摘　　要：概述了模态分析和响应谱分析的基本原理和方法,并利用有限元分析软件对油涡轮支架进行了相关分析和验证。通过改进结构避开共振范围并校核抗震强度,确保了设备运行的安全可靠性,论证所得结论为后续类似分析提供了指导性建议。In this paper, basic principles and methods of the modal analysis and the response spectrum analysis are summarized, and the finite element analysis software is used to analyze and verify the oil turbine bracket. It has ensured the safety and reliability of equipment in operation condition through improving the structure to avoid the resonance range and checking the seismic strength. The conclusions obtained in this paper provide guiding suggestions for the subsequent similar analysis.
