Easy to replace footstep parts : A new solution for a ingress modul on a truck with high maturitylevel. Research is focused on ergonomic and materialselection. (English)
Abstract [en]

The task was to deliver a solution that could be implemented in today’s production of the FH truck. To make the project successful it was most important that the end result had a high maturity level. For that reason an analysis of ergonomic, laws and regulations, and possible materials where conducted. To show that this project is profitable and can be realized a ruff cost estimated of material and tools is added to the research. By doing smart material choices and not changing more than necessary existing part or for that matter add more parts the outcome is more economic then if the whole ingress module is change. Catia V.5 is used as a construction program and the built-in FEA module (Finite Element Analysis) to check the strength of the construction. This is done to see that the product withstands the applied force from a person. The project result is a updated version on the ingress module where the footboard is easily change without having to remove any parts of the module. What has happened is that the footstep is divided in to two parts, one frame that’s mounted on the chassi on the truck and one footboard that is mounted on the frame. That meant that the plastic cover hade to be change as well as the footsteps. The assembly line for this new ingress module is almost identical to what it is today besides the footboard that’s added. The weight has been reduced with 15 % without doing any bigger changes on the assembly line or adding cost (if not counting for new tools).
