With widely using difficult-to-process materials, such as the stainless steel and SnSb alloy, the magnetic-electrochemical compound polishing process has been paid much more attention by some Japanese and Chinese researchers.
Introduction Compound polishing methods are now being studied and applied in processing parts of materials that are difficult-to-process[1].
Fig.1 The charged particle in electromagnetic field Especially, some researchers have put forward the magnetic-electrochemical compound polishing process to difficult-to-process materials parts such as stainless steel, SnSb alloy.

First introduced the horizontal extension of the overall structure of the supporting of coal mine belt which leads to support the working environment of the vehicles, then comparison of traditional materials and new materials to support the vehicle body, trying to replace traditional materials with new materials, and new materials for static mechanics and fatigue analysis, we found the support body after the application of new materials fatigue life less than ideal requirements, and thus try to use new materials to support the car body laser coating technology to improve, after ANSYS fatigue test, and validation support guide the application of coating on the car body can effectively improve the fatigue strength, has good application prospects.
Analysis the Supporting vehicle’s Materials.
Analysis of the two materials fatigue calculations.
New materials, coating and fatigue check.

Recently, the demand to produce lighter weight, yet safer vehicles has led to the need to understand the crash behaviour of novel materials, such as fibre reinforced polymer composites, metallic foams and sandwich structures.
Recent demands to reduce fuel emissions without sacrificing the safety of the vehicle structure has led researchers and automakers worldwide to study novel light weight materials such as composites, metallic foams, sandwich structures etc.
Tubes are used to characterize the energy absorption of different materials as they closely represent the automotive crash rails.

Then the oversize (dry material A) and the dry cake (dry material B) can easily be transported to the stock pile.
Once the worked out section has formed, the dry tailings material can be moved to there by carry-scrapers directly.
