16 Bézier Segmentation of T-mesh in Parametric Space Based on Queue
CHEN Tiantian, CHEN Lu, WANG Wei, ZHAO Gang
DOI: 10.16080/j.issn1671-833x.2017.07.016
Aiming at the problem of Bézier segmentation of T-mesh in parametric space, an algorithm based on
queue was proposed. Firstly, T-mesh is segmented by the extension of T-vertices. Then a further segmentation is implmened
by every nonzero region of blending function which is coupled to a vertex in T-mesh. An array of queue is used
to realize the actual segmentation of the face in T-mesh. Some typical examples are illustrated to verify the validity of the
algorithm at length.

WU Rong, ZHANG Dan, WEI Tao, XU Feng, ZUO Dunwen
DOI: 10.16080/j.issn1671-833x.2017.07.056
As the only basis for the manufacturing process, MBD model has gradually become the development
trend of the aviation manufacturing industry, and it has been applied to the CAD/CAM system. However, MBD technology
has not been used in the CAPP, which results in the poor information flow of the MBD data set during the integration
of CAD/CAPP/CAM. In this paper, according to the requirements of NC machining of the aviation structure, the MBD NC
machining process model is built based on layers. The work flow of NC machining process based on MBD is proposed. The
CAPP system of NC machining based on MBD is researched and developed. The MBD application of integrated design and
manufacture on UG platform is realized finally.

Affect factors of spring-back for C-shaped composite spars generally include geometry, shear effect between
plies, and mold, et al. The factors often bring to process-induced distortion in composite structures which would lead
to bad geometric accuracy. Through analyzing the factors by theory approach, the FE calculation and experiment method,
the spring-back values of C-shaped spars in structures of aircraft are calculated and the weight values of the factors are also
estimated, which could be used to provide some bases for distortion prediction and control for C-shaped composite spars.

DOI: 10.16080/j.issn1671-833x.2017.07.078
Chatter easily occurs during the milling process of thin-walled part, and the stability limit is varied due
to the changing of part dynamics. The passive damping technology based on viscoelastic material is investigated in order
to promote the damping ratio and machining stability of the thin-walled part. A methodology consisting of damping layer,
restraint layer and mass layer is proposed. Modal tests show that it is effective in damping multiple modes. Finally, it is applied
to the five-axis milling of thin-walled S part. Experiments under multiple configurations of cutting parameters show
that the vibration amplitude is decreased by 97%.

test and mechanical test. The results show that the width of high frequency TIG weld is obviously narrower and the
grain size is decreased by more than 30%. It also shows that the alpha phase layer is thicker than that of the conventional
welding, and the distribution is more regular and more ordered. The tensile strength of the ultra high frequency pulse welding

ZHOU Lina1, LI Zhiqiang1,2,3, HAN Xiaoning1,2,3, ZHANG Xingzhen1
DOI: 10.16080/j.issn1671-833x.2017.07.092
A finite element model is established to simulate the hot bending process of titanium alloy sheet by using
ABAQUS software. The stress and strain distribution and the influence of process parameters on the forming process are
analyzed. The results indicate that deformation distribution mainly concentrates at the center position of the thickest area.
When the new contact position appears between the upper die and the sheet, the forming sheet enters the correction bending
phase and the forming force increases sharply. When holding 600s, the maximum springback displacement and the upper
die forming force reduces 84% and 94%, respectively. The simulated result shows a good agreement with the deformed part
at the same conditions.

DOI: 10.16080/j.issn1671-833x.2017.07.097
CNC Polishing can have a low roughness with a high consistency. The influence of CNC polishing of wool
felt wheel on residual stress is investigated. The normal residual stress in the feed direction shows a trend from rise to decline,
while in the vertical feel direction it stays unchanged basically and then decreases. The optimized times of polishing
is 3. The “Reinforcing Bar” model is put forward in order to explain the impact on the residual stress from polishing. Another
polishing experiment is conducted for verifying roughly the impact relation.

In the process of carbon fiber reinforced plastics (CFRP) drilling, layer is the most important class of defect,
which seriously affects the connection performance of the holes and the service life of materials. Rule especially antilayer
rule is used for optimization design of laminated composite plate structures. The stacking sequence of composite
laminate is optimized by applying Memetic algorithm, and drilling experiment of carbon fiber reinforced plastics is made to
check the validity. The result indicates that the stacking sequence has great influence on layer, and the optimized composite
laminate can effectively restrain layer and burrs.

WANG Ben1, DUAN Yugang1, LI Jinjian1, GAO Kan2
DOI: 10.16080/j.issn1671-833x.2017.07.105
Fiber Bragg grating (FBG) is proposed to embed in the composites to monitor the variation of strains and
temperature, however, the influence of embedment on the sensing performance is not clear in the current studies. In the process
of embedment, the angle between OF (optical fiber) and carbon fiber in the adjacent prepreg will generate the internal stress,
which affect the sensing performance. For the sake of the investigation on this influence, the composites embedded the varying
angle of OF is prepared and tested under the variation of strains and temperature to observe the influence on the sensing.
Obtained results indicated that the angle of OF will affect the sensing performance inculding strains and temperature. In the
inspection under the temperature, the degree of fitting for the sensing curve decreases with the increasing angle. Also, the deviation
of the data measured by OF and strain gauge increases with the angle, implying a bigger deviation.
