A special control method is put forward in this article to achieve the consistency with the mechanical properties of engine.
However, the mechanical properties of the motor and the engine is very different, as a result, the handling characteristics of fuel automobile and the ELV is very different.
This characteristics of the motor makes it have better mechanical properties than the engine, but all kinds of motor control technology set up based on this feature can’t transform motor into mechanical properties similar to engine.
When ELD starts, the speed of the motor is very low, according to the mechanical properties of the motor, torque offered by motor will be very big.It is necessary to reduce the electromagnetic torque, so that Hope ELD and fuel achieve the same effect when the car starts, which can be achieved just by the armature voltage regulating method.
Making the mechanical properties of the motor similar to the fuel engine becomes available, which makes ELD further replace fuel truly and makes it possible to make full use of advantages of electric vehicle, such as no pollution, saving oil resources, reducing the cost of driving training and so on.

ANOVA also can be used to determine the contribution of each factor which influences the properties of the product.
Meanwhile Table 1 is shows the main materials properties.

So that by used simultaneous optimization and overall analysis based on both properties, a set of factors which is considering both properties can be determined.
Meanwhile for flexural strength the result shows that all factors affect accordingly.

Design factors such as mandrel diameter, punch nose radius, deflection corner radius, gap width in annular direction, and frictional conditions are applied to the present study by simulation.
The influence of these design factors on the force requirement during the forming operation and the pressure exerted on the tooling such as the punch and mandrel is investigated and the simulation results are quantitatively summarized in terms of pressure distribution, force-stroke relationships, and maximum force requirement, respectively.
Thus, other design factors except the gap height are adapted as design parameters in this study.

The extension of heat affected zone is an important factor.
Another phenomenon which should be dealt with is the change of properties due to radiation.
Of course the real capabilities of the techniques and the application parameters have to be taken into account, and these are considered as objective factors.
Intensive steps should be taken to learn the actual mechanical properties, and the integrity has to be verified by suitably selected non-destructive testing procedures.

Zhenhua Zhang, et al. put forward the research ideas and methods of dynamic deformation and early-warning monitoring indicators in excavation process based on design safety factors and failure mode, and applied them to determining the deformation and early-warning monitoring indicators.
External Deformation Property.
Deep Deformation Property.
The overall deformation is mainly affected by seasons and rainfall, in a stable condition.
Plastic strain contours and lateral deformation contours of the model are separately shown in Figure 3 and in Figure 4, and lateral deformation curves with different reduction factors in Figure 5.

The residual Mn and Fe as impurities may have a bad influence on mechanical properties of Cu-30Ni alloy.
Therefore, over-added Mn and Fe incline to deteriorate the microstructure and mechanical properties.
Therefore, the use of unclean raw material and contaminated processing environment with iron chips can bring negative effect on mechanical properties.
There are a number of factors that affect the overall performance.
Among these are the volume percentage, shape, location, mechanical properties and the compositions of inclusions.

As far as CB-filled CPCs are concerned, it is desirable that conductive percolation thresholds decrease as low as possible because high CB concentration causes difficulties in CPC processing and worsens mechanical properties of CPC.
In past ten years, one type of ternary CPCs consisting of two immiscible polymer blends and CB is attracting great attention because it has been proved to be feasible to effectively reduce the percolation threshold, and accompanied with other excellent properties as well.
The regarding results agree that the distribution of CB in polymer blends has very important influence on the electrical conductivity and other properties.
Many previous studies have clearly demonstrated that the factors affecting distributions of CB or other filler in two-phase polymer blends are excessive and very complex [5], in which thermodynamic parameter like surface energy of each component in the blends are the most important one among the factors.
As is well known, the factors affecting distributions of CB or other filler in two-phase polymer blends are excessive and very complex [5], and it is very difficult to give a completely accurate prediction of the distribution. wetting coefficient (ωa) suggested by Sumita at al [9], based on interfacial tension data, was extensively and more successfully used to forecast the distribution in many related literatures. wetting coefficient ωa can be calculated as follows according to Eq. (3)

Therefore, it is necessary to probe into the character and effect factor of multi-physics field in high speed milling cutter.
Under the influences of experiment conditions and random factors, it will not only be time-consuming effort, but also hardly get accurate results to research the performance of cutter and effect factor by the means of cutting experiment, finite element analysis of multi-physics field can rapidly acquires the distribution of cutting heat, stress and deformation in cutter8.
Modal Analysis of High Speed Ball-End Milling Cutter The modal property directly affects dynamic performance of cutter, and the effective modal shape and natural frequency are sensitive to structure and local damage of cutter.
Analyze the influence of the structure on modal property of cutter, results are shown in Fig.3.

The prepared copolymers possess the properties of elastomers.
Due to these properties, these materials have potential usage in microelectronics devices and medical devices.
Because low thermal and mechanical properties of polyethylene caused such a search [6-8].
Drug-loaded micelles without deformation are important for tissue engineering to carry drugs within the body or growth factors to protect the body from infection or tissue regeneration.

So the mechanics property of superalloy is concerned with the temperature of workpiece, and the temperature rise is one of the key factors which affect the performance of superalloy tube, moreover, it can lead to variety of mechanical properties.
During hot process, the temperature has a significant influence on structural state and mechanical properties of billet.
Other mechanical properties are temperature dependent.
Based on the above FEM model, this study is to determine the relation between technological factors and the temperature rise, extrusion force.
