In recent years, Vejdirektoratet has decided that all suppliers of road signs in Denmark, shall acquire certifications as per the European Conformity regulations. As a part of the CE approval process, all road signs shall be designed according to DS/EN 12899.
Skilte eXpressen produces and distributes road signs in any size and shape. All road signs consist of aluminum plates with a reflective membrane printed to the plates. The sign plates are riveted to an aluminum frame, that can be mounted on any type of mast, or foundation.
Our role in the project, was to develop a full FE model of a standard sign plate, and to document the modeling procedure, to form basis of future designs. Our preferred FE modeling software is Abaqus from SIMULIA, which is a versatile FE package, where almost any physical problem can be solved. Since almost every road sign is unique in terms of dimensions, extra care was taken, to develop an FE model/technique that quickly can be adapted to various geometries, in order to minimize time spent on modelling in the future.
Skilte eXpressen has received a CE approval, and is now certified to sell and distribute road signs in Denmark for many years to come.
