86468 - Vehicle Virtual Design

Academic Year 2019/2020

Learning outcomes

Know and understand the fundamentals of the Virtual prototyping through the systematic approach to a complete DMU (Digital Mockup) that from the design concept leads to the engineering of a vehicle (car or motorcycle). Work independently and original, and apply multidisciplinary knowledge to the virtual design and optimization of systems and components in vehicle engineering. The student will need to learn the most advanced techniques of interaction between real and virtual prototype through the principles of human-machine interaction. Developing the ability to work within a workgroup, planning and managing the activities needed to achieve technically valid project results.

Course contents

The course deals with virtual prototyping and offline and interactive simulation methodologies that allow to continuously support the development of the product in the automotive field in the conceptual and pre-production phase.

In particular the course topics are:

1) Virtual Engineering vs. Physical Engineering
a) virtualization in the design process
b) SBD-Simulation based Design
c) Combined multiphysics simulations: FSI, etc.
d) the concept of Man-in-the-loop

2) Main techniques to support the concept phase
a) references to sketch-based modeling and modeling
interactive
b) organic and mesh-based modeling techniques
c) Reverse Engineering methodologies and systems
d) Reverse Modeling for rapid virtualization of
geometry

3) Perceptual problems in the physical and visual field
a) the concept of real and virtual perception
b) the foundations of ergonomics
c) cognitive ergonomics

4) Product development methodologies using environments
interactive graphs
a) fundamentals of digital interactive graphics
b) pipeline rendering
c) hardware for 3D graphics
d) the main light simulation models
e) static rendering and digital animation
f) realtime rendering in concept development
g) Realistic and hyper-realistic visualization principles for the
product presentation and design review

5) Virtual prototyping techniques
a) the Milgram continuum
b) Virtual Reality
c) Augmented Reality
d) Mixed Reality of the real and virtual prototype
e) Design Review in VR and AR

6) Physical prototyping
a) TCT techniques (Time Compression Techniques) e
rapid prototyping
b) Milling manufacturing and Additive Manufacturing for
the implementation of the real prototype and its own
incremental changes
c) development of assembly sequence simulation
d) disassembly simulation in virtual simulation systems

7) Maintenance and virtual training
a) Interactive 2D and 3D manuals
b) Augmented Reality systems for staff training
c) interactive maintenance in Augmented Reality

Assessment methods

The learning assessment consists of an oral interview (single, not group).
All the simulations and / or exercises developed must be completed and discussed during the interview. Two questions will also be asked about the theoretical issues developed during the course.
The vote, expressed in thirtieths, will be awarded in total: exhibition of the exercises and oral examination.
