Rockfall impact signal and noise clearing Rockfall impact signal is shown in Figure1,2.Because of interference from external and internal equipment, there will produce some useless noise mixed with the signal in the acquisition.Therefore,in order to make the test data more reliable, the collected signal must clear the noise, in this article,we use the wavelets theory to clear the noise from the test data.
The basic principle of wavelet noise clearing is:length N of the signal is disturbed by the noise, the measured data with noise is ; therefore the fundamental purpose of filtering noise from the noisy data X is to get an approximate signal from the signal, makes is optimal approximation under certain error estimates, that is to get the real signal.Signal without noise is shown in Figure 4, Ratio of signal and noise can be used to evaluate the wavelet noise clearing.
Ratio of signal and noise is a traditional method of measure the amount of noise, often used as evaluation index of the effect of noise reduction ,units is decibel(dB) ,and is defined as follows: (1) (2) Among them, is the power of true signal; is the power of noise; is the original signal; is the estimate signal after the wavelet noise reduction.
Ratio of signal and noise after the noise reduction is larger,the effect is better .
Since the true size of the signal is unknown in this article, we can only use the original signal to estimate the parameter of noise reduction.

Numerical sintering studies were supplemented with experimental studies that provided data for calibration and model validation.
The heat resistance of NiAl-based alloys can be increased by alloying or by creating special nanostructures in the alloy — directionally crystallized or non-directionally crystallized, thus providing a reduction in the proportion of transverse boundaries.
At the first stage of experimental studies, differential thermal analysis (DTA) of the process of reduction of neodymium from a technological salt mixture with a magnesium-zinc alloy was carried out.
Experimental data can be used to simulate the sintering process of powder material Contact and Sintering Behavior To calculate a large number of particles, and in particular for sintering processes, the discrete element method is used.

The EBFF work indicated that build-ups with either filler material could be deposited on 321 SS using an optimized processing window that resulted in properties comparable to technical data available for 347 SS and BNi-2.
However, a greater reduction is observed for the application of three re-melts where only a build-up rate of 350 µm per layer was obtained.
With multiple-melt processing, the reduction of the growth rate in the height of the build-up is associated with an increase in the deposit width, which caused a reduction in height to width ratio from 1.5 to 0.85.
For 347 stainless steel (AMS 5512), the material data for sheet, plate or bar stock indicate values of 167 HV for an annealed microstructure [8], while 347 type welding wire feed has been reported to have hardness values of 150 to 210 HV [9,10] and an as-welded hardness of 169 HV [11].
Hence, the hardness values obtained in the present work for the six-layer build-ups correspond closely with the reported data for grade 347 SS in general.

The elastic and plastic parameters, which determine the curve in elastic and strain hardening stages, were obtained from the experimental data.
Fig. 4 Crack length versus reduction for different tension A comparison of the crack length of simulated and experimental results is shown in Fig. 3.
It is shown that the crack length increases with the increasing of total reduction.
The variation of crack length versus total reduction for different tension level is shown in Fig. 4.
The two results agree well with each other and indicate that crack length increases with an increasing of total reduction and unit tension.

So in the course of change steel grade St.3sp to steel grade 40, this reduction is equaled to 0.2 m/min, and for steel 85 is 0.4-0.5 m/min, depending on the billet cross sectional area.

An array of 96 melting data was investigate to clarify this effect.
The presented data indicate, that the sulfur content in the considered range did not have a significant effect on the withdrawal speed of the billets.

Again, the curve of elasticity modulus is fitted in the light of the experimental data, which can reveal how the elasticity modulus changes with plastic deformation.
It was concluded that the non-uniformity of yield stress can greatly impact the reduction of residual stresses.
The test data can be accurately expressed by
The parameters, including the yield strength, elastic strain of post-quenching, equivalent plastic strain of quenching, elastic modulus and shear modulus after quenching, can be achieved by substituting the data in Table 1 and Fig. 1 into Eqs. (1-7).
The comparison of the improved simulations with experimental data [7] is shown in Table 2, as well as of the unimproved simulations with experimental data.
