摘　　要：This study proposes a general imperfect thermal contact model to predict the thermal contact resistance at the interface among multi-layered composite structures.Based on the Green-Lindsay(GL)thermoelastic theory,semi analytical solutions of temperature increment and displacement of multi-layered composite structures are obtained by using the Laplace transform method,upon which the effects of thermal resistance coefficient,partition coefficient,thermal conductivity ratio and heat capacity ratio on the responses are studied.The results show that the generalized imperfect thermal contact model can realistically describe the imperfect thermal contact problem.Accordingly,it may degenerate into other thermal contact models by adjusting the thermal resistance coefficient and partition coefficient.本研究提出了一种广义非完全热接触模型,用以预测多层复合结构界面间的接触热阻。基于Green-Lindsay(GL)热弹性理论,通过使用拉普拉斯变换方法,获得了多层复合结构温度增量和位移的半解析解,进而研究了热阻系数、局部系数、导热系数和比热容对响应的影响。结果表明,该广义非完全热接触模型能够更有效地描述非完全热接触问题。相应地,通过调整热阻系数和局部系数,它可以退化为其他热接触模型。
