基于温度场的特殊结构物承载力及热学性能研究

Research on bearing capacity and thermal property of special structure based on temperature field

运用大型有限元软件ANSYS,对基于温度场的特殊结构物承载力及热学性能进行了数值模拟和分析,研究了热—结构耦合的问题,为考虑温度场作用的这类结构工程设计提供了计算依据。并给出了在泡沫塑料层不同厚度的情况下,结构物内部温度随时间的升温曲线以及泡沫塑料层厚度关于时间的结构物内部等温曲线,具有一定的参考价值。

By use of the finite element software ANSYS , numerical simulation and analysis are done for bearing capacity and thermal property of special structure based on temperature field , thermal - structural coupling problem is also studied, which supply calculation basis to design of practical structure effected by temperature field. Furthermore , graph of inner temperature - time under different thickness of foam plastic and graph of inner equal temperature about foam plastic thickness - time are given, these have some reference value.
