Based On The CLO3D Fabric Drape Simulation Studies

the influence of fabric drapability aesthetic feeling is one of the most important factor in a number of factors,with excellent drape of fabric is easy to form good drape effect.Once upon a time people can see that in the study has become increasingly in-depth study of drape,limited to the definition of drapability and evaluation,the development direction of drape is more and more in the direction of the computer simulation of the real human body wearing status and effect of the development.But for the computer system and real fabric drape parameters of the relationship between research study very little.Could have on the basis of CLO3 D system,based on the simulation of fabric property parameters for CLO3 D independent variable,the real fabric drape indexes as the dependent variable,establish regression model,hanging by measuring the real fabric drape indexes and corresponding simulation CLO3 D are obtained in the simulation of fabric fabric properties parameters,by adjusting the simulation of fabric properties parameters,can accurately simulate the costume in the suspension effect of human body.Subject through the observation of the various parameters in CLO3 D analysis,selection of the influence of suspension form the largest eight factors,respectively,stretch,weft stretch-warp,shear,bending and weft,bending and warp,buckling thewire,buckling stiffness and density.Then select the characterization of 13 drape of fabric drape performance indicators,drape coefficient,respectively,the number of corrugated,the projection area,the average wave Angle,the Angle of the wave crest irregularity,average trough Angle,etc.To the factor analysis of 3600 set of drape indexes,extracted the fabric drape shape factor and fabric drape morphological variation factor,the two main factors of the cumulative contribution rate was 82.649%,and the comprehensive reflect the characteristics of fabric drape contains basic information,achieve the goal of the factor analysis.With real fabric between the results of the indicators of main factor analysis,principal factor analysis results show that the virtual fabric main factor analysis results are basically identical with the actual fabric.This topic selected the 60 pieces of real fabric drapability verification test,the fabric drape performance verification experiment shows that silk drape simulation effect is not very good,and then to the other 50 groups of other components of the simulation of fabric drape coefficient,the number of the corresponding real fabric drape coefficient,the number of t test,results showed that 50 organizations in 41 group drape coefficient,no significant differenceBy six kinds of fabrics made of semicircle skirt,predicts the trailer real clothing validation of regression model,according to the characters of the modelling of semicircle skirt,determines the number of positive ripple,ripple back number,lateral corrugated number,the total number of ripples,positive skirt Angle of development Angle,the side skirt show six indicators,through the six indexes,compared the real semicircle skirt in outward appearance and CLO3 D semicircle virtual fitting skirt appearance in form.According to the results in the 36 group contrast data when the communist party of China(24 groups of data,equal to the total,according to 67% of the other set of data difference is not big.Both verification test proved the validity of the trailer to predict regression equation,the prediction model can not only improve the efficiency of costume design,can also reduce the cost of new product development costs,the study both for textile industry,or for clothing and apparel CAD industry,has important practical significance.
