  1. 6. Vehicle dynamic analysis of wheel loaders with suspended axles

    Författare :Adam Rehnberg; Annika Stensson Trigell; Lars Drugge; Peter Eriksson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hjullastare; arbetsmaskin; fordonsdynamik; fordonsteknik; Vehicle engineering; Farkostteknik;

    Sammanfattning : The wheel loader is a type of engineering vehicle used primarily to move crude material over shorter distances. As the vehicle is designed without wheel suspension, wheel loader drivers are exposed to high levels of whole body vibration which influences ride comfort negatively. LÄS MER

  3. 7. Integration of engineering analysis information in the product development process

    Författare :Ma Haoxue; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Sammanfattning : Keen competition in modern industry motivates companies to produce better products in shorter lead-time. In addition low cost is another key factor that leads commercial success of a product. In the last decade, rapid development and implementation of computer technologies have had great impact on the product development process. LÄS MER

  4. 8. Injury Biomechanics in Car-Pedestrian Collisions: Development, Validation and Application of Human-Body Mathematical Models

    Författare :Jikuang Yang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; impact biomechanics; car; mathematical dynamic model; pedestrian; safety countermeasure;

    Sammanfattning : The aim of this study was to develop and validate human-body mathematical models which can be used to simulate the dynamic responses of pedestrians in a car impact. The main focus has been on simulations of bumper impact to the lower extremities, since lower extremity injuries most frequently occur in car-pedestrian accidents and result in long-term consequences and high social costs.

  5. 9. Modelling and laboratory investigations on freight wagon link suspensions with respect to vehicle-track dynamic interaction

    Författare :Per-Anders Jönsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; railway; freight wagon; running gear; link suspension; laboratory test; ; Other engineering mechanics; Övrig teknisk mekanik;

    Sammanfattning : The link suspension is the most prevailing suspension system for freight wagons in central and western Europe. The system design is simple and has existed for more than 100 years. However, still its characteristics are not fully understood. LÄS MER

  7. 10. Simulation of track settlement in railway turnouts-An iterative approach

    Författare :Xin Li; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; track settlement; Railway switch and crossing; cyclic loading; visco-plasticity; vehicle‒track interaction; 3D finite element analysis; granular material; ballast;

    Sammanfattning : In this thesis, a methodology for simulation of track settlement in railway turnouts (switches andcrossings, S&C) is presented. The methodology predicts the accumulated settlement for a given setof traffic loads using an iterative and cross-disciplinary procedure. LÄS MER
