Abstract: Different with the traditional expert classification of building ontology, Web-platform folksonomy is used to analyze the tagging of mechanical components in the networked and collaborative environment. And according to the combination of tags of mechanical components and ontology technology, the ontology model is given based on one instance by protégé to reveal the information characteristics of mechanical components more realistically and more completely. With the trend of realization of manufacturing informationization, the mechanical components ontology provides a contribution to the communication, sharing and knowledge reusing of mechanical products.

Abstract: Constraint-based model reconstruction is one of the key research problems in recent reverse engineering. Surfaces of structural parts are mostly quadratic and have mutual constraints. Aiming at this feature, the paper proposes a method for conducting constraint-based synchronous fitting on multiple surfaces. Synchronous fitting is carried out through constraint optimization method, the constraints among surfaces can be maintained and the original design intents incarnated.

Abstract: In this paper, a new type of hydraulic test bed is developed which can be used for performance testing of hydraulic valves, hydraulic motor and hydraulic pump. The composition structure diagram of hydraulic system, power supply system, and the signal flow diagram of data acquisition system were designed. The characteristics of the LabWindows/CVI development tools and the usage of Prodave MPI/IE 6 network communication tools were introduced, also the database storage and access technology in LabWindows/CVI environment. It was proved through the practical application that the test bed is reliable and has the merit of higher precision and automation level, and simple operation.

Abstract: Based on the preprocessed measuring data, this paper proposes a method for identification and reconstruction of regular curves and surfaces including straight line(segment), circle(arc), four-sided plane and right cylindrical surface. Considering the geometric feature of each kind of regular curve or surface, the paper studies the corresponding algorithm for identifying the curve or surface point set, reconstructs the curve or surface and gives the parameter equation.

Abstract: In large inclined angle mining condition, in order to decrease the effect of sliding force, a lightweight design for hydraulic support is presented in this paper. Taking minimum mass of top beam as optimization objective, the three-dimensional model of it is built firstly. The whole top beam is simplified into top plate, side plate, bottom plate and main reinforcement on the premise of unchanging its topology configuration, and only strength constraint is chosen as constraint, which reduces the number of constraint functions and calculation cycles. By means of ANSYS zero-order optimization module, the mass of top beam is decreased about 16.9%. Finally, the optimal lightweight structure is fully evaluated under the same load as pre-optimization, and finite element analysis results prove that its stress and strain satisfy the need of strength. This lightweight design measure is used in the practical manufacturing with a lower cost of materials, which also increases the stability of hydraulic support in large inclined angle mining condition.

Abstract: This paper studied the fine registration techniques of measuring data of complex product and proposed a new registration method based on triangle constraint. Firstly, the paper made a research on specifying the proper measuring reference points and the setting of reference coordinate system, and afterwards proposed a fine registration algorithm of measuring data, Which is about realizing the fusion of reference coordinate system based on the congruent judgment of reference triangle and fulfilling precise match of data with measuring error on the basis of controlling the rotation of data blocks and minimizing the registration error.

Abstract: Shearer cutting unit is the main working mechanism of the shearer and its performance is a direct reflection of the performance of the shearer. Three-dimensional solid model of shearer cutting unit mechanical system was built by 3D modeling software Pro/E, and then it was imported into ADAMS through a dedicated interface module. After adding constraints and movement driven and calibrating model, the simulation analysis in the ADAMS was established and analysis of the forces of the three key pin hinge point was achieved, which provided the basis for the shearer cutting unit mechanical system design.
