Siddiqui [1] analyzed the vibration property of axially moving cantilever based on flexible multibody dynamics.
So we study its vibration property from three aspects, in which consider the first three order modes
But due to its frequency equal to the natural frequency, so the second order vibration and the third order are affected to a certain extent.
So we can know the result ,which the beam is lack of vibration in curve oa, is affected by the load vector .
Although this paper provides a new theoretical way for engineering application about the axial movement of the beam under the moving mass, further analysis should be done by numerical method or experimental method, on which how other factors (e.g. initial disturbance, external load, et,al) influence the beam’s vibration in practical engineering.

The fatigue life is 50 cycles at working pressure, and the minimum performance factor is 30km.
The mechanical behavior of titanium liner is considered to be isotropic and elastic-plastic.
Each filament wound layer had its own fiber direction as illustrated in Fig. 6 and this direction information was used to determine the material properties of the composite.
This data represents a burst factor of 2.32 to 1.
The performance factor is 35.19km.

Besides the nature of constituent material properties, the microstructure of fillers
also plays an important role in the mechanical properties of the filled rubbers.
It has been known that the CB network is responsible for the DC (direct current) conductivity [1,2] and the unique mechanical behavior, i.e., the strain amplitude dependence of the dynamic viscoelastic properties [3].
Many investigators [1,4,5,6] studied the relation between the characteristics of CB network and the physical properties of filled rubber for fully understanding of the reinforcing mechanism and for the potential applications in developing a new kind of mechanical-electrical sensor [5].
This electrical property might be suitable for application to characterize the CB network and to obtain useful information about the structure and properties of CB networks in rubbers.
Besides the specific surface, CDBP, average number of primary particles per aggregate and CB aggregate distribution, other factors, e.g., the CB-polymer interaction, the surface activity of CB aggregate and the shape factor of CB aggregate which is generally defined by the ratio of the maximum dimension to the diameter of the equivalent sphere, affect the electrical resistance of CB composites.

The mechanical properties of the annealed sample are summarized in Table 1.
Table 1: Mechanical properties of a rolled Mg alloy sheet used in the present study.
It is needless to say that factors other than twinning and detwinning, such as slip activity and texture, should also affect in the deformation upon two-step loading.
Moreover, not only detwinning but also other factors including the initial anisotropy and texture should affect the r-values after the second loading.

remarkably crucial research focus in the world [1, 2].
Such properties can be utilized in the polishing of diamonds.
Simulation of Lapping Process based on A�SYS/LS_DY�A Temperature is an important factor in accelerant lapping technology.
But in fact, the metal temperature in front the tools is indeed the highest, and just being deleted, this does not affect the analysis.

Abstract.
Introduction The quality stability of airport pavement concrete is a pretty important factor to guaranteeing the safe fall of aircraft.
Since the performance of structure is largely affected by the raw material properties and mix design, so the reasonable choice is particularly important.
According to the analysis above mentioned, the 5~31.5 mm coarse aggregate will be applied to the mix design of airport pavement concrete in this paper, studying the mechanical property and frost resistance durability of airport pavement concrete using the 5~31.5 mm coarse aggregate, further providing a certain basis to optimize the specification of airport pavement concrete.
The reason of airport pavement concrete using 5~31.5 mm coarse aggregate being good mechanical property and durability is that the coarse aggregate grading has an appropriate maximum particle size and size distribution.

We have previously [1] experimentally determined the mechanical properties of the apple and the pear.
The results showed that both properties varied clearly along the axis as well as radially.
Nevertheless most authors have modeled the fruits as spherical in shape and uniform in their mechanical properties which doesn’t mimic the interior or exterior geometry of each fruit.
The former is related to the interpretation of the intensity levels in each tomogram, which should be consistent across all tomograms in a set; lighting conditions and other imaging factors should be kept constant throughout the digitization of all slices.
