The paper studies the vibration transmitted by a mechanical oscillating system to its fixing device.
However, the real constraints are made by means of bodies which are also elastic, so that the studied system (the principal sub-system) is part of a system with supplementary degrees of freedom, whose vibratory behavior is affected by the mechanical characteristics of the fixing device (fixing sub-system).
At the same time, the studied mechanical system transmits vibrations to the fixing device.
The ratio , plotted in Figure 7, tends to become constant for perturbation frequencies lower than 30 Hz, which validates the property found in the previous paragraph.

SWCNTs are very important type of CNTs, because their properties vary significantly with chiral vectors.
The band gap of SWCNTs can vary from 0 to 2eV, thus electrical properties can be metallic as well as semiconducting.
Electronic properties of GNR vary with the edge pattern as well as the width of the sheet.

Introduction Double-tower connecting structure is a kind of complicated structure form with two single-tower as major structure which are connected by linkwork(corridor, for example).This kind of structure has great calculation workload, complex stress, and many influential factors.
Compared with ordinary high-rise buildings, the vibration performance, mechanical property, failure mode and analytical model of double-tower connecting structure are much more complicated.
In this paper, an unequal altitude double-tower connecting structure is taken as an example, whose dynamic property and seismic response are analyzed using the finite element analysis software, ANSYS, and some reasonable advice are put forward for architectural design.
The statements of above illustrate that the shear force on the bottom is affected significantly by connecting position.
(3) The variation of connecting position mainly affects the stiffness in X direction, therefore, after inputting earthquake wave in X direction, the maximum shear force on the bottom varies significantly.

Inside these ceramic coatings, the mullite is a good option, since it presents very good mechanical properties, great corrosion resistance, high thermal resistance and high durability.
Meanwhile, FGM concepts have triggered world-wide research activities and are applied to metals, ceramics and organic composites to generate improved components with superior physical properties [3].
In this case, the different deposition times affect the film aspect.
The dissimilar amount of species is important for the 30 min. and 60 min deposition times because the film properties and characteristics change with this variable.
But these results must be confirmed experimentally since kinetic factors exist and these determine the final result of the oxide process. 300µm 500µm 100 µm 40 µm (a) (b) The first oxidation conditions indicate that the best results were obtained at higher temperatures.

The size of the collector droplet is an important parameter that affects the performance of the equipment.
According to studies by Guerra et al. [7, 8], such factors influence the droplet size significantly.
This is a useful technique in all experimental areas of engineering because if it is possible to identify the relevant factors involved in a physical process, a dimensional analysis may form and reveal a relationship between the factors.
Results and Discussion To apply dimensional analysis to a process, the relevant physical factors that influence a process must first be established.

On the basis of analyzing the properties of the Camellia oleifera peel and seed, for the purpose of solving the problem of the separation of peel and seed, a device has been designed based on the aerodynamic principles.
Way of rubbing roller by squeezing the fruit can achieve the mechanical shelling of camellia ,however,if want to further processing,the pericarp and seed mixtures of camellia after mechanical shelling must be separated.
Theoretical Analysis In order to have a better guidance on the production and to find out the factors that can possiblely affect the separation, the theoretical analysis of air separation on the material after shelling of Camellia oleifera should be carried out.Air separation is to use of the different of aerodynamic characteristics of materials to separate, extractions in the field of indoor air cleaning as free individuals rather than groups in the form of movement, Therefore, the movement and dynamic of extractions were analyzed,The extractions of the individual was as a point of mass m.
Test index and influencing factors.

But the mechanical aspect is specific in LCF and in GCF.
The initiation of fatigue cracks can be considered differently from physical or mechanical points of view.
According to our own observations and those in the literature two main factors are operating in the Gigacycle regime: - The stress concentration due to metallurgical microstructure misfit becomes an important parameter when the applied load is low.
It is found that gigacycle fatigue property is significantly influenced by cooling condition (ΔT in the range 12 to 65 °C).
