16 Fabrication of Microfluidic Chip Mold Based on Electrochemical Etching and Micro-Electroforming
DU Liqun1,2, LI Qingfeng2, LI Yuanqi2, ZHAO Wenjun2
DOI: 10.16080/j.issn1671-833x.2017.17.016
The performance of microfluidic chip mold is subject to the adhesion strength between electroforming
layer and substrate in micro-electroforming process. In order to remedy this defect, a novel, lithograph-based method
combining through-mask electrochemical etching and micro-electroforming is presented, by which the nickel double cross
microfluidic chip mold with high adhesion has been successfully fabricated. According to experimental studies on process
parameters, not only optimal parameters were yielded, but also issues like the failure of interfacial delamination due to
pickling and lateral corrosion caused by electrochemical etching were further solved. The interface adhesion strength can
be determined by shearing strength between electroforming layer and substrate so that the influence of pickling and etching
on interfacial adhesion strength can be analyzed quantitatively. The results of the experiments indicate that the shearing
strength after pickling (25℃ , 20s) and etching(30℃, 5min) is increased by 98.5% and 203.6% respectively, compared with
that of untreated samples. Furthermore, the shearing strength of samples etched is 53.0% higher than that of samples after
pickling treatment. The method presented in this paper can effectively improve the adhesion strength between the electroforming
layer and the substrate. Additionally, the service life of microfluidic chip mold can be prolonged.

YIN Weilong1, SHI Qinghua2
DOI: 10.16080/j.issn1671-833x.2017.17.024

The most important technical characteristic of morphing aircraft is that the wings remain smooth, continuous
and seamless during deformation. Morphing skin technology is the key to ensure this technical characteristic. In present
paper, the current situation and future trends of morphing skin materials and structures are summarized in detail in the form
of deformation and chronology. The stiff skin like fish skin was used for morphing skin in the early stage of morphing aircraft
and the composite structure is designed to have adequate elongation strain in the current studies. In a word, the composite
structure tends to show more potential to be as morphing skins.

ZHANG Mingde, LI Yage, WU Yanbin, XU Zhiwei
DOI: 10.16080/j.issn1671-833x.2017.17.049
The relationship between recovery stress and temperature of shape memory alloys in static heating and
dynamic heating condition has been researched. In former condition, an iterative method for constitutive model, which
could predict recovery stress effectively, was raised. The limitation of traditional model in later condition has been expressed
as well. Therefore, an efficient method called mean rate interpolation has been proposed. With this method, the
result of SMA’s recovery stress in dynamic heating condition can be calculated accurately, whose relative error is less than
10%.

66 Modeling and Simulation of SiCp/Al Composite Under Working Conditions
GENG Kun, ZHANG Jie, ZHANG Di
DOI: 10.16080/j.issn1671-833x.2017.17.066
This paper developed a parametric modeling program to simulate SiCp/Al composite based on the finite
element method. This modeling program developed by Python script in Abaqus, was able to achieve the visualizations of
the modeling process by implementing graphical user interface (GUI). The parameters of particles like sizes, shapes, volume
fractions and distribution are controllable in this user interface. In addition, a 3D representative volume element (RVE)
was created for studying the microstructures of SiCp/Al composite. In order to simulate the composite’s elastic-plastic
deformation process as well as its crack generation and propagation, different deformation behaviors were considered in
the simulation, including the particle’s elastic-brittle failure, the matrix’s elastoplastic-damage, and the interface’s tractionseparation
behaviors. To investigate the relationships between the microstructure and the mechanical properties of SiCp/Al
composite, this paper built the finite element models with different particle volume fractions under different working conditions.
Firstly, the impacts of particle volume fractions of 7% and 14% on the composite’s deformation and damage behavior
were studied through out the tension process. Secondly, for the 7% particle volume fraction model, the compression process
was simulated and compared with the tension process. Finally, the mechanism of the composite’s deformation and damage
under various loads conditions was analyzed. It had been proven that this parametric modeling program was feasible
to build the particle reinforced metal matrix composite model based on its microstructure, and was of great significance in
studying the strengthening and toughing mechanism of composite as well as the relationships between the microstructure
and mechanical properties.

75 Research on Hollow Fan Blade Tip Welding Failure in HCF Test
DOI: 10.16080/j.issn1671-833x.2017.17.075
For the unexpected tip failure of hollow fan blade HCF test, the stress distribution test, vibration simulation
and crack analysis were done. The test results indicate that the failure region is not the high stress region, and fracture analysis
indicates that the crack initiates from the welding area of the duct in the blade tip. Validation test on the blades without
the tip welding shows that the failure is induced by the welding defect in the blade tip duct. Based on the fatigue analysis
and test validation, the failure occurs by improper welding method selection and welding process control in the manufacturing
process. Consequently, the improved process is applying the EB welding in manufacturing and CT inspection.

91 Research on Factors Influencing Assembly Accuracy of Composite Laminates
ZHANG Tingyu, ZHONG Yang, YAO Wenhao
DOI: 10.16080/j.issn1671-833x.2017.17.091
Errors cannot be avoided in the process of machining and assembly because of the restriction of the manufacturing
ability, hence the assembly accuracy of products cannot be guaranteed. Different from the metal material, composite
material possesses anisotropy characteristics. Therefore, the control of the assembly accuracy of composite laminates
is more difficult. For the problem that it is difficult to guarantee the assembly accuracy of composite laminates, the factors
influencing the assembly accuracy of composite laminates was analyzed. After the parts machined in the same batch were
numbered and recombined with other parts, the effect of the combinations of different parts on the assembly accuracy was
analyzed using finite element method (FEM). For the assembly composed of multiple parts which can be assembled in different
orders, the effect of assembly sequence on the assembly accuracy was also analyzed. The research realizes that both
the different combinations of parts and the different assembly sequence have impacts on the assembly accuracy of the composite
laminates. Thereby, it is very important for improving the assembly accuracy of composite laminates to predict the
assembly accuracy and to optimize the combination and assembly sequence before the parts are assembled.

Indirect measurement is conducted with a reflectivity measurement device to determine the laser light
absorptivity of the commonly used metal powders and metals bulks in laser additive manufacturing technique. The effects
of the size and the shape of metal powders on the laser light absorptivity are investigated, and the laser light absorptivity
of metal powders and metal bulks to 1064nm laser light and 532nm laser light is measured respectively. The measurement
results show that powders with better sphericity and bigger particle sizes exhibit higher laser light absorptivity, and the laser
light absorptivity of metal powders and metal bulks to the 532nm laser light is greater than to the 1064nm laser light. The
measurement results can provide basic experimental data for the laser additive manufacturing of these metals.

In-situ TiB2/Al composites have extensive application prospect in the field of aeronautics and astronautics
due to their outstanding mechanical properties, such as low density, high specific strength and high specific modulus. Grinding
experiments were conducted to analyze the grinding performance of in-situ TiB2/Al composites in different grinding parameters
by using single alumina wheel, white alumina wheel, and cubic boron nitride wheel respectively. The influence of
grinding wheel, wheel speed, workpiece speed, and depth of cut on surface roughness were investigated. Moreover, the topography
of grinding surface, grinding chips, and the wear on grinding wheel were observed to analyze the surface forming
mechanism of in-situ TiB2/Al composites. Finally, the optimal grinding parameters were selected based on the experimental
date. The research contents and conclusions will provide theory support for in-situ TiB2/Al composite grinding process.

DOI: 10.16080/j.issn1671-833x.2017.17.107
To deal with the poor operational and low reliability existing in the tradition lifting sling, a self-leveling
lifting sling has been developed. It can automatically regulate the movement tendency of the main lifting point based on the
current pose of suspended cargo, to achieve leveling suspended cargo; Meanwhile, it also can automatically calculate the
barycenter of suspended cargo to adjust the final postion of the main lifting point, thus reach the suspended cargo leveling.
Eventually, the design of lifting sling control system is based on these two above control strategies.
