Analyzing these factors should be combined with practical condition.
So the bolt is not affected by any force. .
(3) Use appropriate thermal treatment method to improve the mechanical property of the self-adjusting bolt, and take surface strengthening measures,and improve its fatigue life.
And also take mechanical analysis to determine the most dangerous position.

Other factors affecting fatigue include high vibration due to crankshaft imbalance or lack of a counterweight, lubrication between the bearing and main journal, high pressure caused by cylinder combustion, and the appearance of cracks during the manufacturing process especially between the crankpin-web fillet areas [13].
Afterward, the mechanical properties were also ascertained.

Under the same technological conditions, it was found that the critical factors affecting the electrolyte service life are the single-processing area and the electrolyte volume.
Introduction Magnesium is the lightest of the structural metals, and has excellent physical and mechanical properties [1-2].
The study about micro-arc oxidation is focused on the influence of power supply, parameters and electrolyte on the coating performance such as the wear resistance, corrosion resistance, electrical insulation, micro hardness, and adhesion to substrate [6-8], much less on the electrolyte service life and its influencing factors in the continuous work.
In this present work the influencing factors of the electrolyte service life on AZ91D will be researched.
And the influence of these factors needs further research.

As one of main parameters that represent the mechanical properties of subgrade soil on flexible pavement mechanics - experience design method[2], the dynamic resilient modulus can better reflect the performance of subgrade soil.
The domestic and international studies have shown that the main influence factors on the dynamic resilient modulus are soil group type, humidity, degree of compaction and stress conditions[3].
Material and test method Basic physical properties of soil.Based on Test Methods of Soils for Highway Engineering [6], the basic physical properties of high liquid limit soil are listed in Table 1.
Therefore, when the prediction model of the dynamical resilient modulus is established, the relationship between stress and strain should be first established as accurately as possible, and the influence of other factors can be reflected by the model parameters.
The composite model can fully reflect the mechanical traits of material.

This result engendered a serious threat to safety of people life and property, caused devastating consequences to nearby residents, affected social harmony and stability.
Coal mine enterprises have done a lot of works on overburden subsidence and ground movement prediction, related mining damage to buildings and other issues affecting evaluation, obtained many beneficial experiences and outcomes.
As a qualitative evaluation of the movement of overlying strata in the "three zone " theory in our country is widely applied, accumulated certain experience, but according to formula (1), calculating caving height to only consider the orebody mining thickness factor, ignoring the rock properties, dip angle and other factors, which to some extent affects the accuracy of judgment.
But as a result of simulation being the ideal model of empty area, the rock mechanical properties makes its weakening due to the time effect around the ore and surrounding rock.
As time is going on, the strength of surrounding rock will reduce gradually under the influence of factors such as goaf in groundwater, geological movement in underground mining and blasting.

The strong electrnegativity of the F atoms makes the Si-F bond of a high polarity, probably affecting the complete Si-O network, and favoring the reaction with the polar H2O molecules.
Evolution of mechanical hardness with precipitate formation: Evaluation of mechanical properties of inter-layer dielectric materials is important because these coatings undergo multiple thermal cycles and CMP processes in IC fabrication.
Additionally, mechanical properties of the low-k materials have been shown to depend on their k values.
To evaluate the mechanical properties, hardness of SiOF film was measured using nanoindentation technique.
The reduction in hardness with increasing fluorine concentration indicates degradation in mechanical properties of SiOF film due to increased film porosity by fluorine incorporation.

The durability of structures is affected, but the structure will not collapse.
Fatigue damage is a fading process of the mechanical behavior of structural material.
