摘要:

为获得双模式TBM刀具破岩试验台的振动特性,并以此对试验台的结构进行优化,采用ANSYS Workbench仿真软件,通过对预应力下的模态分析完成对试验台在工作状态下的数值模拟分析,得到试验台前8阶固有频率和振型,以体现其结构特性;然后使用模态叠加法对试验台进行谐响应分析,得到位移-频率响应图和应力-频率响应图。研究结果表明: 试验台的最大响应频率为145.47 Hz,能够验证试验台结构的抗振性能,并为试验台的下一步结构优化提供依据。

Abstract:

The vibration characteristics of the dualmode TBM cutter rock breaking test platform are analyzed, which can be used to optimize the structure of the platform. By using ANSYS Workbench simulation software, the numerical simulation analysis of the test platform under the working state is completed through the modal analysis under the prestressed force. The first eighth natural frequency and mode shape of the test platform are obtained, which fully reflects the structural characteristics. And then the harmonic response of the test platform is analyzed by modal superposition method, and the displacementfrequency response diagram and stressfrequency response diagram are obtained. The results show that the maximum response frequency of the test platform is 145.47 Hz, which verifies the antivibration performance of the structure of the test platform, and provides a basis for the next structural optimization of the test platform.
