Key Techniques

To meet energy-saving and environment-protective purpose, a series of plastic pumps are developed by composite molding. There are four key techniques involved, firstly, plastic hydraulic components with light-weight; secondly, steel barrel as a pump casing and a connection component as well; thirdly, floating impeller strategy where impeller is drifting freely along shaft; and lastly, a self balancing impeller technique which can totally keep axial force balancing. The manufacturing process is energy-saving, and the components can be recycled, which have great potentials for conservation of environment.

In order to maximize knowledge sharing and reuse in networked manufacturing process and improve the rapidity and reliability of decision-making, a knowledge-integration model and its implementation methods are proposed in this paper. First, the requirement for knowledge integration in networked manufacturing is analyzed. On this basis, a knowledge-integration model is built, and then three key technologies are studied, namely knowledge representation and organization based on ontology, knowledge correlation analysis based on complex network and knowledge supply based on decision-making context. This model provides an effective way to realize the optimum distribution of knowledge in networked manufacturing process and to improve the efficiency of decision-making process.

Abstract In order to effectively promote the construction of the Yangtze River economic belt, it has become China’s national strategy to vigorously develop the river-sea-going transportation. In the present paper, theoretical analysis, numerical simulation and model test are combined together to develop flat-type river-sea-going ship which is characterized with larger loading capacity, lower fuel consumption, better performance on energy-saving and environmental-friendly, excellent economy and higher transportation efficiency. Key technologies on hydrodynamic performance, structural safety, energy-saving technology and green ship technology are investigated to develop the river-sea-going ship. The developed “4E” level ship has great significance to the implementation of national strategic deployment.

The estimation approach of the work performed by the main force factors acting on the drill string, rotary and combined drilling methods, was proposed. The problem of obtaining analytical functions of force factors action for a mechanical system with distributed parameters was formulated. To solve the problem, the axial load and torque functions of the drill string analysis was performed, depending on the alternating parameter - the well depth. By integrating these functions, analytical dependencies were established for determining the axial load and torque acting on the drill string in sections of directional and S-shaped wells. Relying on industrial data, numerical calculations of the size of work on sections of such wells were carried out. The obtained research results can be further used to find energy-saving modes of the drill string.

The article contains the results of studies concerning the effects of selected parameters of the manufacturing process of elastic bellows on their elastic properties and strength. Bellows models were made using additive technology SLS selective laser sintering, in which the material used to construct models was a polyamide PA 2200. Bellows printing process proceeded in a surface parallel to the axis of the bellows and in a surface perpendicular to it. Based on measurements of deformation coefficients of elasticity of bellows were determined, also the measure of the maximum axial force exerted by the bellows while loading the internal pressure was carried out. Comparing the measurement results a significant effect of process parameters on the flexible properties of elastic bellows and their resistance to internal pressure were determined.

For enhancing energy-saving for construction engineering project, energy-saving oriented matrix management mode (ESOMMM) is proposed. The frame of the ESOMMM in engineering project is established from two dimensions (basic stage and key content). Under the precondition that the key contents are implemented, the key energy-saving techniques are respectively studied from planning, building, rebuilding and usage stage. And the coordination optimization model for key techniques under ESOMMM is established to solve conflict among varied key techniques. The energy-saving achievement after application is analyzed by applying ESOMMM, its key techniques, and the coordination optimization model in Shenyang city. The result shows that above mode, key techniques and model in engineering project will be benefit for enhancing the energy-saving greatly.

Case Base

Experience accumulation and reuse are very important for manufacturing of complex product. However, there is no mechanism to support such function in the integrated manufacturing system based on semantic SOA which is generally accepted as an effective approach to raise productivity. Specific to this problem, we propose a solution by building a case-base in semantic SOA to improve the traditional framework, in which case-base can accumulates the experiences by case study and reuse them by case retrieve. In this paper, the new architecture and workflow of the semantic SOA with build-in case-base is designed, merging and maximizing the advantages of both case-base and SOA to make up the lack of experience accumulation and reuse mechanism. Then, combined with field characteristics of complex products’ manufacturing process, construction and implementation concerning key technologies and methods of case-base are comprehensively elaborated.
