| Abstract: | Transient heating has a serious effect on the characteristic of structural natural vibration. Considering flat plate as the object of research, the analyses of structural transient temperature field and characteristic of structural vibration are presented with the conditions of thermal load. The calculation results show that structural temperature will increase evidently so as to have a serious effect on the characteristic of structural natural vibration during the process of heating. |
