Abstract
Aerial vehicle electronics, such as inertial measurement units (IMU), are subjected to aerodynamic forces and engine-induced vibrations during flight. Structural vibrations must be attenuated using vibration isolators to ensure these electronic devices operate effectively and the vehicle completes its mission successfully. Passive vibration isolators are typically placed between the vibration platform and the electronic devices to mitigate dynamic responses and prevent resonance. This paper investigates energy dissipation methods in mechanical systems, focusing on viscoelastic damping materials (VDM). These materials are ideal for energy dissipation due to their ability to deform and dissipate energy under load. By optimizing parameters and selecting an appropriate VDM, the performance of isolators can be significantly enhanced. In the study, vibration isolation components are designed for electronic devices, and elastic isolators are produced and validated through static and dynamic load testing. A comprehensive analysis of various material parameters transforms the system’s dynamics and shock level, ultimately enhancing the VDM model for effective vibration isolation and shock absorption. This study aims to provide a clear understanding of energy dissipation methods and required material properties, enabling the design of efficient vibration isolation strategies for IMU and other electronic devices on aerial vehicles.
