All thesis projects are arranged in business critical areas and therefore you will be able to contribute to our company purpose – providing freedom to move in a safe, sustainable and personal way – from day one! 

 

 

Background
In the car body there are several single parts that build up to a body complete. To be able to meet the final quality requirements for the assembly, there are tolerances defined for each part. This set the requirements for the supplier to fulfill before delivery of parts to Volvo. The supplier needs to measure a defined number of parts in each batch. To quality assure the measurements the supplier also needs to perform an analysis of the measurement system (eg. fixture, measurement machine and handling of operator) to analyze how much of the measured variation is actual part variation and how much comes from the measurement system.

 

There are several structural body components that are long and slim which is a challenge. E.g A-pillar reinforcement upper is a long and slim part with a twisting shape that is hard to control for the operator due to its size. Lessons learned is that it is difficult to get a robust reference system that will give stable measurement result. Our suppliers generally want to add support points to force it into correct shape. Trials have been done with choosing reference points either on the weld flanges or on first form surfaces. Also, trials with standing (car coordinate) fixtures and lying down fixtures have been evaluated. The aim with this master thesis work is to compare the outcome from these trials to find a general guideline for how to perform an MSA for the coming projects.

 

Scope
In this work a detailed study of the measurement system analysis will be done

  • Literature study to understand and map MSA way of working, documentation, methods, performance and result
  • Literature study to understand and map fixture functionality, reference system definition and requirements
  • Evaluate setup in previous projects
  • Build virtual fixture simulation model in RD&T software to compare virtual result with measurement data
  • Perform MSA simplified study to verify new guideline

The goal is to establish a general guideline for how to perform an MSA for the A-pillar reinforcements in coming projects.
