blank shape

Inverse Approach has been selected to calculate the blank shape and independent finite element program has been developed.

合理地选择冲压件的毛料外形 ,可以提高板料的可成形性 ,同时也可以提高材料利用率。

The effectiveness and accuracy of the inverse approach method in blank design are validated by a typical example of a cone-shaped basin.

以锥形盆为例,验证了根据有限元逆算法设计的毛料展开程序在毛料展开中的有效性和精确性。

This paper discusses the effects on the shrinkage of wool fabric through drying experiment of wool fabric.

　通过对毛料织物进行干燥实验,对毛料收缩率的影响因素进行了探讨,实验结果表明:毛料收缩率主要受干燥时传输速度、环境温度、环境湿度的影响。

basic mechanics parameters of 43 kinds of worsted fabric gathered in domestic factory are measured with KES FB instrument, then silhouette and hand of those fabrics are evaluated with the evaluation methods of mens suit fabric that developed in 1970s and the evaluation methods of womens suit fabric that developed in 1990s.

采集 43种国产精纺毛料 ,用KESFB风格仪测试出试样的 16项基本力学指标 ,用日本 2 0世纪 70年代开发的男士西服面料和 90年代开发的女士服装面料的风格评价方法评价面料的成形性和手感性能 ,发现目前的国产精纺面料仍然主要适合制服类服装 ,很难找到适合悬垂类和宽松挺括类服装的精纺毛料。

Combining with continuous process the technology of producing aluminium foil stock with two high mill cast rolles were introduced.

结合生产实际，介绍了用双辊式连续铸轧机生产铝箔毛料的工艺方法。
