摘　　要：对航空不锈钢管路冷挤压连接技术开展了研究,建立了冷挤压式管路连接结构的理论模型,利用ANYSY对理论模型进行了仿真分析,并对仿真分析进行了实验验证。结果发现,仿真分析与实验验证的结果基本一致。对冷挤压管路连接技术的连接机理进行了分析,结果表明变形力是冷挤压连接强度的重要来源。The aero stainless steel tube ＇connecting is explored in the paper, which is modeled and simulated with ANSYS, and the simulation results are verified by the experiments. The theoretical and experimental results coincide well with each other. Through the analysis of the cold extruding connecting mechanism, the deforming force is played as an important role of connecting strength.
