摘要:

为了提高在不同路况下男式骑行服上衣的动态压力舒适性,以170/88A男性中间体为研究对象,借助三维人体动作捕捉系统,捕捉人体在平地,上坡和下坡3种不同姿势下的骑行动作,获取其动态数据,导入至Motion Builder和3DSMAX软件中进行虚拟模特的建模。借助CLO 3D软件的虚拟压力测量模块,测量并分析站立和3种姿势下骑行服上衣的动、静态压力及其差值,不同骑行姿势下的压力分布情况存在差异,且不同衣片的压力情况也存在差异。在各衣片的样板优化过程中,分别基于压力显著较高的姿势下的虚拟模特进行试穿和结构优化。优化后平地,上坡和下坡姿势下骑行服上衣的压力总值分别下降了46.6%,43.7%和38.7%,压力折线趋于平缓,大部分测量点的压值显著下降,上述结果表明该方法显著提升了骑行服的服装压力舒适性。

Abstract:

To improve the dynamic pressure comfort of men's cycling jacket under different road conditions, 170/88A median men are taken as the research objects, and the riding actions of human body in three different postures: on the ground, uphill and downhill are captured, with the help of a three-dimensional human motion capture system. In order to obtain the dynamic data of different riding actions, they are imported into Motion Builder and 3DSMAX software to model virtual models. With the help of a virtual pressure measurement module of CLO 3D software, the dynamic and static pressures of the cycling jacket and their difference in standing and three postures are measured and analyzed. There are differences in the pressure distribution in different riding postures, and there are also differences in the pressure of different garment pieces. In the optimization process of the template of each garment piece, the virtual models try on in postures with a significantly high pressure and the structure is optimized. After optimization, the total pressure of the cycling jacket on the ground, uphill and downhill decrease by 46.6%, 43.7% and 38.7%, respectively. The broken line of pressure tends to be flat, and the pressure values of most measuring points fall significantly. The above results show that the proposed method significantly improves the pressure comfort of the cycling jacket.

Key words: cycling jacket, motion capture, virtual pressure measurement, template optimization, pressure comfort
