摘　　要：热界面材料不仅是机载计算机中的重要传热部件,而且对机载计算机正常工作起着重要作用。该文设计了专用试验工装,基于试验模态分析和计算模态分析方法对其物性参数进行了测试,这不仅解决了热界面材料的物性参数无法通过力学实验测得的缺点,而且测试结果也为机载计算机力学仿真与设计提供重要基础数据。The thermal interface material is an important heat transfer component in the airborne computer, which plays an important role in normal operation of the airborne computer. The physical parameters of the thermal interface material are difficult to be measured by mechanical experiments, thus special experimental equipment is designed in this paper, and the physical parameters are tested based on the experimental modes and the calculated methods. It provides important basic data for airborne computer strength simulation and design.
