摘　　要：飞机减震系统在各种状况下吸收功量的情况是设计、使用、维修等部门始终关注的重要问题之一。由于我国长期沿用前苏联强度规范,在某型飞机起落架使用与维修中存在着一些需要探讨和澄清的问题。本文通过对某型飞机主减震系统吸收功量的计算与分析认为,该机减震系统不存在长期以来一直认为的偏软问题,而是偏硬。在紧急情况下,认为飞机可以超载着陆,不必放油减重,减震系统吸收功量没有问题。The energy absorption during different situation for the aircraft shock absorbers is one of the important things to the departments of designing,service and maintenance.There are some problems need to discuss and clarify,because our 'Standard on military aircraft's strength' follows that of Soviet Union.After the energy absorption is calculated and analyzed,the results show that the performance is hardness and is not softness regarded by the people in a long term.The results also indicate the aircraft can land with overload in emergency,while the oil can not be discharged to decrease the weight,it is no problem for the energy absorption of the shock absorbers.
