Sammanfattning
This thesis describes the theoretical work that has been done during a reconstruction of a
towing mechanism. This work has been issued by a company named VM Trailer. VM Trailer
is a company that dedicates towards modified trailers for transport of heavy machinery. The
purpose of this work has been to construct a foldable towing mechanism with the aim of
attaching a coupling device. This coupling device is set to be centered, with a location of 400
mm horizontal and 460 mm vertical behind the trailer’s hollow bar. Further conditions have
been that the construction must endure the dimension load with a safety factor of three.
The process for development was launched with a conduction regarding the problem in of
itself. Here the problem was split into three phases. Based on these three phases together with
conditions for the project, a specification of requirements was established. With the help of
results from online searching and idea generating techniques with the requirements in mind,
several concepts were drawn. These concepts were then compared absolutely to the
requirements and later relatively towards each other with the help of established methods. At
this stage, two concepts were elected for further development. With the help of CATIA-V5,
CAD-models and FEM-models were made. These concepts were then evaluated through
these models in order to choose the final concept.
The result from this project was a visual model of the concept that was selected as the final
concept. The model was the same as the CAD-model made earlier. Drawings of all
components in this concept were made. Some of the requirements for the final concept could
not be verified, requiring further work and testing.
