一、开展高温应变电测技术研究的重要意义现代力学最重要的特点之一,往往要考虑热、电磁、辐射等因素的影响,其中高温环境影响尤为突出。我国科技规划的几个重点领域(如能源、空间、材料、高能物理等),至少有一半涉及高温力学问题。工程中存在的热应力问题也相当普遍,有些还伴随高速和高压,使问题更复杂化。从目前发展的水平看,现代机械遇到的高温条件大致如下:
First, to carry out the significance of high temperature strain measurement technology research One of the most important characteristics of modern mechanics, often to consider the heat, electromagnetic, radiation and other factors, including high temperature environment is particularly prominent. At least half of the key areas of China’s science and technology planning (such as energy, space, materials, high-energy physics, etc.) involve high-temperature mechanics. The thermal stress problems that exist in the project are also quite common, some of which are accompanied by high speed and high pressure, making the problem more complicated. From the current level of development, modern machinery encountered high temperature conditions are as follows:
