Framtagning av kalibreringsverktyg för referensmätningar : Vardaglig kontroll av kalibrering i industriell provbänk för pneumatiskt styrda tågbromsar

Sammanfattning: Faiveley Transport Nordic AB is a company in Landskrona and which is an international supplier in the railway industry. The industry sight in landskrona is mostly focused on developing and manufacturing train brakes.Today, Faiveley has a number of test benches that needs regular checks and re-calibration every three months. In the current situation, it is the responsibility of the lab engineer to check that the calibration is correct on the test benches and adjust if needed. The purpose of this research is to design a reference object that will be used for checking the calibration on a test bench.During the research, the product development process was used with some tools from the design thinking process. The research begins with a lot of theoretical background about BFC (Brake Friction Concept), test benches and calibration to develop a deeper understanding for the different concepts.Since Faiveley had already identified the problem, the method was started directly by looking for other solutions that could inspire the solution to the problem. The search for inspiration was conducted through various methods such as patent searching, trend watching and techwatching. The authors proceeded by choosing the best possible ideas for them to create a prototype of the best concepts.After creating a prototype of the reference object, the objects function was verified by testing on a test bench to check if it meets the preset requirements. The authors were able to get the result for each one of them three measurement parameters such as force, distance and pressure. Results showed that most of the requirements was accomplished.Based on the results several conclusions could be drawn. Such as that the reference object that was the solution to the problem worked and partly fulfills the associated requirements. Through this research a method has been created for how to generate reference values for similar parameters in general contexts, which others interested can use in the future.
