Design and Analysis of Shock-Absorbing Systems for Multi-terrain Drone Through Finite Element Analysis
摘要
Unmanned Aerial Vehicles (UAVs) are becoming indispensable tools across various fields due to their ability to navigate to remote and inaccessible areas, delivering crucial data for scientific research, disaster relief, and other critical operations. However, these advanced UAVs face significant risks from high-impact landings due to technical failures, adverse weather conditions, or unforeseen circumstances. The proposed work addresses this critical challenge by developing an innovative shock-absorbing system for drone legs, integrating magnetic and spring components. The system aims to enhance drone resilience and operational capacity across diverse terrains while significantly reducing the risk of potentially catastrophic irreparable damage to the drone during free falls. This manuscript outlines a design and development plan for an innovative suspension system to mitigate the effects of high-impact landings by the shock-absorbing system, which integrates both spring and magnetic components to enhance the drone's stability and adaptability. The adaptive system has been designed to assurance optimal landing stability and adaptability to various terrains. The spring mechanism and magnetic suspension, powered by neodymium magnets (N35 or N52), mitigate sudden impact forces on uneven surfaces. The system's performance has been identified through structural analysis using ANSYS Software, as well as employing Gilbert's model of magnetic theory to accurately model the magnetic repulsive force between two cylindrical magnets. Future research will focus on improving drone manoeuvrability, integrating advanced sensors, and exploring new applications to further extend the capabilities and impact of these versatile unmanned systems.
