Abstract

This research discusses the static and dynamic analysis of the landing gear structure of an unmanned aerial vehicle (UAV). The dimensional study is conducted to investigate the effect of landing gear dimension variation on UAVs’ static strength and dynamic response. Static analysis was performed with Finite Element Method (FEM) software. The dynamic response of the UAV is analyzed using a single-degree-of-freedom vibration model. Based on the static analysis results, the landing gear stiffness and strength can be increased by increasing the width and decreasing the height, radius, and length of the landing gear structure. The energy dissipation in the dynamic analysis is described by hysteresis and viscous damping model. The dynamic response simulation results show that the increase in the stiffness of the landing gear leads to an increase in force transmission and acceleration of the UAV. Furthermore, the UAV response using the viscous damping model can accurately predict the system’s response with the hysteretic damping model for small damping conditions. However, the deviation was observed for large damping conditions.

起落架尺寸变化对无人机静强度和动态响应的影响

对某型无人机起落架结构进行了静动力分析。为研究起落架尺寸变化对无人机静强度和动态响应的影响，进行了尺寸研究。采用有限元软件进行静力分析。采用单自由度振动模型对无人机的动态响应进行了分析。根据静力分析结果，可以通过增大起落架结构的宽度，减小起落架结构的高度、半径和长度来提高起落架的刚度和强度。动力分析中的能量耗散用滞回和粘性阻尼模型来描述。动态响应仿真结果表明，起落架刚度的增加会导致无人机的力传递和加速度的增加。此外，在小阻尼条件下，采用粘性阻尼模型的无人机响应可以准确地预测采用滞回阻尼模型的系统响应。然而，在大阻尼条件下观察到偏差。
