Structure Analysis of FTIR Infrared Spectrometer Based on ANSYS/Workbench

Abstract:

The CAD software SolidWorks was used to create a three-dimensional finite element model of FTIR infrared spectrometer, and the model was imported into ANSYS/Workbench to modal analysis and harmonic response analysis. Through modal analysis, each order natural frequency and vibration shape were obtained. From modal shape analysis, all components of the stiffness strength and elastic deformation situation were got, and many times tests were carried to enhance stability of the structure and materials which had the most seriously deformation and direct effect impact to the quality of interferometer. The most sensitive frequency range of the system was concluded by harmonic response analysis, which provided a basis for further designing and improving of the spectrometer performance.
