Detta examensarbete har utförts hos Parker Hannifin Manufacturing Sweden AB i Trollhättan. Rapporten redovisar arbetet för framställning och utvärdering av koncept för en monteringsstation. I monteringsstationen monterar företaget tre modeller av hydraulpumpar betecknade F1, F2 och F3. I monteringsstationen finns en skruvstation som möjliggör montering av pumparna. Skruvstationen är dåligt anpassad för montering av F3 och monteringspersonalen riskerar att drabbas av belastningsskador på grund av bristande ergonomi i form av manuella lyft. Syftet med examensarbetet var därför att förbättra ergonomin för de anställda samt att öka flexibiliteten i skruvstationen. Målet var att ta fram ett koncept på en monteringsstation anpassad för F1, F2 och F3 med förflyttning av pump till och från skruvstationen där manuella lyft ej överskrider sju kg. Genom att samla information om nuvarande monteringsstation sammanställdes en nulägesbeskrivning samt en lista med tolkade behov och krav. Listan omfattade behov och krav hos monteringspersonalen, för att åstadkomma en fungerande monteringsstation och från organisationen. Baserat på insamlad information och uppmärksammade förbättringsområden genererades lösningar som kombinerades till koncept. Genererade koncept inkluderade lösningar för minskad belastningsergonomisk risk och möjligheter att standardisera verktygen i skruvstationen. Koncepten sållades i en konceptsållningsmatris där koncepten utvärderades mot nuvarande monteringsstation. Kvarvarande koncept betygsattes sedan i en konceptvalsmatris där ett vinnande koncept utsågs. För att uppmärksamma och åtgärda eventuella problem som kan uppstå då konceptet realiseras, utvärderades konceptet ytterligare genom att modelleras och simuleras i ett datorprogram.  Resultatet av konceptutvecklingsprocessen och det koncept som rekommenderas till Parker benämns "H+". Koncept H+ består av en transportbana med en integrerad skruvstation samt en lyftanordning mellan transportbanan och nästa moment i monteringslinan. Skruvstationen har en roterande axel där F1, F2 och F3 fixeras med ett standardiserat verktyg. Den roterande axeln möjliggör momentdragning av skruvar framifrån. Montering av F3 har i konceptet anpassats genom standardiserade verktyg. Konceptet minskar även belastningsergonomiska risker då förflyttning från skruvstationen görs med transportbanor och lyftanordning. Manuella lyft över sju kg har därmed eliminerats. Väljer Parker att utveckla och realisera konceptet kommer de enligt genomfört arbete att erhålla en monteringsstation med ökad flexibilitet och förbättrad ergonomi för deras anställda. / This bachelor's thesis has been carried out at Parker Hannifin Manufacturing Sweden AB in Trollhättan. This report presents the work for producing and evaluating concepts for an assembly station. The company assembles three models of hydraulic pumps named F1, F2 and F3 in the assembly station. In the assembly station there is a screwing station that enables assembly of the pumps. The screwing station is badly adjusted for assembly of F3 and the assembly personnel may suffer from damage due to lack of ergonomics in the form of manual lifting. The purpose of this bachelor's thesis was therefore to improve ergonomics for the personnel and increase the flexibility in the screwing station. The goal was to produce a concept of an assembly station adapted for assembly of F1, F2 and F3 with transport of pumps to and from the screwing station where manual lifting does not exceed seven kilograms. By collecting information on the current assembly station, a zero-position description and a list of interpreted needs and requirements were complied. The list included the needs and requirements of the assembly personnel, to achieve a working assembly station and from the organization. Based on collected information and identified improvement areas, solutions were generated and combined into concepts. Generated concepts included solutions for reducing ergonomic risk and the possibility to standardize the tools in the screwing station. The concepts were screened in a screening matrix where the concepts were evaluated against the current assembly station. The remaining concepts were graded in a selection matrix where a winning concept was selected. To identify and resolve any problem that may arise when the concept is realized, the concept was further evaluated by modelling and simulating in a computer program.  The result of the concept development process and the concept recommended to Parker was named “H+”. Concept H+ consists of a conveyor with an integrated screwing station and a lifting device between the conveyor and the next part of the assembly line. The screwing station has a rotating shaft where F1, F2 and F3 are fixed with a standardized tool. The rotating shaft allows torqueing of screws from the front of the screwing station. Assembly of F3 has been adapted in the concept through standardized tools. The concept also reduces ergonomic risks, as transport from the screwing station is made by a conveyor and a lifting device. Manual lifting over seven kilograms has thus been eliminated. If Parker chooses to develop and realize the concept they will, according to this report, be provided with an assembly station with increased flexibility and improved ergonomics for their employees.

Bad worker health leads to an unnecessary increase of absent days and loss of money, particularly the more physically demanding jobs as in industry. This can be seen in both a broader perspective and also in the suffering of the individual. In order to stop this trend and lower the work injuries connected to bad ergonomics good, reliable, and preferably digital, methods have to be generated and evaluated. The aim of this master’s thesis is to investigate how Digital Human Modelling (DHM) tools can beused to evaluate physical ergonomics by building a real-life workstation in the DHM tool IPS IMMA. The workstation used here is based on a newly installed station at a large company placed in Skövde. This station was developed in collaboration of both technical specialists but also ergonomist consulting from the company Feelgood. The goal has therefore been to examine where in the process a DHM tool could be used and if it would contribute to the process. The methods chosen to investigate the use of DHM tools were to build a final model in IPS IMMA, which is based of four different versions of the workstation. By building four different versions of the workstation the process has simultaneously been analyzed and documented in order to compare the findings made in the program to the ones made in real life. The results have also been made in combination to finding the opportunities, challenges, and disadvantages with using DHM tools. The needed improvements within the DHM field have also been noted and discussed.
