When using 57B wire rod to produce card wire,the squashed wire after drawing often cracks.
针对 5 7B线材生产针布钢丝出现拉拔后钢丝压扁开裂的现象 ,应用理化检验手段 ,对线材、钢丝的化学成分、表面情况、金相组织等进行分析。
Based on the knowledge of the squash dynamic process of single steel tube and according to experiments concerned,the plastic behavior of multilaminate steel tubes subjected to radial impact is analysed,eight plastic hinges framework is established,the displacement and velocity fields of the steel tubes are described and the magnitufes of .
在单个钢管的动力压扁过程清楚的基础上 ,根据实验分析了多排钢管受径向冲击塑性行为 ,建立了八塑性铰机构 ,描述了钢管压扁位移速度场。
