摘要：根据对复合管的基本假设 ,分析了复合管液压胀合过程中的受力状态 .采用弹塑性理论 ,对复合管内管及外管的应力应变关系进行了讨论 ,并利用复合管内外管周向应变的变形协调条件 ,得出了液压胀合力Pi 与复合管内管与外管之间的残余接触压力Pc 的计算关联式 ,根据复合管成形过程中残余接触压力的大小不同 。
In this paper, according to the basic supposition, the load state of the clad pipe is analyzed during the process of the hydro-forming. With the elasticity-plasticity theory the stress and strain for the inner and outer pipe of clad pipe is discussed. By using the distortion matching condition the calculating formulas related hydro-forming pressure to the residual contact pressure between inner pipe and outer pipe are derived. And according to the varying value of the residual contact pressure, the varying range of hydro-forming pressure is given
