Performance of on-site assembly is simple and reliable ,convenient transportation, separation.So it is widely used in mining, metallurgy, building, materials, railway and other industries [1-4].
From the waveform of vibration can be seen in Figure 5:(1) With the start of crusher, The vibration signal of the eccentric shaft bearing seat began changing and until after completion of starting stage into stable no-load operation;(2) Vibration which crusher broken material is the most intense vibration;(3) Vibration amplitude corresponding to frequency of loading conditions is larger than no-load condition,so it is in line with the actual conditions of crusher.

Relevant Technical Requirements Analysis of Related Raw Material in Coarse Aggregate Concrete By summarizing the relevant literature, combined with practical experience summary of the author, in raw materials’ technical requirements in concrete, basically, not only should common concrete be in line with raw materials technical requirements, the effect of varieties of fine aggregate and coarse aggregate on cement dosage should also be fully considered.
Aggregate can be used as cheaper filler material comparing to cement slurry in project, and the new building material’s cost is cut down.

Reconstruction Analysis of LH45 Type High Pressure Triplex Plunger Pump Shell Chang Wang, Jingjing Gao Mechanical Engineering School of Inner Mongolia University of Science & Technology, Baotou, China wangchang888@sina.com Keywords: Plunger pump; Shell; FEM; Reconstruction.
Studied the pump housing broken state and laws to selected material to manufacture.
According to the attribute table defined material properties, properties are shown in table 1.
The maximum stress value is far less than the yield limit of material 540MPa and the tensile strength values [σ]=735MPa.
Conclusions (1) Through different materials of high pressure triplex plunger pump shell before and after reconstruction of the finite element analysis shows that the transformation before and after the shell of the strength and stiffness are all meet the requirements, but after the transformation of the shell is more safe and reliable than the transformation before.It will be more correctness and feasibility

The appeal of RPFEA method stems from its ability of being easily implemented in the form of computer programs that can systematically represent material behavior and complex boundary conditions [3-4].

In the acceleration process, vibration equation can be expressed with variables of time and displacement as Eq. 1: (1) Where, m1 is the weight of the drill string from the jar to surface, E is the elastic modulus of the material, β is the damping coefficient, L1is the length of the drill string from the jar to surface, A1 is the equivalent cross-sectional area of the upper part of drill string as Eq. 2: (2) Linear damping is a commonly used damping model.
According to mechanics of materials, the natural frequency can be expressed through the equations as Eq. 6: (6) The natural frequency and damping vibration frequency can be calculated with the elastic stiffness of the drill string by Eq. 6.
