Engineering properties of Mengzi expansive soil Mengzi Town is located at latitude 23°20′, longitude 103°23′, with height 1309 meters.
The physical and mechanical indices of Mengzi expansive soil are listed in Table 1.
Comparing to expansive soil in other areas, Mengzi expansive soil has some bad engineering properties, such as higher moisture content, higher void ratio, lower density, higher plasticity and stronger shrinkage.
Also the water content which affects expansion deformation is more sensitive than the dry density.
The first three factors are the intrinsic factors of water immersion expansion deformation.

The transfer of heat is a key process that affects the evolution of the mechanical properties in the wax pattern and it is essential that the thermal contact conditions between the blank and tool are properly described in the forming simulations.

In recent years, studies focused on the role of vanadium in steels and affection on microstructure and mechanical properties [2-5].
Practices found vanadium content in rebar was unstable and in the range of 0.001-0.014% which leaded to fluctuate more than 40 MPa in the mechanical properties with the traditional double process.
The average manganese content decreased 0.25% and the average vanadium content increased 0.016% under the similar mechanical properties (Rel/R0=1.15, Rm/Rel=1.33).
Table 4 shows properties of HRB400E by V-iron alloying and its properties meet HRB400E requirements, the average yield strength of vanadium ball alloying was 447 MPa slightly lower than that of traditional FeV alloying which was 458MPa.
Affect factors on performance decreased were large number of impurity elements in vanadium-containing molten iron.

It was found that the holding force during the forming process deeply affects the results, and a range of values was established in which the process is assumed to give a good quality piece.
Incremental programs are computationally more intensive and require all the tooling information to be input, but they consider all the forming factors such as die geometry, blank shape, sheet thickness, blank holding force, friction and so on.

Many statistical metrics have been applied to gear damage assessment, such as the root mean square, crest factor, and kurtosis, etc [1].
Most of these metrics measure the vibration intensity or characterize the statistical properties of gear vibration signals from the viewpoint of statistics.
Usually, the dynamic system of a gearbox exhibits nonlinearity, due to the intrinsic complicated motion, time-varying running condition, and fault induced factors.
For dynamic systems, the evolution of any state variable is the result of interaction between all the affecting factors, and contains the evolutionary information of other related state variables.
From the viewpoint of complexity, when a crack appears on a gear tooth, more factors will get involved in the gearbox vibration, thus the dynamic system becomes more complicated.
