This study presents a brand new concept in contrast to that of the conventional mechanical toy robots on the market.
In addition, counterbalance of the robot while walking is affected by the location of the center of gravity of the trunk and the distance between the feet.
It became clear that the stability of the walking robot was determined by many factors, and difficulties may arise if any of these factors is changed.
The material and properties of each component was specified and the crank rotation speed was set at 20rpm.

Study on Lubrication Properties of Emulsion for Aluminum Cold-rolling Wenxia Wang1,2,a,Ping Liu2,b and Guoqiang Yao2,c 1Shanghai University ,School of Mechanics Engineering and Automation, Shanghai 20072,China 2Shanghai Second Polytechnic University, Electrical and Mechanical Engineering Faculty, Shanghai 201209, China awxwang@meef.sspu.cn, bliuping@meef.sspu.cn, cgqyao@meef.sspu.cn Keywords: Aluminum cold rolling ; Emulsion lubrication; Lubrication model.
This paper’s work is to illustrate the mechanism and properties of emulsion lubrication.
Otherwise, stability is the most important factors to keep the application period of emulsion, and whether water and oil is emulsified well depends on the emulsifier.
In the earlier studies, much work was done on the viscosity of lubricant, but viscosity could not explain the lubrication properties of point contact lubrication.
The factors which lead to film failure includes roughness, non-Newton lubricant and temperature.

Effect of VC/Cr3C2 additions on microstructure and mechanical properties of WC-16TiC-xTaC-10Co Ultrafine Cemented Carbides Chongcai Zhang1, a, Quan Wang1, b,*, Qunqun Yuan1, c and Long Wang2, d,* 1College of Material Science and Engineering, Xihua University, Sichuan Chengdu 610039 China 2Zhongshan Torch Polytechnic College, Guangdong Zhongshan 528436 China azhangchongcai@sina.com , bwqword@126.com, cxhdxyuanqunqun@163.com , dkingkingv@163.com Keywords: Grain Growth Inhibitor; cemented carbide; property; microstructure Abstract.
The physical properties and the micrographs of samples were detected.
Effect of VC/ Cr3C2 on mechanical properties.
So the main factor that affects coercivity is inhibitor additions with the other production conditions and process unchanged, Hc∝1/dwc, the higher coercivity, the tinier grain size, this suggest that VC/ Cr3C2 inhibite the grain growth, but this coercivity increased with the content of Cr3C2 increasing does not agree with the theory of VC/ Cr3C2 inhibite the grain growth in WC-Co as a large amount of (W, Ti, Ta)C in this cemented carbide[1].
Effect of WC particle size on the microstructure, mechanical properties and fracture behavior of WC-(W, Ti, Ta)C-6wt%Co Cemented carbides.

As the test on tower is quite complex, and the factors affecting the tower behavior are more the experimental researches on the mechanical behavior of tower system were very few at home and abroad in the past.
Therefore, it is particularly important to analyze the mechanical behavior of tower by testing and provide pertinent references for the tower design [3].
The mechanical properties of steel are shown in Table 1.

The hysteretic curve of this kind of tower presents anti-S shape, and the plastic deformation and energy dissipation capacity is poorer, so how to improve its mechanical performance is still studied.

As addition of SiC, the intragranular and intergranular location of the reinforcement nanophase improves the physical properties by affecting the local tensile and compressive stresses at the boundary between the two phases.
This specimen has maximum mechanical properties such as hardness, fracture toughness and strength.
Mechanical properties of Al2O3/5 vol.% SiC.
For coarse grain size specimens, fracture mode of transgranular type was not affected to large grain size because of toughening factors such as crack deflection and crack bridging could not be occurred.
As the sintering temperature increased, mechanical and wear properties were decreased.

The main Parameters affecting the Structure The FB100 foamed asphalt testing machine which was jointly developed by Chang'an University and Xi'an Road Construction Machinery Co., Ltd was used in this test.
Considering two factors of the expansion rate and the half-life, the foaming conditions would be chose as follows: atmospheric pressure 300kpa, water pressure 400kpa, asphalt temperate 160℃, foaming water 2%[11].
Figure 4 Goaming characteristics be affected by volume ratio Expansion rate half-life Expansion rate half-life Figure 3 Foaming characteristics be affected by inner-diameter The changes of foaming properties because of the inner-diameter were drawn in Figure 3.
The changes of foaming properties because of the volume ratio were drawn in Figure 4.

Properties of Elastomeric Adhesive Composition Based on Chlorinated Isobutylene Isoprene Rubber Obtained by Mechanochemical Halide Modification K.V.
In the work the basic properties characterizing adhesive, protective and paint coatings have been studied with the main focus on dependence of the materials properties on chlorine content in chlorinated isobutylene isoprene rubber used as polymer basis of adhesive compositions under investigation.
Based on the study results of the technological properties of elastomeric adhesive composition, the optimal adhesive composition has been recommended.
Nowadays, the need for elastomeric adhesive compositions, which have a specific set of properties providing their operation in extreme conditions, is constantly increasing.
Due to its high resistance to impact of physical and chemical factors rubber goods based on chlorine-containing rubbers are widely used in construction as adhesives, damping and materials [3].

Indentation-derived tensile properties of ASTM A335 P91 pipeline.
From the results, it was concluded that indentation could be used effectively as a direct inspection method of welded joint considering various in-field environments and constraint factors.
Because the pipeline has been used for over 15 years, it could be affected by the various environmental conditions such as corrosion, mechanical shock, and other material degradation factors by long-term operation.
Accordingly, materials could have mechanical properties different from those of new materials.
From the results, it was concluded that the pipeline could be operated continuously in terms of mechanical properties.

In the spring after clay thawing, sticky lower and internal friction Angle increases, make mechanical properties of soil before and after freeze-thaw changes, directly affect the anchor pile bearing capacity[2,3].

This paper reports the fabrication of a tunable radio-frequency (RF) inductor and discusses the parameters that influence the quality factor (Q) of the inductor.
Fig. 1 The structure of the inductor Theoretic Analysis The main factor that affects the Q value of the inductor is the large loss caused by various devices’ parasitic effects, which can be expressed by certain equivalent components, as shown in figure 2.
When micro mechanical method is adopted to remove the substrate under the inductor and form suspension structure, all the parasitic components , Csub, Rsub and Rse can be ingored.
For the inductor which is applied in the RF communication, skin effect of conductors will dramatically change conductive properties of conductors with the rise of frequency.
SU-8 is becoming more and more favorite photoresist due to its excellent coating planarization and processing properties as well as its mechanical and chemical stability.
