  1. 1. On Structural Design of High-Speed Craft

    Författare :Mikael Razola; Jakob Kuttenkeuler; Anders Rosén; Olav Fredrik Rognebakke; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; slamming; high-speed craft; finite-element analysis; design methods; experimental analysis; numerical simulations; design loads; statistical analysis;

    Sammanfattning : The development in structural design and construction of high-speed craft has been extensive during the last decades. Environmental and economical issues have increased the need to develop more optimized structures, using new material concepts, to reduce weight and increase performance efficiency. LÄS MER

  3. 2. New Perspectives on Analysis and Design of High-Speed Craft with Respect to Slamming

    Författare :Mikael Razola; Anders Rosén; Ermina Begovic; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Slamming; high-speed craft; finite-element analysis; design methods; experimental analysis; numerical simulations; design loads; statistical analysis; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : High-speed craft are in high demand in the maritime industry, for example, in maintenance operations for offshore structures, for search and rescue, for patrolling operations, or as leisure craft to deliver speed and excitement. Design and operation of high-speed craft are often governed by the hydrodynamic phenomena of slamming, which occur when the craft impact the wave surface. LÄS MER

  4. 3. On Evaluation and Modelling of Human Exposure to Vibration and Shock on Planing High-Speed Craft

    Författare :Katrin Olausson; Karl Garme; Jakob Kuttenkeuler; Dominic J. Taunton; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; whole-body vibration; high-speed craft; working conditions; seat modelling; apparent mass; ergonomics; human factors; ISO 2631-1; ISO 2631-5; extreme values; acceleration statistics; slamming;

    Sammanfattning : High speed in waves, necessary in for instance rescue or military operations, often result in severe loading on both the craft and the crew. To maximize the performance of the high-speed craft (HSC) system that the craft and crew constitute, balance between these loads is essential. LÄS MER

  5. 4. Loads and responses for planing craft in waves

    Författare :Anders Rosén; Dan Zenker; Brian Hayman; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Applied mechanics; planing craft; high-speed craft; waves; model tests; sull-scale trials; Teknisk mekanik; Engineering mechanics; Teknisk mekanik;

    Sammanfattning : Experimental and numerical analysis of loads and responses for planing craft in waves is considered. Extensive experiments have been performed on a planing craft, in full-scale as well as in model scale. The test set-ups and significant results are reviewed. LÄS MER

  7. 5. 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
