ours is oleo pneumatic type this is modeled as mass spring damper system the landing gear system is a tricycle type.

5126 is the mass and it should bounce because its landing on a aircraft carrier. we have to assume the time thanks

the maximum deflection has been provided which = 0.3 m (Value Assumed ) For lynx 300 Helicpter Mass of the helicopter = 5126 Kg sink speed = 0.5m k= F/x = 5126/0.3 = 167620.2 N/m Need to find out damping ratio and Damping Coeficient at which the helicopter will have a deflection of 0.3 m

how to calculate the landing gear damping coefficient and stiffness for a non linear Spring type. I have only the mass of helicopter = 5126 Kg and initial velocity of 0.5m/s . Can anybody help please thanks
