2. 16. Multiobjective Optimisation and Active Control of Bogie Suspension

   Author : Milad Mousavi Bideleh Seyed; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; global sensitivity analysis; Bogie; active control.; robustness analysis; suspension system; multiobjective optimisation;

   Abstract : Railways provide fast, safe, clean, and cheap transportation service. The cost efficiency inrailway operations can be scrutinized from different perspectives. READ MORE

4. 17. Vehicle dynamic analysis of wheel loaders with suspended axles

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

   Abstract : 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. READ MORE

5. 18. Multi-objective optimization of railway bogie suspension damping

   Author : Albin Johnsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railway vehicle dynamics; Bogie suspension design; Multi-objective optimization; Pareto optimized bogie primary and secondary suspensions damping;

   Abstract : In this thesis multi-objective optimization is used to find Pareto fronts showing the set of optimized damping parameters of primary and secondary bogie suspensions. Special interests are put on requirements to enhance safety and comfort of a railway vehicle. READ MORE

6. 19. Suspension design for off-road construction machines

   Author : Adam Rehnberg; Lars Drugge; Annika Stensson Trigell; David Crolla; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; construction machine; engineering vehicle; earth mover; wheel loader; vehicle dynamics; vehicle engineering; whole body vibrations; off-road vehicle; anläggningsmaskin; entreprenadmaskin; hjullastare; fordonsdynamik; fordonsteknik; helkroppsvibrationer; terrängfordon; Vehicle engineering; Farkostteknik;

   Abstract : Construction machines, also referred to as engineering vehicles or earth movers, are used in a variety of tasks related to infrastructure development and material handling. While modern construction machines represent a high level of sophistication in several areas, their suspension systems are generally rudimentary or even nonexistent. READ MORE

7. 20. Towards adaptive bogie design

   Author : Milad Mousavi Bideleh Seyed; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sensitivity analysis; Optimization; suspension system; bogie; active control;

   Abstract : Suspension components play a crucial role in bogie dynamics behavior. In this regard, passive and active systems are developed to meet various design requirements. Adaptive suspension systems can adjust the bogie dynamics with respect to different operational scenarios and as a result improve the vehicle performance. READ MORE
