摘　　要：偏置筒体结构由于其相对偏心距较大,其扭转振动效应一般较大,容易成为结构设计的控制因素。论文对偏置筒体进行弹塑性扭转振动效应分析,提出了采用PERFORM-3D对偏置筒体结构弹塑性扭转振动效应的敛散性补充分析的基本方法,并在此基础上,结合工程实例给出了关于偏置筒体抗扭转设计的一些建议。Due to the considerable eccentricity and large effects of torsional vibration, torsional vibration effect of eccentric tube s（a＇ucture are key issues in the design process. We analyze the eccentric tube slzucture by elasto-plastic torsional vibration analysis, apply PERFORM-3D to analyze the convergence ofelastoplast/c torsional vibration analysis. Furthermore, we offer effective advice based on both computational results and real projects for eccentric tube structure design.
