The vibration reduction of a coach with the suspension system is achieved by controlling the stiffness of the air spring and the damping of a switchable damper.
Relative damping ratiocan be used to evaluate the degree of vibration reduction.
According to the above simulation data in graphs, it is found that the seat vertical acceleration RMS reduced by 23.2% which gives a large improvement in ride performance; in addition, the RMS of the suspension dynamic deflection and the tire dynamic load have a little increase but still in the constraint condition.
The simulation data was analyzed.

Quantities of billets were compressed at constant strain rate and temperature with 60% height reduction on Gleeble-3800 thermal simulation testing machine to study the plastic flow behaviors of the test alloy.
Therefore, based on the experimentally measured data, a number of research groups have made efforts to develop constitutive equations to describe the hot deformation behaviors of metals and alloys.
The samples were deformed up to 60% height reduction.
Utilizing the experimental data, the plots that describe the relationship between peak stress and strain rate according to the power law and exponential law are given in Fig.6.

Practically, the data of input-output table is at sector-level, furthermore, it includes both direct and indirect influences of sectors.
The SDA model and data preparation Construct the SDA model.
Data.
China’s IO tables of 1987, 1990, 1992, 1995, 1997, 2002, 2005, 2007 and 2010 are merged into 26 sectors, so that it is consistent with the energy data.
Since the IO tables of 1987, 1990, 1992 and 1995 only have “net export”, we use the import and export data at sector level of [6].

The data shows that with increasing illumination intensity, the C-V curve shifts toward a more negative bias.
The G-V data shows a reduction in amplitude of the main peak with increasing illumination intensity.
This is similar to that observed in the λ=350nm data, and is thought to be related to the changes in time constant of the dominant trapping state [7].
The data also shows that the second peak increases in amplitude with increasing photon intensity.
The data indicates that following illumination at both wavelengths, the electronic distribution within the interface changes.

In this work, the wool keratin solution was obtained by a reduction method, and mixed with sodium carboxymethyl cellulose (CMC) solution in order to prepare blend membranes.
In this paper, a reduction method was adopted to dissolve wool and prepare keratin solution as reported previously.
The thickness of membranes was measured by an electronic digital micrometer; each sample was tested five times at different positions, and the average of the data was used.

A 42%-increase of the maximum peak-to-peak value of the echo pulse response, a 52%-reduction of the ring down time and a 200%-increase of the bandwidth can be achieved by using the backing material.
In order to improve the accuracy of data processing and effectiveness of the structural health monitoring, the increase of the sensitivity and resolution of the sensor are desired through a reasonable selection of backing material that matches well with the piezoelectric element [4].
The time domain response and frequency spectrum of CPUS, tungsten power/epoxy resin backing layer From the time domain responses in Figs. 2~5, it can be seen that, under resonant frequency excitation, no distortion of the received waveform, significant increase of the first pulse amplitude and peak-to-peak value, as well as a reduction of the pulse shock time are shown when metal powder/epoxy resin composite materials backing layers are used.

Increasing the temperature of thermal stabilization, as well as the tensile load onto the bundle causes a significant reduction in the time during which the process of dispersion of precursor material develops and formation of a new high dispersion phase of thermostabilized fiber.
The length reduction is 9% at the same temperature of isothermal stabilization.
These data suggest that the formation of the structure of thermostabilized PAN fiber proceeds via the formation of a new fine phase (average size ~1 nm) in local microvolumes - CSD3.

This paper provides a valuable reference for the vibration source identification and structural vibration reduction.
Firstly the power spectrum density functions are obtained by calculating the data in time domain.
This paper provides a valuable reference for the vibration source identification and structural vibration reduction.

Test results show that with micro-channel size decrease, the percentage reduction in viscosity increases and the difference of viscosities in different micro channels reduces with increasing shear rate.
For Non-Newtonian fluids, two corrections are commonly applied to capillary data to obtain the correct viscosity of polymeric fluids.
For different materials, the reduction of viscosity at the same shear rate is various, which shows that the variation of viscosity has relationship with polymer melt category.

It was shown that reduction of carbon and oxygen components from the surface contaminants as well as the existence of a nonstoichiometric SiOx layer on the Si surface contributed to the hydrophilicity of the substrate.
Si2p peak fitting data show that plasma exposure reduces the concentration of Si-O bonds, representing nonstoichiometric (SiOx) in natural silicon oxide on the silicon surface.
Reduction of surface contaminants containing carbon and oxygen components as well as existence of the nonstoichiometric SiOx layer on the top of the Si surface contribute to the hydrophilicity of the substrate.
