According to three dimension braided composites for braided technology - four - step and technology - two - step procedure , and with reference to theories of braided fabric geometry and force models , a geometric model is built . in this model , the cross - section of thread is described as a circle and thread path as a cubic b - spline . braided - fabric structures in three dimensions are displayed by using solid - modeling techniques 本文三維編織物根據(jù)四步法和二步法編織工藝,從紗線的力學(xué)模型出發(fā),建立了以圓形近似描述紗線的截面形態(tài),以三次b樣條曲線近似描述紗線的屈曲形態(tài)的織物空間幾何模型,利用計(jì)算機(jī)三維實(shí)體造型技術(shù),分別建立各自的編織物實(shí)體模型,用來模擬織物內(nèi)部各紗線的空間位置,完成織物結(jié)構(gòu)仿真。
