The generalized displacement of installation point, structural damping coefficient and voyage et cie discount code elastic vibration frequency can influence the energy dissipation efficiency of load impact.Taking Global Hawk UAV as an example, the dynamic equation of rigid-elastic coupling elastic aircraft is established based on Lagrange method.The landing characteristics of the Global Hawk UAV are simulated by using the parameters of modal mass, generalized installation displacement, frequency and structural damping coefficient, and the influence of the parameters on buffer load and energy dissipation time.
The results show that the smaller the modal mass and the larger the generalized displacement of the installation point are, the lower of buffer My Mom Dad Is Well Trained Funny Cartoon Dog Gift For Dog Lover Personalized Shirt load is.The larger the generalized displacement of installation point and structural damping coefficient are, the smaller of the elastic vibration frequency and the faster of the landing impact dissipation rate are.
