油气式缓冲结构具有效率高、稳定性好的特点,被广泛应用于大型机械、运载工具等重要装备.在外部载荷的作用下,油气式缓冲器通过油腔和气腔的压缩与伸长,使油液通过阻尼孔,并利用气体压缩缓冲吸能.但这种设计使得隔离腔室的密封结构始终处于往复运动的不利工况,导致密封问题频发,进而影响油气缓冲器性能.针对某型机起落架缓冲器密封故障,开展O型圈密封故障分析、组合密封结构密封性能评估等研究,复现定位漏油、串气、密封件失效等故障,提出了相应的改进优化建议,评估了优化后组合密封结构的密封性能是否满足设计要求.
Seal Failure Analysis and Performance Optimization of Oil-Gas Buffer
The oil-gas buffer structure has the characteristics of high efficiency and good stability,and is widely used in important equipment such as large machinery and transportation vehicles. Under the action of external loads,the oil-gas buffer compresses and elongates the oil and gas chambers,allowing the oil to pass through the damping holes and absorb energy through gas compression buffering. But this design keeps the sealing structure of the isolation chamber in an unfavorable condition of reciprocating motion,resulting in frequent sealing problems and affecting the performance of the oil and gas buffer. In response to the sealing failure of the landing gear buffer of a certain type of aircraft,research was conducted on the analysis of O-ring sealing failure and the evaluation of the sealing performance of the combined sealing structure. The faults such as oil leakage,gas leakage,and seal failure were reproduced and corresponding improvement and optimization suggestions were proposed. The sealing performance of the optimized combined sealing structure was evaluated to determine whether it met the design requirements.
