Reconstruction Designs of Lost Ancient Chinese Machinery

Ancient China was outstanding in mechanical technology before the 15th century. Numerous ingenious machines were invented. However, due to incomplete documentation and loss of finished objects, most of the original machines cannot be verified and many of the inventions did not pass down to later generations. This book, based on the author's research and teaching experiences over the last 20 years, is devoted to presenting an innovative methodology in the area of mechanical historiography for the systematic reconstruction design of ancient Chinese machines that have been lost to time. Its purpose is to generate all possible design concepts of lost machines. If the defined and/or concluded design specifications, topological characteristics, and - sign requirements and constraints are feasible, one of the resulting rec- struction designs should be the original design. Such an approach provides a logical tool for historians in ancient mechanical engineering and techn- ogy to further identify the possible original designs according to proven historical archives. However, this work will not deal with the credibility of historical literary works. It supposes that the lost machines existed, and tries to demonstrate the feasibility of reconstructing the lost designs. The book is organized in such a way that it can be used for teaching, research or self-study. Chapter 1 introduces the study, classifications, and process for the reconstruction design of ancient machinery.

The first book of its kind, with a totally unique approach to both ancient and future machinery
