苏章仁:赋予生硬呆板的产品结构“类生态活系统”

2017-08-13 08:56:47   中国经济网

生态设计是制定产品在满足人类生产生活最佳功能的全寿命周期,以最小的熵污染、最小的资源、能源与能量消耗可实现的‘蓝图’以及产品残值出路的方案。

人类生产与生活中,作为在动静态过程承受载荷的产品结构无处不在,涉及整个工业领域,占用大量资源与能量。

人类在传统零和博弈思维下,整体结构力学性能是基于“以单件结构力学性能冗余为基础,向整体结构层层叠加”的实际思维习惯设计与制造获得。其承载能力以不变应万变的生硬、呆板的“对抗”形式构成。冗余质量造成多余的熵污染、能源与能量消耗。大量装备甚至武器装备的超重即是证明。

当代以新博弈思维,借助设计与制造精细化技术,融合结构几何形态的多元力学特性,赋予结构和材料可控与容许的“应变”能力,使结构具备类生态活系统的活力——在结构承载过程,经应变系统性再分配应力可无反馈跟踪自组织,实现即可分部自适应又可集成自适应载荷变化的随机应变能力。

无多余质量的结构,以最小的熵污染、最小的能量消耗为产品全寿命实现最佳功能提供生态保障。

这也是生态设计的灵魂。

化结构呆板生硬之腐朽为生态灵动之神奇、实现结构与材料综合力学特性面向生态的最优化组合,其工程技术实现路径是液态金属精与密的成型及未来的3D打印。

安阳强基精密制造产业园公司的成功不仅在于绿色制造也在于与生态设计互动,其震撼人们的产品减重效果,证明了赋予结构“类生态活系统”是可行的。(安阳强基精密制造产业园股份有限公司首席科学家 苏章仁)
