| 摘 要： | <正> 在计算飞机起飞、着陆和滑行等地面运动的静、动态载荷时,除了需要飞机结构和气动参数外,起落架减震器的性能参数更占有重要地位。而这些性能参数中尤以决定油液阻尼力的流最系数为重要。长期以来,国内主要靠查手册、凭经验确定这个系数,如果能较准确地确定流量系数,对载荷计算是很有意义的事。

| 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. |
