Rigid-flex Coupling Dynamic Analysis of Main Landing Gear Door Structure Based on LMS
Based on LMS Virtual.Lab software,a rigid-flex coupling dynamic model of a certain type of main landing gear door was established,and the flexible body instead of rigid body for analysis to simulate the real motion situation was used.The stress distribution of the rocker arms of the front and rear hatches was analyzed,and the modal analysis of the rocker arms was carried out by using Nastran.The rigid-flex coupling model is compared with the rigid body model,and the results show that the flexible body model could consider the deformation of the hatch,reproduce the actual situation of the hatch,and further optimize the structural design.
