Design of an adjustable centre console system for an 8m highspeedcraft with fatigue analysis of critical mechanisms

Sammanfattning: Today, ergonomic adjusting capabilities are lacking on centre consoles of small high-speed crafts with respect to the crew height. The centre consoles are normally constructed to fit the mean height of the operators to cover as many end users as possible. Issues might therefore arise for the operators who deviate from the mean height. This master thesis report covers the design, implementation and evaluation of a set of mechanisms which are to enable the operator work space of an 8-meter high speed craft to be longitudinally movable as well as ergonomically adjustable for operators with a length 160 to 200 cm, which include more than 90 % of the Swedish population. The resulting design is to make out a part of the Aevotec 800 which is an 8-meter high-speed craft which is being designed by Poseidon Konsult. The development during the project included several phases; a concept phase, feasibility phase and the main design phase. The main design phase contains several cycles which were evaluated based by peak load calculations, fatigue analyses, ISO design calculations, design review/feedback sessions, anthropometrical measurement and mock-up/end-user review. Based on the executed evaluations of the project, a feasible system has been designed capable of handling the requirements set for the project. The superstructure has been successfully designed by ISO 12215-5 and fulfils parts of the DNV-GL regulations regarding ergonomics for high-speed light crafts.
