Thesis work - Minimal statistical equivalent for Virtual Public Roads

About this opportunity – Background

Vehicle durability is all about safety! Safe for use over the vehicle’s lifetime. Loads acting on the vehicle will be one of the key parameters to describe vehicle life and its long term performance. Loads can origin from what Car your drive, in what Environment you utilize your vehicle and how your Use your vehicle. Needless to say, roads are a key part of the environment traversed and being able to describe them is key for engineering.

In an ideal world all the road surfaces traversed by customer vehicles would be scanned and stored in a database. However, it would not be practical to re-simulate all the roads in the world. Thus, statistical equivalent roads, of a specific road, of a complete road network or of a specific road network used by a customer profile would be one possible approach to assess customer behaviour.

Objective
The master thesis is intended to investigate and evaluate roads and statistical road models. The end goal would be to suggest a minimal set of parameters to capture from actual roads to successfully create a statistical equivalent representation with durability metrics in focus. Also, using the minimal set of parameters, what re-creation method is suggested? Thus, focus will be on re-creating vertical loads acting on the vehicles originating from the road surface.

Scope of the thesis work

The students will work with real world 3D scanned road surfaces of varying content.
1.    Literature review on statistical road models both in terms of descriptive metrics (for example: Coherence, Waviness, Roughness and Transient Extraction) as well as modelling and re-creation (for example: General Roughness, Transients, 3D Surface).
2.    Data screening for relevant metrics from scanned roads including evaluation of dataset size need for a statistical base large enough for relevant re-creation.
3.    Multibody simulation using actual 3D scans as well as simulation of proposed 2D and/or 3D statistical representations. I.e. a simulation to simulation comparison.
4.    Correlation and evaluation of metrics and methods used for statistical representation
6.    Write and present thesis report. 

What you'll bring

Data extraction and analysis will require knowledge in statistics and data processing. Simulation of the scanned roads as well as re-created statistical equivalents will require knowledge in multibody dynamics. This work is preferably performed by two students in collaboration.
