摘　　要：对舰载机拦阻着舰过程中起落架减震支柱进行受力分析，并运用拉格朗日方程针对减震支柱冲程和起落架弹性两个自由度建立舰载机起落架拦阻着舰动力学模型，通过仿真计算，得到了飞机对称对中着舰拦阻、偏心距3m对称着舰拦阻和滚转角2°非对称对中着舰拦阻的起落架减震支柱载荷变化情况。结果表明：在拦阻着舰过程中舰载机起落架受到的冲击载荷在经过短暂时间震荡以后会趋于稳定；相比偏心对称着舰，滚转非对称对中着舰对减震支柱的影响更大些，在震荡的量上将更加剧烈。The landing gear damping strut in carrier-based aircraft arresting desk-landing was analyzed aiming at the runout of damping strut and the flexibility of the landing gear by using the Lagrange equation： Then it concluded the changing of landing gear damping strut with symmetrical and straight arresting, 3m of off-center distance arresting and 2° of rolling angle arresting after simulating. The conclusion showed that the landing gear damping strut would be stable after a short time concussion; roiling and unsymmetrical affected the damping strut more severe than off-center and symmetrical arresting, and the qualities of concussion also being more acute.
