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，得出不同条件下液压成形液压力Pi的工作压力范围.

Abstract:

According to the basic assumption of the composite pipe, the stress state during the hydraulic expansion process of the composite pipe is analyzed. Using the elastoplastic theory, the stress-strain relationship between the inner pipe and the outer pipe of the composite pipe is discussed, and the deformation coordination conditions of the circumferential strain of the inner and outer pipes of the composite pipe are used to calculate the correlation formula of the residual contact pressure Pc* between the hydraulic expansion force Pi and the inner and outer pipes of the composite pipe, and the working pressure range of the hydroforming fluid pressure Pi under different conditions is obtained according to the different residual contact pressures during the forming process of the composite pipe.
