服装CAD系统的自适应排料方法研究与设计

在服装制造过程中,衣片的排料结果直接影响耗材的多少,因此提高排料率是企业降低成本,提高竞争的一种重要手段。为了提高排料的效率及排料率,文章设计了一种服装CAD系统的自适应排料方法。解决了其中衣片旋转、移动、衣片重叠的判断、自动靠拢等问题,提高了排料的效率。

浅析服装成衣工艺——排料

服装成衣工艺中排料是一项技术性很强的工作,工业排料裁剪,事先由技术部门精打细算,做好各档规格的样板,然后进行排料,都是根据大小样板,批量及规格进行紧密排料,不管铺料多少层,都按一个划版进行裁剪,其特点是排料紧密、层数多、用料省、效率高。

Development of an Evaluation Methodology for Fuel Discharge in Core Disruptive Accidents of Sodium-Cooled Fast Reactors

The purpose of the present study is to develop a methodology to evaluate fuel discharge through the CRGT （control-rod guide tube） during CDAs （core-disruptive accidents） of SFRs （sodium-cooled fast reactors）, since fuel discharge will decrease the core reactivity and CRGTs have a potential to provide an effective discharge path. Fuel discharge contains multi-component fluid dynamics with phase changes, and, in the present study, the SFR safety analysis code SIMMER （Sn, implicit, multifield, multicomponent, Eulerian recriticality） was utilized as a technical basis. First, dominant phenomena affecting fuel discharge through the CRGT are identified based on parametric calculations by the SIMMER code. Next, validations on the code models closely relating to these phenomena were carried out based on experimental data. It was shown that the SIMMER code with some model modifications could reproduce the experimental results appropriately. Through the present study, the evaluation methodology for the molten-fuel discharge through the CRGT was successfully developed.
