摘　　要：自紧工艺在身管加工制造中已经得到广泛应用,其中液压自紧和机械自紧在自紧身管上的应用已经逐步完善,但身管温度自紧还处于探索阶段,尚有广阔的研究前景。为深入探究身管温度自紧的力学性能,针对炮钢材料的身管,首先对温度自紧的身管进行计算,然后运用ABAQUS软件对未自紧身管和自紧身管进行分析,得到其在6种工况下的应力分布情况。仿真结果显示,经温度自紧工艺处理后的身管强度显著提升;通过身管承受膛压时的等效应力对比明确了最佳温差范围,为实际工艺应用提供了理论依据。The self-tightening process is been widely used in gun tube processing and manufacturing,in which the application of hydraulic self-tightening and mechanical self-tightening on the gun tubes is been gradually improved,but the thermal self-tightening of gun tubes is still in the exploratory stage,and there is still a broad research prospect.In order to investigate the mechanical properties of thermal self-tightening of gun tube,for the gun tube made of gun steel material,the thermal self-tightening gun tube is calculated firstly,and then ABAQUS software is used to analyze the non-self-tightening gun tube and self-tightening gun tube,and obtain the stress distribution under six working conditions.The simulation results show that the strength of the gun tube after the thermal self-tightening process is significantly improved;the comparison of equivalent stresses when the gun tube is subjected to chamber pressure clarifies the optimal range of temperature difference,which provides a theoretical basis for the application of the actual process.
