  1. 1. Assessment of crosswind performance of buses

    Författare :Magnus Juhlin; Annika Stensson Trigell; Carsten Proppe; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; crosswind; buses; steering feel; directional stability; subjective; objective; aerodynamic load; Vehicle engineering; Farkostteknik;

    Sammanfattning : When driving a vehicle on the road, the driver has to compensate continuously for small directional deviations from the desired course due to disturbances such as crosswinds, road irregularities and unintended driver inputs. These types of deviations have a tiring effect on the driver and should therefore be minimised. LÄS MER

  3. 2. Ride Comfort Optimization of Buses

    Författare :Peter Eriksson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; structural vibrations; FEM; global optimization; ride comfort; roll control system; MBS; optimization; bus; road irregularities; sensitivity analysis;

    Sammanfattning : As the design of buses is constantly improving, passengers are becoming more fastidious and the demand for a more comfortable travelling environment is constantly increasing. The main objective of this thesis is to contribute to the understanding of how the design of buses affects the ride comfort characteristics. LÄS MER

  4. 3. Steering green buses : The opportunities and challenges of introducing renewable fuel in public transport

    Författare :Malin Aldenius; Miljö- och energisystem; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Public transport; Renewable fuel; Electric buses; Sustainable transport; Green public procurement; Environmental requirements;

    Sammanfattning : The aim of this thesis is to compare and analyse the introduction of renewable fuel in the public transport sector, focusing on the challenges and opportunities encountered by involved stakeholders on the regional and local levels. The results contribute to answering three research questions: 1) How do organisational factors and local and regional contextual factors influence the introduction of renewable fuel? 2) What are the challenges and opportunities of using green public procurement as a policy tool to introduce renewable fuel in the public transport sector? 3) How do the challenges and opportunities regarding the introduction of renewable fuel differ depending on the type of renewable fuel? Four papers are included in the thesis. LÄS MER
