摘　　要：工业软管泵软管在使用过程中工作条件较为恶劣,在使用寿命和可靠性方面存在较大优化设计空间,对其进行快速、精确地数值模拟十分必要。考虑到橡胶复合材料高度的非线性和几何非线性,文中为工业软管泵中使用的非编织橡胶软管设计了一个非线性数值模型,并建立了一种用于处理非编织物加强层的加强筋单元有限元模型。基于以上模型,进一步研究了反作用力、最大应力应变和软管内表面接触面积大小与滑靴压缩进给量的关系,通过这些参数确定滑靴的挤压位移,能够减少原型测试的时间并降低设计成本;同时还计算出在不同内部压力下密封软管的预测挤压位移。针对软管压缩过程设计了反力和变形尺寸测试试验,结果表明:仿真结果具有良好的精度。文中提出的软管泵软管建模方法有助于软管泵的全虚拟仿真和数字化设计。Since the hose for the industrial hose pump is often used in harsh working conditions,improvement should be made in terms of the hose’s service life and reliability,and numerical simulation should be conducted in a rapid and accurate manner.In this article,with the rubber composite’s high-standard material and geometric non-linearity taken into consideration,a non-linear numerical model is set up for the non-braided rubber hose for the industrial hose pump,and a finite-element model of the reinforced bar is constructed,so as to deal with the reinforced layer of non-braided fabrics.In addition,further research is conducted on the relationship between the reaction force,the maximum stress-strain,the contact area of the hose’s inner surface,and the sliding shoe’s compression feed rate.These parameters are used to identify the sliding shoe’s compression displacement,which is helpful to shorten the prototype’s testing time and lower the design cost.At the same time,the predicted compression displacement of the sealed hose with different internal pressures is calculated.Efforts are made to design the test on the hose’s reaction force and deformation size when the hose is compressed.It is shown that the simulation results have good accuracy.The modelling method is helpful for full virtual simulation and digital design of hose pumps.
