摘　　要：介绍了一种利用碳纤维复合材料(Carbon Fiber Reinforced Polymer(简称)CFRP)做成的拉杆结构。由于CFRP属于各向异性材料,传统方法对拉杆进行接触分析存在很大困难。利用商业软件ANSYS对其进行了接触分析,主要包括304不锈钢悬置螺栓螺母、螺栓内锥孔与CFRP的接触分析,给出了接触分析中的最大应力云图和接触特征;并结合实验数据证实了结构的可行性。A Carbon Fiber Reinforced Polymer（CFRP） tie rod was introduced in this paper. Material properties of CFRP tie rod is anisotropic,which results in difficulties in theoretical contact calculation. Commercial software ANSYS was adopted to do contact analysis on CFRP tie rod,including contact between 304 stainless steel screw head and CFRP rod and contact between304 stainless steel screw head and nut. Contact stress and contact characteristics were discussed in this paper. Additional tensile test experiment for tie rod was set up. The test result is in accordance with the result of numerical analysis. Our CFRP tie rod was proved appropriate to support cold mass.
