The Modal Analysis of Special Purpose Flexure Spring for Ground Applications

Abstract

This research paper presents a comprehensive modal analysis of a special purpose flexure spring designed for ground applications. The study employed ANSYS Workbench software to investigate the natural frequencies of the flexure spring under different geometries and materials. Additionally, experimental measurements of the natural frequencies were conducted using an FFT analyzer to validate the numerical results. The results show that the proposed design significantly reduces electromagnetic interference and improves the performance of flexure bearings, thereby enhancing the accuracy and reliability of precision instruments. The findings of this research have implications for a wide range of applications in the aerospace, defence, precision instrumentation, medical devices, optical systems and scientific industries.
