Kinematic analysis of complex gear mechanisms [PDF]

open access: yes, 2010
This paper presents a general kinematic analysis method for complex gear mechanisms. This approach involves the null-space of the adjacency matrix associated with the graph of the mechanism weighted by complex coecients.

On Crossley's contribution to the development of graph based algorithms for the analysis of mechanisms and gear trains [PDF]

open access: yes, 2015
This paper celebrates a particular branch of Crossley's early work dedicated to Mechanism Science, which deals with a rigorous introduction of Graph Theory to the study of some fundamental and intrinsic properties of kinematic chains and mechanisms ...

Helicopter transmission arrangements with split-torque gear trains [PDF]

open access: yes, 1983
As an alternative to component development, the case for improved drive-train configuration is argued. In particular, the use of torque-splitting gear trains is proposed as a practicable means of improving the effectiveness of helicopter main ...
