  2. 1. Controlling over-actuated road vehicles during failure conditions

    Author : Daniel Wanner; Annika Stensson Trigell; Lars Drugge; Mats Jonasson; Jochen Rauh; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vehicle dynamics; vehicle safety; driver-vehicle interaction; failure analysis; wheel hub motor failure; over-actuation; fault-tolerant control; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : The aim of electrification of chassis and driveline systems in road vehicles is to reduce the global emissions and their impact on the environment. The electrification of such systems in vehicles is enabling a whole new set of functionalities improving safety, handling and comfort for the user. READ MORE

  4. 2. On Energy Efficient Mobile Hydraulic Systems : with Focus on Linear Actuation

    Author : Kim Heybroek; Petter Krus; Jan-Ove Palmberg; Torben Ole Andersen; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In this dissertation, energy efficient hydraulic systems are studied. The research focuses on solutions for linear actuators in mobile applications, with emphasis on construction machines. Alongside the aspect of energy efficiency, the thesis deals with competing aspects in hydraulic system design found in the development of construction machines. READ MORE

  5. 3. On-Engine Turbocharger Performance Considering Heat Transfer

    Author : Habib Aghaali; Hans-Erik Ångström; Jose R. Serrrano; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbocharger; Internal combustion engine; heat transfer; turbocharged engine; on-engine turbocharger; turbocharger performance; توربو شارژر، موتور احتراق داخلی، انتقال حرارت، توربوچارجر; turbo; turboladdare; förbränningsmotor; värmeöverföring; turboladdad motor;

    Abstract : Heat transfer plays an important role in affecting an on-engine turbocharger performance. However, it is normally not taken into account for turbocharged engine simulations. READ MORE

  6. 4. Reduction of Audible Noise of a Traction Motor at PWM Operation

    Author : Hanna Amlinger; Ines Lopez Arteaga; Siv Leth; Wolfgang Kropp; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electromagnetic noise; pulse width modulation PWM ; switching frequency; traction motor; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : A dominating source for the radiated acoustic noise from a train at low speeds is the traction motor. This noise originates from electromagnetic forces acting on the structure resulting in vibrations on the surface and thus radiated noise. It is often perceived as annoying due to its tonal nature.

  7. 5. On Noise Generation and Dynamic Transmission Error of Gears

    Author : Mats Henriksson; Leping Feng; Reader Andy Moorhouse; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicle engineering; Farkostteknik; Acoustics; Akustik;

    Abstract : Noise from heavy trucks is an important environmental issue. Several sources contribute to the total noise level of a vehicle, such as the engine, gearbox, tires, etc. The tonal noise from the gearbox can be very disturbing for the driver, even if the noise level from the gearbox is lower than the total noise level.
