  2. 1. Concept evaluation and contact problems in simple rotordynamical systems

    Author : Magnus Karlberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Abstract : Rotating machines serves an important role in many different applications. Extensive research has been made, manly during the last century, in order to develop these systems and understand the dynamics. The theory of rotordynamics differs in many fundamental aspects from structural dynamics and is therefore usually treated as an own research area. READ MORE

  5. 3. Coupled vibrations in horizontal and vertical rotor-bearings systems

    Author : Jean-Claude Luneno; Magnus Karlberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technology - Engineering mechanics; Teknikvetenskap - Teknisk mekanik; Hållfasthetslära; Solid Mechanics;

    Abstract : For dynamical systems having several degrees of freedom, motion in one direction can induce motion in the other and/or vice versa. This means that there is a certain coupling between these two motions. Coupling can in some cases be a source of instability that causes self-excited vibrations in rotating machinery. READ MORE

  6. 4. The Chorda Tympani Nerve : Role in Taste Impairment in Middle Ear Disease and after Ear Surgery

    Author : Katarina Berling Holm; Magnus von Unge; Mikael Karlberg; Uppsala universitet; []
    Keywords : Chorda tympani nerve; ear surgery; taste; chronic suppurative otitis media; otosclerosis; electrogustometry; filter paper disc method; quality of life; transmission electron microscopy; degeneration; sprouting; Surgery; Kirurgi;

    Abstract : The chorda tympani nerve, also known as the taste nerve, runs uncovered through the middle ear cavity, a localization that exposes the nerve to pathological processes and surgical trauma in the middle ear. People operated on for otosclerosis tend to complain more about postoperative taste disturbances than those operated on for chronic otitis media. READ MORE

  7. 5. Data Driven Condition Monitoring for Transmission and Axles

    Author : Elisabeth Källström; John Lindström; Magnus Karlberg; Jiri Tuma; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Abstract : As the requirements to improve up-time and thus to reduce costly down-time con-tinuously increases, the construction equipment business focuses on more and newways to increase ability and sensitivity of early fault detection of critical compo-nents and parts in order to prevent failure. Failure of critical components in theheavy duty machine may lead to unnecessary stops and expensive downtime. READ MORE
