The embodiment of a kind of fitted pants plate profile structure calculation method of parameters of the present invention is as follows:
Embodiment 1, slacks pattern:
1, slacks postmedial line inclination alpha is set up with the crotch buttocks coefficient of dynamics K functional relation changed
As it is shown in figure 5, set up with total crotch width x for abscissa, postmedial line inclination alpha is the coordinate system of vertical coordinate.The schematic diagram at total crotch loose of visual standard zoarium slacks and standard zoarium skirt trousers and postmedial line inclination angle from Fig. 3 and Fig. 4.According to the panty configuration principle of compositionality on clothing human body engineering basis, the thickness at gluteal fold place when total crotch width of standard zoarium panty configuration is human body clean hip circumference, now crotch buttocks coefficient of dynamics K=0.16, i.e. total crotch width x=K H=0.16H, postmedial line inclination alpha=8 ° of this moulding corresponding, reflection is in the coordinate system of Fig. 5, then the coordinate points of standard zoarium panty configuration is P (0.16H, 8)；Total crotch width of standard zoarium female's divided skirt structure is human body hip circumference place thickness, it it is the wide maximum of slacks crotch, now crotch buttocks coefficient of dynamics K=0.2, i.e. total crotch width maximum x=K H=0.2H, postmedial line inclination alpha=0 ° of this moulding corresponding, reflection is in the coordinate system of Fig. 5, then the coordinate points of standard zoarium skirt trousers is Q (0.2H, 0).Connect Q, P, then the compatibility region of total crotch width x of the corresponding total crotch width wide crotch class slacks between 0.16H-0.2H of straight line QP and postmedial line inclination alpha, these type of slacks K ∈ (0.16,0.20).Extending the limit moulding coordinate points that QP to T, T point is narrow crotch class trousers, its abscissa is total crotch width minima, and vertical coordinate is postmedial line inclination angle maximum.According to China's standard female's convex feature of body buttocks, as the postmedial line inclination alpha > 14 ° of narrow crotch class trousers, slacks pattern there will be after in buttocks pin down front and back center line to the Clothing Pressure of the human body phenomenon running counter to organization of human body such as excessive with more than lower convexity, buttocks tight, thigh, therefore postmedial line inclination angle maximum is 14 °, trying to achieve the wide minima of total crotch by graphing method is x=0.13H, now K=0.13, then T point coordinates is T (0.13H, 14).So the compatibility region of total crotch width x of the corresponding total crotch width narrow crotch class slacks between 0.13H-0.16H of straight line PT and postmedial line inclination alpha, these type of slacks K ∈ (0.13,0.16).Therefore, for all slacks moulding, crotch buttocks coefficient of dynamics K ∈ (0.13,0.20).α=40-200x/H can be obtained at 2 by P, Q.Because of total crotch width x=KH, substitution above formula obtains slacks postmedial line inclination alpha and with the crotch buttocks coefficient of dynamics K functional relation changed is: α=40-200K, wherein K ∈ (0.13,0.20).
2, slacks in-leg angle of inclination beta is set up with the crotch buttocks coefficient of dynamics K functional relation changed
As shown in Figure 6, setting up with total crotch width x for abscissa, in-leg angle of inclination beta is the coordinate system of vertical coordinate.The crotch buttocks coefficient of dynamics K=0.16 of standard zoarium panty configuration, i.e. total crotch width x=K H=0.16H, in-leg angle of inclination beta=38 ° of this moulding corresponding, reflection is in the coordinate system of Fig. 6, then the coordinate points of standard zoarium panty configuration is E (0.16H, 38)；The crotch buttocks coefficient of dynamics K=0.2 of standard zoarium female's divided skirt structure, i.e. total crotch width x=K H=0.2H, in-leg angle of inclination beta=0 ° of this moulding corresponding, reflection is in the coordinate system of Fig. 6, then the coordinate points of fit skirt trousers is F (0.2H, 0).Connect F, E, then the compatibility region of total crotch width x of the corresponding total crotch width wide crotch class slacks between 0.16H-0.2H of straight line FE and in-leg angle of inclination beta, these type of slacks K ∈ (0.16,0.20).Extend FE to G, G point represents the limit moulding coordinate points of narrow crotch class trousers, its abscissa is total crotch width minima, vertical coordinate is in-leg inclination angle maximum, and maximum total crotch loose minima corresponding when being 14 ° in narrow crotch class trousers postmedial line inclination angle is 0.13H, now K=0.13, trying to achieve G point coordinates by graphing method is G (0.13H, 66.5 °).The then compatibility region of total crotch width x of the corresponding total crotch width narrow crotch class slacks between 0.13H-0.16H of straight line E and in-leg angle of inclination beta, these type of slacks K ∈ (0.13,0.16).Therefore for the panty configuration of all moulding, crotch buttocks coefficient of dynamics K ∈ (0.13,0.20).According to E, F two point coordinates value, obtain β=190-950x/H.Because of total crotch width x=KH, substitution above formula obtains slacks in-leg angle of inclination beta and with the crotch buttocks coefficient of dynamics K functional relation changed is: β=190-950K, wherein K ∈ (0.13,0.20).
3, slacks hind wing amount h is set up with the crotch buttocks coefficient of dynamics K functional relation changed
Such as Fig. 7, foundation is with total crotch width x for abscissa, and hind wing amount h is the coordinate system of vertical coordinate.The crotch buttocks coefficient of dynamics K=0.16 of suitable trousers panty configuration, i.e. total crotch width x=K H=0.16H, hind wing amount h=H/48 during this moulding corresponding, reflection is in the coordinate system of Fig. 7, then the coordinate points of standard zoarium slacks is M (0.16H, H/48)；The crotch buttocks coefficient of dynamics K=0.2 of standard zoarium female's divided skirt structure, i.e. total crotch width x=K H=0.2H, the hind wing amount h=-H/48 of this moulding corresponding, reflection is in the coordinate system of Fig. 7, then the coordinate points of fit divided skirt is N (0.2H ,-H/48).Connect N, M, then the compatibility region of total crotch width x and hind wing amount h of the corresponding total crotch width wide crotch class slacks between 0.16H-0.2H of straight line NM, these type of slacks K ∈ (0.16,0.20).Extend NM to U, U point represents the limit moulding coordinate points of narrow crotch class trousers, its abscissa is total crotch width minima, vertical coordinate is hind wing amount maximum, and maximum total crotch loose minima corresponding when being 14 ° in narrow crotch class trousers postmedial line inclination angle is 0.13H, now KU=0.13, trying to achieve U point coordinates by graphing method is U (0.13H, 5H/96).The then compatibility region of total crotch width x and hind wing amount h of the corresponding total crotch width narrow crotch class slacks between 0.13H-0.16H of straight line MU, these type of slacks K ∈ (0.13,0.16).Therefore for the panty configuration of all moulding, crotch buttocks coefficient of dynamics K ∈ (0.13,0.20).According to M, N two point coordinates value, obtain h=3H/16-25x/24.Because of total crotch width x=KH, substitution above formula obtains slacks hind wing amount h and with the crotch buttocks coefficient of dynamics K functional relation changed is: h=3H/16 25KH/24, wherein K ∈ (0.13,0.20).
