摘　　要：设计与试制了不同规格的波形套试件,测试了其工作特性。建立了波形套工作状态下的数学-力学模型,求解了理论特性,并用ANSYS进行了数值模拟,理论解、模拟解与试验结果吻合。揭示了波形套的定量工作特性以及几何参数对其特性的影响规律:在最大外径不变时,随着波纹圆角半径的增大,特性曲线中弹性区的斜率增大,进入塑性变形所需要的压力亦增大;在波纹圆角半径不变时,随着波形套最大外径的增大,特性曲线中弹性变形区的斜率减小,进入塑性变形所需要的压力亦减小。波形套工作特性的理论与试验研究,为确立其设计方法,促使该类零件广泛应用奠定了基础。Different series of corrugated sleeves are designed and produced and the working characteristics are tested. Based on the ring shell theory, plastic theory, corrugated sleeve＇s math mechanics model is proposed, the theoretical working characteristics are calculated and numerical simulation is proceeded through ANSYS. Both of theory result and simulation result are consistent with the experiment result. The research of theory and experiment reveals the quantitative working characteristics of corrugated sleeve and the influencing rule of the geometric parameters. When the maximal diameter doesn＇t change, the slope of elastic curve and press of the plastic yielding point increase gradually as radius of corrugation part is increasing. When the radius of corrugation part doesn＇t change, the slope of elastic curve and press of the plastic yielding point reduce gradually as maximal diameter is increasing. The research founds an important basis to establish the design method and spur similar products to be applied in engineering practice on a large scale.
