着陆工况下飞行汽车动力学建模与冲击载荷分析
Dynamic modeling and impact load analysis of flying cars during landing scenarios
摘要
Abstract
With the growing load capacity of flying cars,the research on the impact load characteristics during the landing process has become increasingly critical.This paper proposes an integrated multibody dynamics modeling and simulation method for a heavy-duty flying car under vertical landing conditions.First,a 10-degree-of-freedom full-vehicle dynamics model is built based on Kane's method,incorporating the six-degree-of-freedom motion of the vehicle body and the vertical motion of the four wheels,thereby describing the coupling mechanism of the vehicle body,suspension,and tires during landing.Through numerical simulation,the dynamic load responses at key connection points are analyzed when the flying car lands vertically at a speed of 1 m/s,and quantitative analysis of the load spectrum and frequency spectrum is completed.The results indicate the impact load on the suspension system is the most significant during landing,with the maximum load occurring at the upper spring mounting point,while the impact on the steering system is relatively minor.Frequency spectrum analysis reveals no significant resonance frequencies in the suspension components,whereas the steering connection points exhibit a pronounced dynamic response in the extremely low-frequency range(<1 Hz).The model developed in this paper effectively simulates the entire dynamic behavior of the flying car from touchdown to stabilization.The findings provide a simulation basis and theoretical reference for the structural design,load assessment,and dynamic optimization of landing systems in flying cars.关键词
