在许多国民经济部门中,胶管用作柔性管道体系。对胶管的气密性,耐腐蚀介质性能,耐寒性等传统要求并不能反映各种使用条件。对许多机组和液压系统使用的胶管要求是耐外界冲击载荷,其作用时间往往只有10~(-2)~10~(-1)秒,而且作用在胶管的一端。这种载荷的作用方向是任意的,此时胶管管体沿纵向变形。为了对各种结构、各种直径和各种长度胶管的骨架层进行研究,以及评价管接头的
In many national economic sectors, hoses are used as flexible piping systems. The traditional requirements such as the tightness of the hose, corrosion resistant media, and cold resistance do not reflect various conditions of use. The hose requirements for many units and hydraulic systems are resistance to external impact loads, and their operating time is often only 10~(-2)~10~(-1) seconds, and it acts on one end of the hose. The direction of action of this load is arbitrary, in which case the hose body is deformed in the longitudinal direction. To study the skeleton layers of hoses of various structures, diameters and lengths, and evaluate the fittings
