Introduction The magneto-rheological fluid made by dispersedly dissolving the soft magnetic material of micrometer size into carrier liquid of low permeability is a kind of material, the rheological property of which will change rapidly under the action of an external magnetic field and it shows some mechanical properties that are resemble to solid’s.
Building, Training and Testing of RBF Network Model The number of neurons in the input layer of the RBF network model depends on the influencing factors of the MR mount damping force, and through the above analysis it is known that the number is 3.
Because the units of the collected data are not consistent, in order to accelerate the training speed of the network, the data must be dealt with [-1，1] normalization and reverse normalization to prevent the difference between the data too large, meanwhile, also prevent some neurons showing the status of super saturation to affect the training process.
Fig.4 Comparison of indicator features of Fig.5 Forecast performance of RBF MR mount neural network Conclusion The output damping force of the MR mount on the automotive engine is influenced by a number of factors which have complicated correlations with each other.

Tibia bone sample constraints combined with the unraveling of the ligament knot were identified as primary factors for low pull-out loads for the porcine ligament tests.
A composite of PLLA and βTCP is postulated to have different properties than pure PLLA.
An ideal ACL anchor will maintain its properties for the first six months after implantation; begin to degrade after 6 months; and fully degrade or contain insignificant trace amounts after approximately 12 months.
Factors that may affect degradation include: specific implant material used, implant geometry, site of implantation, sterilisation method and crystallinity [10].
The differing location may have adversely affected the results.

Human body, as an entity of its subsystems should be regarded as a whole and not as a manifestation of modular structures that are independently acting, so that the morpho-functional factors generating the body motions are integrated in this system by means of the analysis using reintegrating synthesis of the environment interaction feed-back reactions.
The study of complexity in gait has shown that pathological gait, on the other hand, can be either too periodic and predictable, or too random and disordered.[3] Theoretical aspects of sound, noise and vibration effect on human body A lot of sounds, many of them considered as noises, from the environment determine changes of the human behavior, and if they are combined by visual stimuli, they may finally affect the stability, balance, gait or jumps performed by the human factor.
Hearing loss can be due to aging, exposure to loud noise, medications, infections, head or ear trauma, congenital or hereditary factors, disease processes and many other causes.
For this reason it is very important to identify it in due time and prevent it by acting as much as possible upon the environmental factors.

This type of stainless steel exhibits better mechanical properties, good fabricability, weldability and excellent resistance to general corrosion, so it is widely used in many industrial applications.
The use of shock waves is very effective to improve the mechanical properties of metallic materials, such as fatigue, corrosion and wear resistance [6-11].
LSP is very effective to decrease the stress corrosion rate and improve the material stress corrosion properties [13-15].
This is beneficial to reducing the stress corrosion and improving the material properties.

The thermo-mechanically affected zones have fine granulation.
A shear test on a tensile test machine, without any guide device, has been performed on the specimens T1 - T5, with the results 60.80 – 167.51 MPa, depending on the parameters and specific factors.
Around the pin, there are both the thermo-mechanical affected zone and the heat affected zone, both distinct from the weld metal.
The results of the shear test are in the range 60.80 – 167.81 MPa, depending on the parameters and factors or conditions.
This result proves the significant and positive effect of FSP on the structure and mechanical properties of the previous FSW.

Introduction The control of pulp pH value is a difficult task that has four main causes: the characteristic of large time delay is usually caused by the factor that large reaction vessel make the reaction is not sufficient; the inherent and strong nonlinear characteristics of neutralization reaction is mainly caused by the negative logarithm of PH value , the feature make some of the traditional control strategy is no longer applicable; time variant property is the dynamic characteristics of measurement sensors that is easily affected by the environmental changes, such as temperature, pressure, electrode cleanliness; measurement sensor is easy to scale or glue solid attachments that makes the measurement results has a large deviation compared with the real value [1] ,So the control system of pH value has great research value.
To select the optimum electrode need to take into account many factors, such as chemical composition, velocity, temperature, pH value range and pollutants, etc.
In contrast, the glass electrode produces acid error when the pH value of solution is less than or equal to 1, this is because the ratio of acid and water is high, the glass film and the electrode response will be affected[3]
Control method of pH value The control of pH value has serious non-linear and large time delay characteristic, and the measurement of pH value is prone to be interfered by a variety of factors, so traditional feedback control algorithm is difficult to achieve control requirements.

In general, wrinkling may be affected by various factors including material properties, punch and die geometry, blank geometry, holding conditions, interface friction and lubrication state.
Determination of Design Factors The design factors must be determined in the first stage of the simulation.
Selection of Material The material properties plays an important role in any sheet metal forming due to spring back operation.
The material properties used in this analysis is shown in table 1.
Each setting has the different types of mechanical behavior that influence these defects.

Its components, such as guide vane, runner blade, labyrinth, pivot ring, etc., are known to be affected by cavitation or combination of cavitation, erosion, and corrosion, as illustrated in Fig. 1[5, 6].
However, since the cavitation erosion is such a complicated physical phenomenon, the experiment is impossible to treat all factors which may affect the cavitation.
The iterative solvers are considered converged when the residuals have been reduced by a factor of 10-5.

For pumping concrete, its fluidity and interaction with circumstance when flowing in pipes are important parts of many influential factors, which affect the validity and high effectiveness [1, 2].
Since the distribution of interparticle forces is affected by many factors such as particle's position, shape, and size, their measurement or numerical estimation is impossible at present.
To simulate the motion of stiff sphere particle in a viscoplastic body, cylindrical suspension elements with viscoplastic properties are constituted between a pair of particles when they are closer than a certain distance.
Though numerical simulation of Bingham model is widely applied in petroleum industry, chemistry industry and mechanical industry, Bingham model has not effectively used in pumping concrete.
