The performance of spindle system of machine tools directly affects the characters of machine tools.
The static and dynamic stiffness of spindle system is one of the main factors that affect the machining precision of machine tools and the performance analysis of spindle system occupies an important position in the design of machine tools.
Since the products of NC machine tools are developing toward high precision, high rigidity and high speed and the demand on the dynamics properties of spindle system is becoming high increasingly, the research on statics and dynamics properties and structure optimization for the spindle system becomes more and more important.

The paper had studied the property of corrosion resistance of AlCoCrTiNiCu_x high-entropy alloys by using the way of loss-weight.
Generally, there are a number of factors that could affect the corrosion resistance of metal material, in addition to the components of the materials, the factors of the medium in the environment, the temperature, the relative motion between the metal material and the surrounding medium and so on also have important relation[1-4].
The weight-loss method has been used to determine the corrosion resistance property of the AlCoCrTiNiCu_x high entropy alloy, Because of its simple operation, the test results are sensitive and effective, and the method is also very extensive.
The corrosion resistance mechanism of AlCoCrTiNiCu_x high entropy alloy in the mixed corrosion solution of 1 mol/L NaCl and 0.5 mol/L H2SO4 is as same as in the 1 mol/L NaCl solution and H2SO4 solution, which are all affected by the Cr, Ni, Ti and Cu elements.

The reinforcing fibre in the composite affects the main lamina properties, such as the tensile modulus and strength in the fibre direction.
Mechanical Properties of Composite Lamina.
Table 1 shows the mechanical properties of the unidirectional composite lamina employed in the FEA model.
The mechanical properties of the liner materials are given in Table 2.
The minimum factors of safety in the fibre direction is equal to 1.18 (layer 14 in Fig.3 (a)), the minimum factors of safety in the transverse direction is 1.0 (layer 3 in Fig.3 (b)) and the minimum factors of safety in the shear is about 3.0 (layer 4 in Fig.3 (c)).

There has been a growing demand to meet the severe requirements of the design engineers for fabricating thinner section castings with excellent mechanical properties [1].
Hence, one of the prime factors to be taken into account in foundry practices of thin section castings is the fluidity and a thorough knowledge about the various factors influencing it is also essential [4].
The factors determining fluidity can be basically divided into (i) metallurgical variables, such as composition, superheat, latent heat, surface tension, viscosity and mode of solidification and (ii) mold/casting variables, such as part configuration, cooling rate, degree of super heat, mold material and its surface characteristics [5].
Cr has been reported as a destructive impurity for mechanical properties of Al-Si alloys [8].
The fluidity of the melt is affected by both the morphology and volume percentage of intermetallics.

Introduction Glass waste pollution is a global environmental challenge affecting many regions of the world.
An experimental program was carried out, including fresh state properties, mechanical and durability properties.
Tests were conducted according to national (NTP) and international (ASTM) standards to analyze the physical and mechanical properties of fine and coarse aggregates.
Methodology A The experimental procedures used to evaluate the mechanical properties of pervious concrete mixtures that include residual glass powder will be detailed below.
Finally, one of the factors contributing to the increase in compression strength of concrete with RGP is the fineness of its particles and the level of replacement [10].

In fact, preliminary tensile and Nakajima tests (both at room temperature and in warm conditions) revealed that the mechanical and formability properties of the investigated alloy are strongly affected by the strain rate.
Aluminium (Al) alloys are well suited for this purpose: high mechanical properties and low density make them particularly attractive for the automotive industry [4–6].

Evaluation of formability properties.
It is worthy of notice that the temperature increase led to a strong reduction of the mechanical properties of the alloy.

Most hydraulic components used mineral oil as the pressure component cannot be used for water hydraulic application because the properties of water significantly different with mineral oil.
The density of water is higher than mineral oil and the result of those properties will be increases pressure losses and dynamics effect on control valve.
Most of system analysis based on the properties of water that will be effect in water hydraulic.
The designations were depended on the tank volume, position and pump suction pressure to reduce the effect of water properties limitation.
There are some of water properties changed affect by temperature, which is viscosity, density, and cavitation.
