In this paper, with the Basic strategy of using human body model for conduct driven design of Product’s Shape Factor, in order to achieve the product model design and modification, author changed designer’s traditional way of the direct processing Geometric model to the way by operating human body mode; as shown in Figure 1, on the one hand, it is to improve the usability of software and design efficiency, on the other hand, it will facilitate the constrained problem solving of the multiple coupling.
Product Model Designer People Model (a) Traditional product ergonomics design (b)Ergonomics design driven by human model Fig.1 Comparison between product ergonomics design methods Principles of human body model’s driven design.The essence of the product ergonomics design driven by human body model is a mapping process, which is mapping some of the requirements in man-machine interaction, such as force and contact properties, into the design elements products, such as dimensions or surface shape.
In most cases, product ergonomics dimension is not completely independent, the dimensions will be restricted by each other and affected by f other non-ergonomic dimensions, therefore, the final solution is usually a holistic optimization results.
Energy optimization is surface design method based on the physical properties, the surface shape with minimal elastic deformation process can be solved through the program, and thus, the surface smoothness can be naturally guaranteed.

Magnetic Properties of M-type Hexaferrites 2.1.
The structural properties of M-type hexaferrite depend on many factors like preparation methods, sintering temperature, time, chemical composition and amount of substitution etc.
Magnetic Properties of M-type Hexaferrites.
Therefore, resins which shrink a lot or harden unevenly should be avoided, and some resins also generate extreme localized heat as they set, which could affect the magnetic properties [90].

Abstract: The soil surrounding of the pile will be compacted during static sinking-pile, higher pore water pressure will arise, which will cause compaction effect and affect the surrounding engineering environment in the soft soil area.
The engineering properties of soil have a great change compared with the state before pile sinking. 4) Along with the gradual disappearance of excess pore water pressure in the soil around the pile, soil would consolidate again, and making the pile side under the effect of negative friction resistance. 5) With pile-sinking, the soil squeezing effect would cause cracks around buildings, underground pipeline, and so on. 2.2 Cause analysis for the adverse effects of static sinking-pile The main cause of the adverse effects of static pressure pile sinking on the environment around the pile includes the following two aspects: First, when piles sink into soil and squeeze the equivalent volume of soil, soil is disturbed.
Making a comparative analysis between poled pipe-pile and tapered pipe-pile which is not difficult to find out that the cone angle is not only have an important influence on bearing character and settling properties of tapered pipe-pile, but it is also the key factor of the difference between the two pile types.

In addition, springback is affected by process parameters.
Using plastic deformation theory, Li et al. [6] established the theoretical model for springback of tube bending considering tube specifications and material properties.
In previous reports, most studies are usually neglected the variation of elastic modulus with the plastic deformation during tube bending, which will affect the springback prediction accuracy, especially for the high strength 21-6-9 tube with high ratio of yield strength to elastic modulus.
The detailed FE modeling process, mechanical property parameters of high strength 21-6-9 tube, process parameters and so on can be seen in the references [13, 14].
Results and Discussion Using established FE model combined with single factor method, the effects of process parameters on springback of high strength 21-6-9 tube during rotary draw bending were investigated considering variable elastic modulus.

Because dry-film coating method affects the lube uniformity and thickness, the spray method was used to coat the lube to the steel sample, then drying on the air.
The uniformity and the thickness of coating layer become the important factor for the good performance of dry-film.

Bubbles in a tube/vessel affect the flow in that tube/vessel.
The diameter, D, of these tubes may be sized relative to one another, in accordance with (5) where αD is the scale factor or design rule (e.g., for parent and daughter tubes of same size, αD =1).

Another important requirement to outriggers structure consists in limitation of their mass and moment of inertia so that these characteristics would not affect the test results.
The mentioned values are determined depending on vehicle’s stability factor (SF) which in turn depends on the center of gravity height and width of the vehicle.
It was essential to properly define and set physical and mechanical characteristics of the materials that the outriggers were planned to be made of, as these parameters would be crucial for the faithful reproduction of the behavior of the outriggers under the influence of force action.
As it will be described further, necessary properties of stiffness and bearing capacity for outriggers can be achieved by the use of such materials as aluminum, high-alloy steel, titan or composites.

However, the solids fraction should be very high, approximately 45 - 65 vol-%, to ensure adequate green part properties [74, 75].
Hence, a good compromise has to be found between the reactive properties of the suspensions and their viscosity and solids loading.
