针对目前对锅炉元件强度模拟性适应范围的不同见法,本文基于相似理论提出在弹性范围、弹塑性范围(包括蠕变现象)及破裂(高温、常温)条件下都可以进行模拟的依据,并给出不同条件下模拟时应遵守的条件及模拟实验结果的推广方法;文中还介绍了强度模拟实验应注意的问题。本文所述内容也适用于其他设备,如化工设备、原子能设备等。 In view of the current differences in the simulated adaptation range of boiler component strengths, this paper proposes the basis for simulations based on similarity theory under the conditions of elasticity range, elastic-plastic range (including creep phenomenon) and rupture (high temperature, normal temperature), and The conditions that should be obeyed under different conditions and the generalized methods of simulation results are given. The problems that should be paid attention to in the intensity simulation experiment are also introduced. This article also applies to other equipment, such as chemical equipment, nuclear energy equipment.
