本文根据热弹性理论,求解了壳体在常量定常温度场作用下的热应力问题,并通过壳体相容方程给出与上述热应力相对应的当量静载,使壳体的热应力计算转化为静力分析问题,从而简化了壳体热应力的计算方法,这对各类受有温度作用的建筑屋盖、容器等具有一定实用意义。 文中还通过试验验证了上述当量静载与温度场的关系。 Based on the theory of thermoelasticity, this paper solves the thermal stress problem of the shell under constant constant temperature field, and gives the equivalent static load corresponding to the above thermal stress through the shell compatible equation, so that the thermal stress of the shell can be calculated and transformed. For the static analysis of the problem, which simplifies the calculation method of the thermal stress of the shell, which has certain practical significance for various types of building roofs, containers, etc. that are affected by temperature. In the article, the relationship between the above-mentioned equivalent static load and temperature field is also verified by experiments.
