Abstract
Vibration isolation is essential for minimizing the transmission of unwanted vibrations to sensitive equipment and structures. This study investigates a novel diamond-shaped vibration isolation system designed for effective low-frequency isolation, offering a balance of high stability and cost efficiency. The system’s unique spring configuration and damping characteristics are analyzed theoretically to derive governing equations. Numerical simulations are conducted in MATLAB using key parameters such as stiffness, damping co-efficient and mass. Experimental validation is performed using accelerometers mounted on the base and top platform to capture time-domain and frequency domain vibration signals. Results demonstrate a significant reduction in vibration transmissibility, as confirmed by root mean square (RMS) and frequency spectrum analysis. It was observed that the amplitude at the base is greater compared to that at the top platform, which indicates the system’s effectiveness. These findings suggest that the diamond-shaped isolator can significantly improve the performance and reliability of vibration-sensitive applications across various engineering domains.
