Topological analysis of configuration evolution of a novel type of electric loader with metamorphic functions

Abstract

Traditional loaders are mostly hydraulic type, of which there exists some problems like high costs of manufacturing, assembling and maintaining. A novel type of electric loader with the ability to change its topological structures to satisfy various kinds of needs in the working process is proposed. One driving motor can finish multiple tasks such as shoveling, loading, lifting, and unloading. This paper introduces the source-metamorphic mechanism of the newly invented loading mechanism, as well as its metamorphic ways to achieve variable topology. The adjacency matrix and topological graphs are used to describe topological change of each working phase, based on which the principles and characteristics of configuration changing are analyzed. © Springer-Verlag 2012.
