Stability Analysis of Composite Circular Lattice Structure
DOI: 10.16080/j.issn1671-833x.2011.19.001
In order to attain composite lattice structures with high load-carrying efficiency , stability of composite circular lattice structures are analyzed by using FEM. Parametric design program is compiled with the APDL language of ANSYS. Changing law of load-to-mass ratio which is attached to thickness of inner skin, thickness of outer skin , winding angle of inner skin and winding angle of outer skin is researched by utilizing the design program . As a result, when winding angles of inner skin and outer skin are equal to 90 degree, load-to-mass ratio of circular lattice structures is the lowest. In addition, when winding angles of inner skin and outer skin are the equal value, effi ciency of lattice structures is not too higher. When winding angle of inner skin and outer skin are not the equal value , and are appropriately selected, load-to-mass ratio of lattice structures can be more higher.

Experimental Study on Electrochemical Deburring of Miniature Hole
DOI: 10.16080/j.issn1671-833x.2011.19.002
The electrochemical deburring (ECD) is adopted to remove burrs which exist in the intersections of the miniature drilling holes and the inner wall of stainless steel pipe. By processing experiments, the influences of the machining parameters on the deburring quality and the change law of the voltage between the electrode and workpiece are explored, such as process time, electrolytic composition and concentration, fl ow forms of electrolyte.The ECD results show that the burrs can be removed with good quality and effi ciency in the condition of optimal selecting parameters.

Analysis and Calculation on Machining Deformation of Parameterized Thin-Wall Workpiece Based on ANSYS
DOI: 10.16080/j.issn1671-833x.2011.19.016
With higher demanding to reduce the weight of aviation products, many components used in the aviation industry usually adopt thin-wall structures. But, because of its poor stiffness, thin-wall workpiece deforms easily in machining process. So fi nite element model of parameterized thin-wall workpiece in machining process is estabilished and the machining deformation of thin-wall workpiece is calculated by using FEM software ANSYS 10.0. Because ANSYS can’t provide a relatively friendly graphical interface, a secondary development of ANSYS is made based on C#, and a friendly interface is developed. The software developed could call ANSYS to calculate in background after the users enter the parameters, so the efficiency of analysis could increase in a large degree.

Material Parameter Modification for Age Forming Simulation Based on Response Surface Model
DOI: 10.16080/j.issn1671-833x.2011.19.017
A modifi ed solution of material parameters is obtained by solving simulation error response function for material parameters, which is established by response surface methods combined with uniform design, in order to improve finite element analysis precise for springback in creep age forming. The simulation results with the modifi ed solution are in accord with experimental results.

Research of XML-Based Data Exchange Between Reverse Reconstruction Model and CAD System
DOI: 10.16080/j.issn1671-833x.2011.19.006
In order to make the reverse recon
struction model be parameter-driven model after being imported into conventional CAD system, CSG/B-Rep hybrid mode is applied to represent the reverse reconstruction model, and a XML-based description of data exchange format is proposed, which contains all required parameter information of CAD model. After second development of CAD system, the XML files can be imported into CAD system, and accomplish the data exchange between reverse reconstruction models which are represented by CSG/B-Rep hybrid expression mode and conventional CAD system, which expands the reconstruction signifi cance of reconstruction model. Finally, the method is verifi ed by an example of data exchange between reverse reconstruction model and CATIA system.

Prediction of Permanent Indentation Depth of Laminate Subjected to Low-Velocity Impact
DOI: 10.16080/j.issn1671-833x.2011.19.018
A method is presented to calculate the depth of the permanent indentation of laminates after low-velocity impact. It is based on the Hertzian contact law, and uses the finite element simulation results of the low-velocity impact. Two typical materials, T700/5428 and T300/5428, are analyzed and a comparison of the contact force history and permanent indentation between the calculations and impact test results is given which shows the feasibility and effectiveness of this method in the case of small damage. The method can provide a reference to predict the performance of the composite.

ceramic has a higher density. Meanwhile there are no obvious cracks and porous. The interwoven columnar crystal structure appears on the surface of ceramic block, which could prevent intergranular fracture. And typical equiaxed grain structure which can greatly enhance the performance of ceramic is presented on the coating cross-sections. Because this structures have higher toughness and strength. Meanwhile, in order to lay the foundation for future research work, the interaction of laser with the ceramic material and the densifi cation process are discussed.

Approach of Parting Design of Turbine Blade Based on Feature Decomposition and Parting Template Library
DOI: 10.16080/j.issn1671-833x.2011.19.020
A new approach of parting design of turbine blade based on feature decomposition and parting template library is put forward. The exceeding obstacles of turbine blade with complicated outer structure is addressed. First, automated feature recognition and man-machine interaction feature recognition are adopted to extract decomposition features of cavity. The core block of turbine blade is extracted to simple features. Second, for each simple feature, the parting design approach is selected automatically from parting template library. This new approach enhances the design effi ciency of turbine blade mould and sets a foundation of automated design of precise casting mould of turbine blade.
