Nonlinear Optimization of Vehicle Safety Structures provides a cutting edge
overview of the latest optimization methods for vehicle structural design. Focusing on
large deformation structural optimization algorithms and applications, this book covers
the basic principles of modern day topology optimization and compares the benefits
and flaws of different algorithms in use. The complications of nonlinear optimization
are highlighted, along with the shortcomings of recently proposed algorithms.
Using industry relevant case studies, the book demonstrates how optimization software
can be used to address challenging vehicle safety structure problems and explores
the limitations of the approaches given. The book will also discuss the requirements
for a large deformation (nonlinear) optimization algorithm, and comparisons of the
results in relation to currently available (commercial) FE based optimization software.
Intended for crash engineers, restraints system engineers and vehicle dynamics
engineers, as well as other mechanical, automotive and aerospace engineers,
researchers and students, Nonlinear Optimization of Vehicle Safety Structures
is an essential structural optimization resource that puts the latest research findings
to work for practical results.
Key Features
Focuses on nonlinear, large deformation structural optimization problems
relating to vehicle safety
Discusses the limitations of different algorithms in use and offers guidance
on best practice approaches through the use of relevant case studies
Draws on research work with the likes of MIRA, Jaguar Land Rover and
Tata Motors European Technology Centre as part of multi-million pound
European funded research projects, emphasizing the industry applications
of recent advances
