In the process of Preprocessor, material properties such as Poisson ratio, density and so on must be defined according to reality, the next step is to mesh the objective with suitable mesh method which makes the objective ready for FEM analysis.
To be noted that the material of Slider is different from that of guide screws shown in Fig. 1.
So in preprocessor, material properties should be specified according to reality.

Use of textile friction to mimic Hill’s model in dynamic contraction of braided artificial muscles Bertrand Tondu Institut National de Sciences Appliquées, 135 Avenue de Rangueil and LAAS-CNRS, Avenue du Colonel Roche, 31077 Toulouse, France Bertrand.Tondu@insa-toulouse.fr Keywords: Artificial muscle, McKibben muscle, Hill’s curve Abstract.
This assumption is coherent with Equ. (4) derived from Hill’s model; it can however be questionable depending on used materials.

parameters’ value within the parameter’s scope and taking face milling simulation experiments for a same analysis object respectively, then many sets of data, which express the relationship between the distortion errors and corresponding given cutting parameters, will be obtained; ②The train sample data is formed using the standardized data, where is the sequence simulation number;is the multidimensional input vectors, including spindle speed, feed per tooth and axial depth of cut.is the output parameter, denoting the distortion error of simulation; ③Taking the train sample data as the original input data of the LS-SVM, the optimum parameters vector will be get by using PSO algorithm. ④Giving the optimum parametersto the LS-SVM model, then the LS-SVM regression parameters will be get by training the LS-SVM using the sample data. 3 Multi-objective Optimization Based on GRA-PSO Algorithm In order to get the optimum cutting parameters, which can achieve the higher producitivity(express by material

Statistical/ Empirical-based Vulnerability Assessment The main methodologies used in practice, based on statistical/empirical approaches are [2- 5]: · Screening and vulnerability index methods: They consist in gathering quantitative information on a building or stock of buildings, by using vulnerability-assessment forms including predetermined set of parameters, such as quality of materials.
The unmeasurable factors are the type of the nonlinear behavior (geometric or material) and the severity of the nonlinear behavior.

Cyclicity stacking patterns of Putaohua oil layer is influenced obviously by the proximity of the material source and the structural location.North of the study area is near the material source,sediment supply adequately,accommodation space relatively small,channel microfacies development,scour occur more.Lake direction away from the material source,sediment supply less,accommodation space increase gradually,mouth bar and sheet sand facies development,vertical aggradation occur more.
