Simulation Analysis Technique of Truck-like Landing Gear Based on ADAMS

A truck-like landing gear's simulation analysis was made using MSC/ADAMS,which is a kind of software for Virtual Prototyping Technology.Firstly,a landing gear prototyping model was established using CATIA and imported to ADAMS through SIMDESIGNER,which acted as a kind of interface software.Secondly,dynamic analysis of the landing gear's drawing back and putting down procedure and the impacting with the run way procedure were simulated with the established model.Finally,with the help of ADAMS' parametric design ability,the effect of some landing gear's parameters on the performance of the shock absorber and the distribution of the impact force was studied.Through this way,the integration of landing gear's design and analysis is realized and this new way also is proven to be practicable and can make great economic profit.
