The natural frequencies characteristics of a mechanical system using modal analysis

摘要

The paper presents some results obtained during the finding optimal solutionprocess for a ground movement system of an aerial / terrestrial drone. Using drones inobservation and surveillance missions has numerous advantages, especially whentalking about calamity areas, or impossible to reach by humans due to terrainobstacles or due to mission restrictions (the danger of getting close to a certainposition, large area to observe etc.). In every case, using an aerial / terrestrial drone isan optimal solution. The advantages of combining aerial with terrestrial observation inone drone are explained in the paper. There are presented some aspects related tomodal analysis of the ground movement system and some experimental resultsobtained using the vibration stand. An analysis of the results is made and further worktasks are established.
