Abstract [en]

During asphalt compaction it has been observed that many drivers are leaning out of the window to improve their vision of the drum edge. The improved vision is necessary to know how the drum edge is positioned in relation to the edge which is supposed to be followed. Using this posture during workdays is not ergonomic and may result in occupational injury in both the back and the neck.

  

The purpose of this thesis is to, together with Dynapac Compaction Equipment AB which is a part of the Atlas Copco group in Karlskrona, design and prototype a solution that can be used to improve the ergonomics for the asphalt roller drivers. The solution is not supposed to cover all areas, there will still be situations where the driver has to lean outside the window for instance when the compaction is done close to a wall. The main use of the solution is situations when the compaction is performed on an open road with free edges.

 

To achieve a solution to the problem described above a product development process similar to Ulrich & Eppinger’s process has been used. Ulrich & Eppinger’s process has been used as a basis while being slightly adapted to fit the thesis. The adaptation has resulted in a less linear process for the thesis. The used product development process consists of the following steps: research, concept development, concept selection, construction phase and prototyping. In the research step interviews have been performed with different asphalt companies in Sweden. From these interviews needs have been found which have been translated into requirements. The needs and requirements have been the basis for the concept development and concept selection where the most suitable concepts were chosen for continious work in the construction phase and the prototyping. 

 

The solutions of the described problem resulted in a camera which will be used to improve the drivers’ vision. The study showed that a suitable placement for the camera is the front right side of the cabin roof. This position gave a desired view with a good perspective in front of the roller combined with vision of the drum edge.  

 

Further work, which is not included in the thesis, would be to test the solution and prototype in a real work related environment. If this test results in positive feedback Dynapac will have a concept which will give an advantage on the market regarding improvement of driver ergonomics.

 

The authors consider the problem statement of the thesis to be fulfilled containing a solution which will contribute to a basis for further work in the future related to driver ergonomics.
