| 摘 要： | 碳纤维复合材料在工业上的应用越来越广,但对其材料性质的研究还远不充分。为了节省试验经费,应在进行必要试验的同时对碳纤维复合材料的性质进行模拟计算。本文针对一标准试验,利用ANSYS软件的节点耦合技术和接触分析技术分别对某碳纤维复合材料制成的NOL环进行了拉伸破坏载荷下的强度计算,给出NOL环上各点的周向应力。结果发现,这两种模拟方法与试验值的误差分别为23.6%和5.6%,表明接触分析技术比较精确。

| Abstract: | Carbon fibre composite materials are more and more used in industries,but the research on the properties is not deep enough.To save test cost,it is necessary to carry out theoretical simulation for the materials while performing experimental investigation.In this paper,ultimate strength of a carbon fibre composite material with a standard testing NOL-ring was calculated numerically by using ANSYS software with two simulation methods,namely node coupling and contacting.Circumferential stresses along the NOL-... |
