, the numerous domain- independent design methods generated for decades in the fields of engineering design and creative problem solving (CPS) have much to offer in today's complex multi-objective product design activity.

  4. 43. Squeak and Rattle Prediction for Robust Product Development

    Författare :Mohsen Bayani; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; simulation; product development; squeak and rattle; sound quality;

    Sammanfattning : Squeak and rattle are nonstationary, irregular and impulsive sounds that happen inside the car cabin. For decades, customer complaints about squeak and rattle have been, and still are, among the top quality issues in the automotive industry. LÄS MER

  5. 44. Physically based constitutive models for crash of composites

    Författare :Sergio Costa; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Crushing; FEA; friction; damage mechanics; CDM; kinking;

    Sammanfattning : The transportation industry and passenger cars in particular are strong emitters of gases that contribute to the climate crisis. For this reason, the automotive industry investigates opportunities to reduce emissions, such as reducing the weight of the car. LÄS MER

  7. 45. Affordable automation for airframe assembly : developing of key enabling technologies

    Författare :Henrik Kihlman; Mats Björkman; Giorgos Nikoleris; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Building aircraft is a challenging field. An aircraft has a life expectancy of 40 years, compared to just 10 years for a car. Given the vibrations of flying at close to Mach one at an altitude of 10,000 meters, these machines must function flawlessly in a tough environment. This demands high quality in the assembly processes. LÄS MER
