| 摘 要： | 金属拉伸力学性能因拉伸温度和拉伸速率的改变引起测试不确定性，导致在一个温度一个应变速率下的拉伸试验结果，一般不是被测金属的原始力学性能。拉伸试验新技术体系表明，越快的拉伸应变速率，“力学性能 拉伸应变速率”曲线上的力学性能越接近原始力学性能。存在充分快的拉伸应变速率，在“力学性能 拉伸应变速率”曲线上能获得原始力学性能。同时给出了确定这个能获得原始力学性能的充分快应变速率的方法。

| Abstract: | As viewed from the structure of reactor, the theoretical analysis of vibration property of reactor is presented. Based on vibration theory and finite element method, a computer program is developed to perform analysis of dynamic response of reactor to earthquake. In this research work, structural mode test and vibration test are conducted to validate the computational results. A model test of reactor structure pilot research work is done on by simulating actual earthquakes. |
