Its performance is an important factor affecting the vehicle braking performance, so the design and test of the regulator is very strict.
The Mathematical model of pneumatic ABS pressure regulator The performance of regulator is affected by some parts, including mechanical properties, fluid properties.
According to these properties, the mathematical model is built.
These components can be found in the library of mechanical, pneumatic, pneumatic component design, signal and control in AMESim.

The experiments are conducted using one-factor-at-a-time approach.
Titanium and its alloys are considered excellent materials for their applications in aerospace and automobile industries because of their improved mechanical and physical properties like high strength, high strength to weight ratio, high toughness, corrosion resistance and oxidation resistance.
However these properties also make titanium and its alloys difficult to shape and machine into a precise shape and size.
The effect of this factor appears to very weak as compared to effect of TON and TOFF.

Introduction As is known to all, the chatter in the high-speed grinding is one of the important factors affecting the surface quality of the grinding.
Through analysis of the generative mechanism and effective factors of the regenerative chatter, the dynamical model of the regenerative chatters of the workpiece and grinding wheel during the cylindrical grinding should be established and solved.
So vibration properties of the grinder can be measured by vibration energy.
(2) The dynamical property of the grinding process is influenced by the variation of the grinding parameters.

The SLM process is influenced by a large number of factors related to the using materials and to the laser melting process: temperature, gravity and capillary effects, while there is no mechanical pressure during the manufacturing processes.
The information about the influence of factors on the final density of the material is presented at [8].
Despite the advantages of additive technologies, there are various defects that can be harmful to the mechanical properties of products.

In order to understand the factors that affect the mechanical strength, effect of precursor solubility was studied on the mechanical strength of the hydroxyapatite (HAp) block using two different precursor blocks, αTCP and beta-tricalcium phosphate (bTCP), which were chosen since they have the same chemical composition but with different solubility [5].
The result implied that mechanical property of CO3Ap foam would be improved using bTCP form precursor instead of αTCP form.
The mechanical property was compared to CO3Ap form prepared from αTCP form to identify whether the mechanical property could be improved or not.

Analysis and Planning of the Experiments Cutting feed f, cutting depth ap and cutting speed v were three turning element factors, so they were selected as the experimental factors in the Taguchi's L27(3 13) design of experiments; burnishing feed fb, burnishing depth ab and burnishing speed vb were the most important factors in determining burnished surface integrity, so they were selected too.
The key problem was which three factors should be selected as three interactions between with.
Fig.6 shows that the increase in f increases the burnished surface roughness, because the initial idealized surface roughness Rai before burnishing is determined by the surface irregularities and f is the only cutting parameters except the cutting tool properties that determine surface irregularities.
Fig.9 Response graph of microhardness vs. f Fig.10 Response graph of microhardness vs. fb Fig.11 Response graph of microhardness vs. vb Conclusions f is the only significant one among all 9 factors in determining burnished surface roughness, because compared to the critical influence on initial surface roughness, other factors' influence can be neglected and submerge into experimental noise.
The factors related to f including f, ab×f and f×fb all have significant (or highly significant) influence on surface microhardness.

The brittle property of IMCs caused the strong stress concentration effect during the mechanical impacts [2,4-15] and thermal cycles [1,3] The cracks were found to initiate and propagate near the IMC layers.
Past studies in the solder joint failure Many factors are affecting the fracture toughness of solder joint, such as solder joint thickness and crack location related to interface of solder joint.
Alam et al. [4] has showed that the stress intensity factors (SIF: KI and KII) increases with the thickness of solder alloys at the loading rate of 0.8 MPa/s for the crack located at 1μm distance apart from the IMC-solder interface.
Specifically, factors which include package size, solder type, model type, experimental parameters (ATC), computer simulations (mesh size) affect the results.
Conclusion Many studies have been carried out on the effect of fracture factors on solder joint failure like solder thickness, IMC thickness, crack location, crack length, electric current density, strain or loading rate and temperature cycle.
