Abstract: This paper recommends that some uncertain parameters, such as discharge coefficient of a landing gear, can be evaluated by numerical method which simulates the drop test process of the land ng gear. This method can also be employed in the design stage of a landing gear for parameter optimization.

Key words: dynamic response, design of landing gears, drop test
