MotionSolve Flex Multibody Dynamics Analysis and Radioss Explicit MBD Analysis Stress non-convergency

Recommended Posts

Hello,

 

i am a graduate student in ITU Aeronautical Engineering(IDP). i am preparing my thesis. The issue of my Thesis is Flexible multibody analysis of a Landing Gear of a Training Plane.

When i analysed the system, i need to compare the results with real test datas. i couldnt achive tests, because of time constraints and very expensive. i think that the closest results can be explicit dynmaic analysis. when i arrenged the explicit dynmaics model and run. i saw there arent any correlation between flex mbd and exp. dynamics anylsis in the same boundry conditions.

Can you help me to solve this problem.

i asked this question to turkish distrubuter, they get rid of me because of thier job jam.

Unfortunately my deadline is very strict, i have to deliver the thesis as soon as possible.

My all datas ar in the link below. The model, solved files and the video files.

in this problem when the plane landed, the oleo strut make displacement 160mm. During this action observing stresses on the structure, and the 434 steel's compitability for this work.

 

i will be happy for helping me.

Thanks for everything.

 

Best Regards.

Yours sincerely.
