Because of its "sealing ring thin-walled, large deformation, precision" on the whole, the development of metallic sealing rings are extremely difficult, and the design analysis process is affected by many factors, design analysis affected by many factors.
Under high temperature, the strength of the material is still very good, its oxidation resistance, fatigue, fracture toughness, plastic and other comprehensive performance are very good also, the basic mechanical properties parameters are shown in Table 1[3].
These factors have a lot of uncertainty and is unable to avoid, Therefore, are considered in the analysis is very difficult.
This article selected the plane that W metallic sealing ring contact with the top and bottom of flange as the target surface, Considering the influence of friction factors, choose the coulomb friction model, According to mechanical design manual [5] standards, selected the friction coefficient of 0.15.

The higher hardness value of 54HRB was affected by Cu content due to the good mechanical properties of fasa CuAl2.
Microstructure and mechanical properties were identified to show the effect of additional Cu content.
Other disadvantages are coarser grain size and inferior mechanical properties.
Different amount of in CuAl2 phase caused significant differences in mechanical properties.

The corresponding prevention measures to different influencing factors were presented in the end.
Mechanical Analysis on the Substructure Stability due to Landslides and Mudslides Bridge pile foundation general would not directly influenced by external force, but if bridge pier was affected by an external force such as landslide thrust, the internal force of pile foundation inevitably increase.
Fig.1 Typical section of bridge pier column Fig.2 Pier column’s force diagram impacted by landslide thrust and debris flow pressure Usually, landslide affects pier on one side, but debris flow had fluid properties, so it affects the pier on both sides, the bending moment diagram of pier subjected to two kinds of external force as shown in Fig.3.
The lack of soil around the pile which caused by soil erosion could be an important factor affecting the pile safety, shown in Fig.4.
The bearing characteristics, internal forces, displacements and other characteristics of the pile were influenced by the degree of soil erosion around the pile, the properties of soil around the pile, the material and size of the pile and other various complex factors.

In Figure 1(a), 'compression touching' represents a perceptual indicator involving various factors, such as fabric structure, yarn material properties, and surface characteristics.
A simplified model was adopted to exclude the variable factors.
The finding indicates the need for a closer examination of the factors that influence the magnitude of such inherent stress.

The phenomenon of the factors that influence the dilution that occurs between the filler material and the base material and the technological processes possible to achieve efficient plating.
It should be minimal, so the mat made ​​to be as close to the weld material, and to obtain specific properties of the structure and the selection of particular filler.
Main functional properties of the plating obtained by welding a drum charging The area tested Mechanical properties Rp 0,2 [MPa] Rm [MPa] A [%] Z [%] KV-46 [J] HV10 Material base (MB) 498 675 23,2 58,4 57,5 197 Heat affected zone (ZIT) 424 593 18,0 35,0 52,8 23,7 Filler material (MA) 590 868 25,8 35,8 42,9 245 Basic material: AISI 410; Filler material: Inconel 625 Fe.
There is a substantial increase in the phenomenon of dilution which means reducing the functional properties of the torque resulting from the coating.

Growing expectations of customers regarding the quality of hot rolled products is a driving force for a better understanding and control of the different factors responsible for this non uniform process and its impact on the final properties.
Impact of coil cooling conditions on properties Several authors have reported data showing the influence of coil cooling conditions on mechanical properties [5, 7].
Typically, for CMn and HSLA steels, pearlite softening and precipitation strengthening occur during coil cooling and affect the homogeneity of final properties.
It allows assessing the final microstructure and mechanical properties from the process parameters.
Indeed, one can see a slight decrease of mechanical properties at both extremities of the coil.

This is due to the fact that changes in the concentrations of alloying elements within the grade composition strongly affect their properties [4-6].
This leads to instability of the structure, basic mechanical properties and wear resistance, which affects the service life of castings that can differ by 2- 3 times for the same operating conditions of pumps [7-10].
The microhardness and the volume fraction of carbides affect the properties most strongly.
Niobium and boron also affect the properties of cast iron.

In this paper, the CMP mechanism and the effect of abrasive on SiO2 dielectric were analyzed; the different factors of affecting the CMP were analyzed.
CMP is an integrated process including chemical effect and mechanical effect[4].
It takes the function of mechanical grinding. ②Transmitting material.
To get the high remove rate and control the metallic ion content of the slurry, pH conditioner should have similar property with NH4OH but no volatility.
Summary The removal rate and surface perfectibility of dielectric film CMP are influenced by many factors, such as pH value, abrasive concentration of slurry and slurry flow.

In this regard, there appeared new dependencies including various technological factors.
This zone differentiates the mechanical properties of steels when they are heated.
Talantov noted that temperature is a controlling factor affecting the density of dislocations and, consequently, the resistance of a metal to plastic deformation.
Along with such technological factors as the tool feed S, cutting depth t, as well as other factors causing a temperature increase in the cutting zone, it is the cutting speed V that has the greatest influence on the temperature component and on the formation of the surface microgeometry.

Determine the optimum sintering temperature and optimum whisker content, when the mechanical properties of the composite materials are the best.
Stomata are stress concentration sites, and often lead to reduced mechanical properties.
The main factors that impact flexural strength of whisker reinforced material are: the type of whiskers whisker content and sintering temperature, etc [3].
Generally the whisker aspect ratio is larger; the crack deflection is more significant, which help to improve the mechanical properties of the composites.
Meanwhile, whiskers dispersed unevenly, porosity increased, the material density decreased, resulting in decreased mechanical properties [6].
