Description / Abstract:
Preface
Development of this book began in 1997, after the 1997 Sunrayce
event. I had then been involved in designing and building three
solar cars that participated in the 1993, 1995, and 1997 Sunrayce
events, respectively. As the coach and advisor for a university
solar car team, I had the problem of losing some key students with
each project. The new students joining the team had the same design
misconceptions that the veteran students had when they began and
would want to make the same design mistakes that had been made on
previous cars. Making the same design mistakes again provides a
good educational experience for the students but does not further
knowledge of solar car design. To make progress and continually
improve our design efforts, I developed a course on solar car
design and wrote notes to support the course. The purpose of the
course was to get the new students up to speed, and the course
focused on what is important in designing a competitive solar car.
The notes became a little more formal each time I offered the
course, and evolved into this book on solar car design.
The material in this book is based on my experiences designing
and building five solar cars over the last twelve years. I have
tried to keep the book general and offer design options so that it
is not just about how the University of Missouri-Rolla team designs
solar cars, but there is a certain amount of bias in our design
philosophy. The book was designed to be used in a course that is
open to upper-level students majoring in any field of engineering,
mathematics, or science. Solar car design is an interdisciplinary
topic, and the book was written to be suitable for the junior,
senior, and graduate students who would be responsible for
designing the car. Students entering the course are assumed to have
a fundamental understanding of calculus, differential equations,
physics, and chemistry. The book provides an introduction to all
aspects of designing, manufacturing, and racing solar cars but does
not provide all of the details on any topic. Design groups will
have to go deeper than what is provided in this book to design any
of the systems on the car. Everyone on the team needs to have a
fundamental understanding of what is involved in designing,
building, and racing the car. Understanding the "big picture" will
help team members make design and manufacturing trade-offs to stay
on schedule and allow time to test and practice racing the car.
Testing and practice are an important part of being successful in
the competition.
To do well in a solar car race, the team must have a good car,
good drivers, good weather information, good strategy, and a
well-trained support team. Doing a poor job on any of these
elements will hurt the performance of the team in the race. The
main focus of this book is on designing the car because that is the
most difficult and time-consuming part of the project, but the team
needs to recognize that the car is not the whole project. Driver
training, accurate weather forecasting, race strategy, and practice
in driving the race route make a huge difference in how well the
team performs in the competition.
The first two chapters in the book are on energy management, and
the information in these chapters is helpful when doing design
trade-offs and developing a strategy for racing the car. Chapter 2
includes information on how to drive the car efficiently and is
helpful in driver training. Chapter 3 focuses on design methodology
and project management and provides an introduction to the general
design process. The remaining chapters are about designing the
different subsystems of the car. In each chapter, I have referred
the reader to books and articles that I have found helpful on
designing and building solar cars. The goal of the book is to
provide an introduction to all aspects of designing, building, and
racing solar cars.
