  1. 26. On Evaluation of Working Conditions aboard High-Performance Marine Craft

    Författare :Pahansen de Alwis; Karl Garme; Anders Rosén; Joakim Dahlman; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-speed marine craft; human factors integration; whole-body vibration; epidemiology; musculoskeletal pain; fatigue; höghastighetsfartyg; human factors; HFI; helkroppsvibrationer; epidemiologi; muskuloskeletal smärta; utmattning; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : High-Performance Marine Craft (HPMC) is a complex system confronted by the stochastic nature of the waves challenging the safety of life at sea. The personnel aboard these craft are vulnerable to detrimental conditions, in fact, limiting the system’s performance evoking the significance of the Human Factors Integration (HFI) in the design and operation of these craft.

  3. 27. Energy absorption and transmission in the hand and arm during high frequency vibration and impact

    Författare :Anna Sörensson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

    Sammanfattning : There has been discussion in international literature as to whether vibration containing impact and high frequencies, i.e. above 1000 Hz could make a special contribution to injuries in the hand and arm. LÄS MER

  4. 28. Towards consonance in working conditions, health and performance aboard high-performance marine craft

    Författare :Manudul Pahansen de Alwis; Karl Garme; Anders Rosén; Stephen Myers; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-speed craft; human factors; whole-body vibration; epidemiology; pain; fatigue; höghastighetsfartyg; mänskliga faktorn; helkroppsvibrationer; epidemiologi; smärta; trötthet; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : The High-Performance Marine Craft (HPMC) is a complex man-machine system dealing with the stochastic nature of the sea. The occupants of these craft are challenged by the strenuous work environments resulting in various detrimental conditions and reducing the overall performance of the system. LÄS MER

  5. 29. Seated postural reactions to mechanical shocks : laboratory studies with relevance for risk assessment and prevention of musculoskeletal disorders among drivers

    Författare :Tobias Stenlund; Börje Rehn; Ronnie Lundström; Ola Lindroos; Fredrik Öhberg; Rolf Moe-Nilssen; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Postural balance; Posture; Electromyography; Musculoskeletal pain; Whole-body vibration; Reliability; Kinematics; Biomechanics; sjukgymnastik; Physiotherapy;

    Sammanfattning : Professional drivers of off-road vehicles, driving on irregular terrain such as in forestry, agriculture and mining, are exposed to whole-body vibration and mechanical shocks. These driver groups have reported severe musculoskeletal problems in the spine, but the association to seated postural reactions is not fully understood. LÄS MER

  7. 30. Procedure for the reduction of the effect of transient whole body vibrations

    Författare :Peter Jönsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

    Sammanfattning : There is a growing interest in the topic areas of increased vibration comfort and reduced vibration levels in work vehicles. Legislation, health costs and demands for increased competitiveness are all important motivating factors in this growing interest. LÄS MER
