| 摘 要： | 本文在对大挠度弹性联轴器振动试验数据进行处理和分析的基础上，用拟合分解法以及阻尼等效原理，提出一个与振动位移幅值有关的非线性迟滞恢复力数学模型，分析表明，该数学模型能很好地描述联轴器的非线性动刚度和阻尼等动态特性对迟滞恢复力的影响，为深入研究船舶推进轴系的振动特性提供了联轴器的数学模型。

| Abstract: | In this paper. by processing and analyzing the experimental date for a highly flesible coupling with large displacement. and with the, fitting-dedcomposing method and the principle of damping equivalence, a mathematieal model to represent the nonlinear hysteretic restoring force, with referenoe to vibration amplitude,is proposed. Analyses that this model can describe the effect of nonlinear dynamic stiffness and the damping of the couplingon the nonlinear hysteretie restoring force very well. |
