This volume is a basic introduction to information one needs to evaluate the strength of a trailer's framework. Structure generally covers a wide array of information, which we have attempted to condense for the purpose of this book. This book is a beginning guide to more in-depth analysis, should you need to explore further for you special purpose.
When we first started designing and building trailers, we were surprised to find very little information available to help us. To this day, little has changed. We were extremely disappointed then and can still empathize with you. The fact of the matter is that this industry has had very little development of any sophistication. Manufacturers doing development for their own products have kept information to themselves, for obvious reasons. And few have taken much time to test or expand the base of knowledge regarding trailers. Part of the reason for this is that, although a large quantity of trailers are built on a yearly basis, trailers are purpose-built and the quantity of each particular kind of trailer built does not justify research to any great extent. You can almost be assured that everything you need to design your trailer is not here. Hopefully, the book will at least sensitize you to some of the problems to be evaluated and your search for help can be more focused.
M.M. Smith is a mechanical-structural engineer whose unique trailer designs have become an industry standard, copied by many. A background which includes a design engineering position on Indy and sports type race cars and project manager/engineer on a Land Speed Record car, influenced Smith's high strength, light weight approach. Other engineering design work has included highway construction, heavy equipment, transmission and machinery.
Smith spent 17 years as CEO and chief engineer of IRD Trailers developing trailers to suit the discriminating demands of specialty vehicle owners. IRD Trailers became known not only for their lightweight, high strength designs and sleek appearance but also for their sway-resistant towing. Smith has been granted 14 patents relating to trailers improving their structure and usability.
Besides designing trailers and publishing how-to books, Smith also consults with major automotive companies and performs accident analysis on automotive and trailer related accidents. Smith's long time secret desire is to find creative and artful ways to build things out of metal, saving the trees for their work in providing shade and cleaning up the environment.
