Topological Analysis of Configuration Evolution of a Novel Type of Electric Loader with Metamorphic Functions

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.

Design of the Human–Machine Interface of the Control System of a Novel Controllable Mechanism Type Mechanical Excavator

This paper introduces the design of the Human–Machine interface of the control system of a controllable mechanism type planar 3 Degree-of-Freedom mechanical excavator. Based on the kinematics model and the control principle block diagram of the excavator, the interface is established in the C++ programming language, which consists of five parts: (i) speed setting module, (ii) position setting module, (iii) driving information module, (iv) the start button and (v) the stop button. The program codes of each module are given specifically.

Biological Modeling Representations and Configuration Evolution Analysis of a Novel Metamorphic Loading Mechanism

A novel electric loading mechanism is introduced in this paper by applying metamorphic mechanisms to the innovative design of loaders, which can change its topological structure to satisfy various kinds of demands during the working process. One driving motor can finish multiple tasks such as shoveling, rolling, lifting, and unloading. This paper introduces the characteristics during the evolutionary process first, based on which, two 0-DOF (Degree-of-Freedom) directional Assur groups are developed to be the new metamorphic cells as well as their representations. Configuration transformation and its degeneration ways during the genetic growth are studied. Biological modeling for working-phase mechanisms is proposed. The evolutionary synthesis process for generating the source-metamorphic loading mechanism and its representation is introduced through evolutionary operations.
