采用三维实体单元对ＹＥ２０００型液压式材料试验机机身进行了静动态有限元计算，静态计算求出了给定工况下的应力位移数值，模态分析则给出了机身振动的前八阶固有频率及相应振型，这对于了解我国现有材料试验机的力学性能以及改进原有设计结构将具有重要意义。同时，在对原结构静动态有限元计算结果进行充分分析的基础上，提出了进一步的改进建议，对新改进结构重新分析计算结果表明，该方案在保证原设计要求的基础上，可将整机机身重量降低百分之十五。目前该成果已应用于实际生产，并取得良好的经济效益，为国家节约了大量的原材料。
The static and dynamic finite element calculation of YE2000 hydraulic material testing machine body is carried out by using three-dimensional solid element, the stress displacement value under given condition is obtained by static calculation, the top eight Order natural frequency and the corresponding vibration mode, which is of great significance for understanding the mechanical properties of the existing material testing machine in our country and improving the original design structure. At the same time, based on the sufficient analysis of the static and dynamic finite element calculation results of the original structure, further improvement suggestions are put forward. The re-analysis and calculation results of the new improved structure show that, on the basis of ensuring the original design requirements, Machine body weight decreased by 15%. At present the results have been applied to the actual production, and achieved good economic returns, saving a lot of raw materials for the country.
