Abstract [en]

Since 1949, Ålö AB have been developing and manufacturing front loaders for agricultural machinery under the brands Quicke and Trima. These front loaders are delivered in some configurations with a mechanical joystick mounted inside the tractor cab. For ergonomic reasons, it is often chosen to mount it in a recessed hole located in the tractor cab's interior panel. When this is done today, the hole is covered with one and the same rubber gaiter in all machines. Over the years, it has been noted that there is a certain quality difference in the assembly between the different models of agricultural machinery. The development department at Ålö AB now wants to review the possibilities for a more model-adapted coverage of the holes. Where no modification have to be made in either the interior panel or the new solution. The objective of this work is to develop three concepts and associated manufacturing methods for more model-adapted solutions. These will then be evaluated against the requirement specification that deals with assembly, construction time, lead time and assembly requirements. Since it is small varying series between 20 and 100 parts per year, the focus of the work has been on evaluating different manufacturing methods as the serie sizes affects lead times and prices. For the different concepts, a cost and lead time comparison has been made. From this, it can be seen that all manufacturing methods are useful in different series sizes. But the additive production stands out as it has both shorter lead times and lower retail costs than other manufacturing methods in all cases. This project can be viewed as a preliminary investigation, as no physical tests or prototypes have been made. The work lasted for ten weeks.
