The design and manufacture of the coal mine rescue robot are affected by various of factors, such as whether the structure could adapt to the complex underground environment, whether lightweight robot could have higher strength, and whether the materials were low price and easy processing.
The mechanical analysis of the rescue robot.
It can be seen that the brackets’ mass have reduced but have better mechanical property.

ZnO has unique properties with variety of nanostructures such as nanowires, nanoflakes, nanoparticles and nanobelts [3].
CNTs act as a catalyst to improve the electrical properties of the DSSC.
Table 1: XRD properties of ZnO based with different concentrations of MWCNTs.
The electrical properties listed in Table 2 includes short-circuit current density, Jsc, open-circuit voltage, Voc, fill factor, FF and power conversion efficiency, PCE or η.
Feng et al. (2005) reported that MWCNT also influences the PCE of the DSSCs due to the fluctuation in Jsc and Voc where they affecting the amount of dye adsorb inside the cell and recombination of electron and hole [15].

Different MIC mechanisms can be simultaneously or alternately occuring on various materials, where a complex boundary layer of corrosion products, bacterial cells and other environmental factors are present on the surface.
Thus, problem of the SRB-assisted hydrogen damage is of special importance for steels of increased strength, since the susceptibility to hydrogen embrittlement increases with increasing mechanical properties of the steels.
Cathodically evolved hydrogen in sterile medium insignificantly decreased its mechanical properties after 2 months of hydrogenation.
King et al. [22] compared the FCGR measured in sterile seawater and in the presence of biological or non-biological sulphides and established the corresponding acceleration factors DK.

Many variables are involved in the prediction of the optimum rolling schedule in terms of productivity, plate geometry, and final properties, each of which will be associated with its own errors.
The Scunthorpe Plate Mill example in Fig 1 is of the off-line set-up type; typical usage is to scope a prospective order and devise the optimum schedule to achieve the required mechanical properties.
(a) Yield strength (b) Tensile strength Figure 2: Mechanical property predictions from the Scunthorpe Plate Mill model on CMn, HSLA(Nb,V) and intercritically-rolled steels [2].
Purely empirical factors to adjust the predictions from those of wholly austenitic deformation have been applied for plate rolling, but this does not enable a proper understanding of the effects of changes to the rolling schedule or steel chemistry on the microstructure and mechanical properties.
For mechanical properties, these are smaller than the standard A80 strip tensiles, which is known to influence elongation.

Therefore a vertical additional force would be affected on the mine shaft liner and the vertical additional force would be the main factor to cause breakings on the mine shaft liner.
Mechanical potential erosion theory.
Mechanical erosion reduces the potential shear strength of the interface.
According to the change of rock property and structure, it can be divided into two sections.
Shaft in the operation period mainly is affected by the aquifer drainage.

Introduction The diamond-like carbon (DLC) films present unique mechanical properties because of their low friction coefficient and self-lubricate characteristic [1, 2].
Friction Models and results Three dimensional structure of DLC films is important in determining their mechanical properties.
The results show that the prove graphite transformation is a key factor of the low friction coefficient for DLC film.

And the most important requirements of a good separator include the following: good mechanical properties, minimal electrolytic resistance (good conductivity of ions), electric insulation, and chemical resistance to degradation by electrolyte or the active electrode materials.
Polypropylene (PP) membranes have been commonly used in secondary lithium batteries owing to their high mechanical strength and proper thermal barrier property.
The relative percentages of elements were calculated by integrating peak areas using atomic sensitivity factors.
The S2p signal was used rather than S2s; the Kratos library accounts for the different angular asymmetry factors for s and p orbitals.
Table 1 lists the PP and modified PP membrane data obtained by XPS, calculated from the atom peak areas using atomic sensitivity factors.

Introduction Car shield’s structure immediate influence pedestrian is protecting the forehead crash safety performance, its mechanical property (for example yield strength), the stock thickness, the hinge position distribution and so on various aspects factor has the very important influence to the result.
Because the pilot area various spots’ structure is different, the different impact point will cause the different test result, it will thus affect final whole grading.
It discovers in each small district the hazard point and carries on the partial structure the revision, avoids because of the partial hazard point existence, but affects to the overall pedestrian protects the forehead crash effect.
Purpose meaning According to related literature [4~5], the pedestrian forehead crash injury value with Car shield’s mechanical property, the stock thickness, bulge hard object’s underneath position, impact point and this spot factor and so on gap relevance is very big.

The moment of inertia caused by the whirling of rotation parts is called gyroscopic moment which affects the critical speed of the rotation[6].
The damping affects the dynamic deformation and the amplitude while the rotary occurs under in the critical speed of rotation.
Parameters such as material properties, the stiffness and the damping, are shown in Table 1.
