针对有限元方法求解嵌固板温度应力存在计算模型复杂、工作量大等问题,在一维差分算法的基础上,建立了温度场差分模型,利用广义虎克定律和嵌固板特性,推导出嵌固板温度应力差分模型,并通过实例对嵌固板温度和应力进行求解。结果表明,差分算法求解嵌固板温度应力场与有限元求解结果一致,且效率较高,可为类似工程提供参考。 Based on the one-dimensional difference algorithm, a finite element method is used to solve the problem of the temperature stress of the embedded plate. The differential temperature field model is established. Based on the generalized Hooke’s law and the characteristics of the embedded plate, The difference model of the thermal stress of the embedded plate is solved, and the temperature and the stress of the embedded plate are solved by examples. The results show that the difference algorithm solves the temperature stress field of embedded plate consistent with the result of finite element analysis, and has high efficiency and can provide reference for similar projects.
