本文给出了模拟稳定状态下热应力的方法并开发了相应的软件系统,这里热应力具有构建元素并受局部温度、热流、热传送以及绝热等同步效应的影响.另外,温度的热膨胀系数的相关性也得到了全面的考虑.通过采用严格的能量守恒、极小化方法、线性代数方程Gauss解的收敛性以及实验数据,我们建立了具有区域温度分布结构性元素材料的热膨胀系数之间的关系.在获得具有分支并在局部温度、热流、热交换及热守恒等同步条件下构建的热应力条件问题的可能计算解的意义下,本文得到的详尽算法和方法相对来说更具有一般性.
This paper presents a method to simulate thermal stress in steady state and develop a corresponding software system where thermal stress has the building elements and is affected by the synchronization effect of local temperature, heat flow, heat transfer and adiabatic etc. In addition, the coefficient of thermal expansion The correlation has also been fully considered.By using the strict conservation of energy, the minimization method, the convergence of the Gauss solution of the linear algebraic equation and the experimental data, we establish the relationship between the coefficients of thermal expansion of structural elements with regional temperature distribution Relations.The exhaustive algorithms and methods presented in this paper are relatively more general in terms of obtaining possible solutions to the problem of thermal stress conditions that have branches and are constructed under conditions of local temperature, heat flow, heat exchange, and heat conservation. .
