Wear rig for linkage in forestry machine tracks (English)
Abstract [en]

This project has been executed at the forestry machine track manufacturer Olofsfors AB and has been aimed at development of a rig for simulation of the wear that occurs in the linkage of Olofsfors AB forestry machine tracks. The problem is that link hooks in the tracks wears out first, often several times faster than other components. Olofsfors AB want to be able to test this wear in a controlled environment. The purpose of the wear rig is to distinguish what type of wear that is in effect as well as be able to optimize materials for Olofsfors AB: s products.

 

The project began with an pilot study of different types of relevant wear and different types of complete methods of wear measurement and simulation to better understand the problem. After this a market screening of existing machines and rigs that could be of interest was done. The project continued with creation of concepts of wear rigs and methods of wear. After a selection process the project proceeded with one concept to a 3D prototype.

 

From the market screening it could be found that the market is very thin with few suppliers. Their products are relatively expensive and need specially made test samples. The recommendation to Olofsfors AB will therefore be to construct a rig themselves. The market screening could be used by Olofsfors AB as a basis if they decide to expand their test activity in the future. 

 

The project reached the overall goals and delivered a prototype that passes the set demands. This means that the project is basically ready to move on to construction of a physical wear rig. There are still some problems to overcome but these will be easiest to solve during the construction phase. 

Abstract [sv]

Projektet har utförts hos skogmaskinbandstillverkaren Olofsfors AB och har gått ut på att ta fram en rigg för att simulera den nötning som uppstår i länksystemet på Olofsfors AB:s skogsmaskinband. Problemet är att länkkrokar i banden nöts ut först, ofta flera gånger snabbare än andra komponenter. Nu vill Olofsfors AB kunna testa denna nötning i kontrollerade miljöer. Syftet med nötningsriggen är att kunna avgöra vilken typ av nötning som verkar samt kunna göra materialoptimering för Olofsfors AB:s produkter.

 

Projektet inleddes med en förstudie av olika typer av relevant nötning samt olika typer av färdiga metoder för att mäta och simulera nötning för att förstå problemet bättre. Efter detta gjordes en marknadsundersökning av befintliga maskiner och riggar som kan vara av intresse. Projektet fortsatte med konceptgenerering av nötningsriggar och nötningsmetoder. Efter utsållning gick projektet vidare med ett koncept till en 3D-prototyp.

 

Från marknadsundersökningen konstaterades det att marknaden är väldigt smal med få leverantörer. Deras produkter är relativt dyra och kräver speciella provbitar. Rekommendationen till Olofsfors AB blir därför att konstruera en egen rigg. Marknadsundersökningen kan användas som underlag av Olofsfors AB om de vill expandera sin testverksamhet i framtiden.

 

Projektet nådde de övergripande målen och levererade en prototyp som klarar av uppsatta krav. Detta innebär att projektet är i stort sett redo att gå vidare till konstruktion av en fysisk nötningsrigg. Vissa problem kvarstår, men dessa löses enklast under konstruktionsfasen.
