30 credits – Evaluation of parametric CAD models from a manufacturing perspective to aid...

Scania genomgår nu en transformation från att vara en leverantör av lastbilar, bussar och motorer till en leverantör av kompletta och hållbara transportlösningar.

Thesis project at Scania is an excellent way of making contacts for your future working life. Many of our current employees started their career with a thesis project.

Background:
The process to develop new concepts performance is often slow and often times difficult to document. Historically new concepts are evaluated through prototypes which results in an unnecessarily expensive and reactive process. Simulation driven design has through its many advantages solved a lot of these issues and has taken concept evaluation to a new level where parametric cad models has become a natural step in the process. This type of models allow a fast, broad and automated evaluation of the design space in order to find the best possible solution to a given problem.

Previous work in the area has focused on evaluating the design from a FEM, CFD and acoustic but in order to have a complete picture of the design cost and manufacturability are equally important aspects.

There are many ways to evaluate a components material thinning, draft, pressability, weight and manufacturing cost. In order to streamline the process these tools need to be connected to parametric models and used in conjunction with the previously mentioned simulation disciplines.

Target:
The target of this thesis is to develop a method for how to automatically evaluate the cost and manufacturability of a parametric model. The method should be usable in a simulation driven design process with fast iterations and it should be possible to evaluate the model alongside FEM, CFD and acoustics.

Assignment:
The scope of this thesis is to investigate how to automate the process of manufacturability and cost estimation and will focus mainly on:
  • Investigate what possibilities there is to evaluate sheet metal manufacturability and cost with available methods and software at Scania but also investigate new opportunities.
  • Identify functions and parameters that are important in a parametric model in order to evaluate cost and manufacturability.
  • Connect parametric models with relevant tools in order to create an automated and easily comprehendible evaluation of silencer designs.
  • Present and document methodology.
Education:
  • Masters student in mechanical engineering or similar.
  • Experience with design automation and parametric modelling in Catia V5.
Number of students: 1-2
Start date: January 2019
Estimated time needed: 20 weeks
