新能源汽车铁芯冲裁粘压一体化成形工艺

设计了新能源汽车电机铁芯模内冲裁粘压一体化的制造工艺,条料在上、下模之间连续向前输送,冲裁工位包括转子铁芯的第一槽体冲裁和第二槽体和轴孔冲裁、转子铁芯用粘接剂喷涂工位、转子铁芯落料工位、定子铁芯的槽形冲裁工位、定子铁芯的外形缺口形成孔、内孔及安装孔冲裁工位、定子铁芯用粘接剂喷涂工位、定子铁芯落料回转工位,冲裁落料形成铁芯成品,从模内直接输出各薄板相互粘接的转子铁芯和定子铁芯,大幅度改善了铁芯质量。

Study on semantic-oriented hybrid indexing strategy of resource metadata in peer-to-peer network

Applying ontology to describe resource metadata richly in the peer-to-peer environment has become current research trend. In this semantic peer-to-peer environment, indexing semantic element of resource description to support efficient resource location is a difficult and challenging problem. This paper provided a hybrid indexing architecture, which combines local indexing and global indexing. It uses community strategy and semantic routing strategy to organize key layer metadata element and uses DHT (distributed hash table) to index extensional layer metadata element. Compared with related system, this approach is more efficient in resource location and more scalable.
