Design and structural assessment of the application cases

In WP3 (VT), WP4 (CET) and WP5 (JLM) bonded structures for superstructure of ship have been designed, structural analyses have been performed and prototypes have been produced and tested. For CETENA fairing application case (AC1) flexible adhesives are chosen to join an aluminium fairing to a steel bulwark stay as an alternative to welded or bolted connection. For the joining of the aluminium extrusions the Alcan turn spring system developed in truck and bus constructions has been introduced. Compared with welding, the cold assembly with turn spring system and bonding reduced the overall production cost and provided a better surface as well.

At the first design stage easy-to-use rules are invoked for the feasibility study of structural and joint design. Some examples of the application of analytical rules for the joint analysis are found in for JLM AC 1, 6, 7 and 8. For the pre-design of VT AC the loading of joints was analysed analytically. Also for the preliminary design of CETENA AC6 Casing and AC1 Fairing some analytical methods have been applied.
The final design step assessed by component analysis and testing has the goal to prove the structural integration.

A global FE analysis for CETENA AC6 Casing for prescribed loading cases. For the final design of CETENA AC1 Fairing the FE analysis has been performed. Finite element analyses have also been carried out to estimate the joint performance of VT application case. An overview of documents related to the design and structural assessment of application cases is given in document no. 1-14-D-2002-01-1 "Novel Joint Design".
