1. 1. Modeling of planing craft in waves

   Författare :Karl Garme; Dan Zenkert; Richard Akers; KTH; []
   Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydraulic engineering; marine; ocean; Planing craft; time-domain simulation; design loads; Vattenteknik; Water engineering; Vattenteknik;

   Sammanfattning : Simulation of the planing hull in waves has been addressed during the last 25 years and basically been approached by strip methods. This work follows that tradition and describes a time-domain strip model for simulation of the planing hull in waves. The actual fluid mechanical problem is simplified through the strip approach.

3. 2. Loads and responses for planing craft in waves

   Författare :Anders Rosén; Dan Zenker; Brian Hayman; KTH; []
   Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

4. 3. On Structural Design of High-Speed Craft

   Författare :Mikael Razola; Jakob Kuttenkeuler; Anders Rosén; Olav Fredrik Rognebakke; KTH; []
   Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

5. 4. 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 :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

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

   Författare :Mikael Razola; Anders Rosén; Ermina Begovic; KTH; []
   Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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
