Design and development of a modular test system for testing of railway coupler components and subsystems

Sammanfattning: Dellner couplers AB is a developer and producer of railway coupling systems. This project is a master thesis that focuses on improving the quality, quantity and efficiency of their test department. This project details the design and development of a multi functional test rig that would serve as a basis for expansion decisions of the test department at Dellner. The resulting design was developed using the product development process by Ulrich and Eppinger with different phases. The phases being project planning, concept development, system-level design, detail design, testing and refinement and production ramp-up. However, some phases as described by the method would be altered or skipped for this project because of the limitations of the project and the nature of the product. The resulting design is able to perform four different tests that Dellner utilises today. This shows the potential of replacing four large test rigs with one of the new design. The design also has many different configuration options that enables an expansion of different types of tests. Simulations and calculations were made in order to verify the strength and functionality of the design.
