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3 m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 force analysis of the landing struts shock absorption pillars during the blocking of the carrier aircraft was carried out. The Lagrange equation was used to establish the carrier landing gear for the two degrees of freedom of the strut and the landing gear. The simulation results show that the landing loads on the landing gear of the aircraft are symmetrical, and the changes of landing loads on the landing gear are obtained. The results show that the impact load on the landing gear of the carrier-based aircraft during the blocking of the ship will tend to be stable after a brief period of shock. Compared with the eccentric symmetrical ship, the impact of the roll-on asymmetric landing on the shock-absorbing pillar Larger, in the amount of shock will be more intense.
