Vibration modal analysis on the airplane landing gear
摘要
Abstract
The finite element model of the airplane landing gear was established with ABAQUS. Inhere frequencies and mode shapes of landing gear under fixed boundary conditions were worked out by. using Lanczos which is the most popular method to solve modal analysis in engineering; the low-level natural frequency was analyzed by the brake-induced vibration test. The simulation and test results showed the first natural frequency is about 30Hz. The result of modal analysis can be used to the design and improvement of landing gear.关键词
