Reuleaux Kinematic Mechanisms Collection

原始链接: https://digital.library.cornell.edu/collections/kmoddl

The Kinematics Models for Design Digital Library (KMODDL), created at Cornell University (2003-2005), is an open-access, multimedia resource for studying kinematics and machine history. It's centered around the Reuleaux Collection of Mechanisms and Machines, a significant collection of 19th-century machine elements used by Franz Reuleaux, the founder of kinematics. The collection, housed at Cornell, features over 200 models he used for teaching mechanical motion. The KMODDL provides online access to the Reuleaux Collection through images and descriptions within Cornell University Library's Digital Portal. Supporting books and documents are located in the eCommons repository. The original KMODDL website, initially part of the National Science Digital Library, is archived via the WayBack Machine. The Reuleaux models are categorized using the Gustav Voigt manufacturer's alphanumeric system, reflecting a simplified version of Reuleaux's machine element taxonomy. This system uses letters to denote mechanism classes and numbers for specific instances within each class.

A Hacker News thread discusses Cornell's Reuleaux Kinematic Mechanisms Collection. One commenter, Animats, laments the loss of other historical collections, citing examples like the U.S. Patent Office models and the Smithsonian's clock escapement exhibit. Another user, cbames89, fondly recalls the collection from their undergraduate days, finding inspiration in the mechanisms. PaulHoule mentions past work on KMODDL at Cornell, highlighting the intriguing gear designs on display in Duffield and Upson Hall. The conversation reflects an appreciation for these physical demonstrations of mechanical principles and a concern for the preservation of similar historical artifacts.

The Kinematics Models for Design Digital Library (KMODDL) was developed at Cornell University in 2003-2005 as an open access, multimedia resource for learning and teaching about kinematics – the geometry of pure motion – and the history and theory of machines. The core of KMODDL is the Reuleaux Collection of Mechanisms and Machines, an important collection of 19th-century machine elements held by Cornell University’s Sibley School of Mechanical and Aerospace Engineering. The Reuleaux Collection at Cornell University comprises more than 200 models developed by Franz Reuleaux (1829-1905), the founder of kinematics, for teaching and researching the principles of mechanical motion. The KMODDL Collection in the Cornell University Library Digital Portal provides online access to the Reuleaux Collection via still and moving images and descriptions of the models. Books and full-text documents related to KMODDL are located in the eCommons repository.

The original KMODDL digital resource was a collection in the National Science Digital Library, developed through a collaborative grant with the faculty of the Cornell University College of Engineering, the Cornell University Library, and several external partners. The original site has been archived and is made available via the WayBack Machine Archive-It service. (NOTE: not all resources or navigation are functional on this archived version of the KMODDL website.)

Further background on Kinematics, the Reuleaux Collection and the KMODDL project can be found under About KMODDL based on information written for the original site.

The Reuleaux models are classified according to the alphanumeric system employed in the catalog of the manufacturer, Gustav Voigt. The letter in a model's ID (e.g., D14 or S35) refers to a class of mechanism; the number is a specific instance of the class. This classification scheme is a simplified version of the taxonomy of machine elements elaborated in Reuleaux's work.
