| 摘 要： | 通过某型飞机主起落架转轮机构的140连杆外场破坏及活塞杆上轴套使用中脱落下来的外场故障,清楚地揭示了起落架弹性变形引起的危害。人们应该对它引起关注。 本文给出了考虑弹性变形影响的支点载荷计算方法和系统内力的计算方法,还对特殊的弹性变形——缓冲器行程的重要性给予论述。

| Abstract: | The paper discloses the influences of landing gear elastic deformation arising from the damage of S aircraft main landing gear wheel-steering mechanism No. 140 link rod and the falling-off failure of piston rod shafe sleeve during operation in the field . Therefore attention should be taken on it.The paper provides the computation methods of pivot load and system internal force under the consideration of the elastic deformation impact . The special elastic deformation-importance of damper stroke is also described. |
