基于直升机起落架着落动力学原理和LMS软件平台，建立了某型直升机起落架着落性能的虚拟仿真模型，研究着陆、着舰情况下由环境温度引起的轮胎压力变化对起落架载荷的影响。结果表明：起落架着舰载荷比着陆载荷提高80%~90%左右；着陆时若因温度变化引起轮胎压力从0.3 MPa上升至0.4 MPa，那么起落架载荷峰值将提高2 kN左右；着舰时若因温度变化引起轮胎压力从0.6 MPa上升至0.8 MPa，那么起落架载荷峰值将提高5 kN左右。

Based on the PrinciPle of helicoPter landing gear dynamic and LMS Virtual. Lab,a model for dynamic analysis of helicoPter landing gear is established to search for the effect of the variation of tire Pressure which leaded by the environment temPerature. The results indicate that landing on board increase struts forces by 80% ~90% than on ground. The variation of tire Pressure can not change the Peak value of the struts forces when landing on ground,and it will increase the Peak value of the struts forces by 5 kN if the tire Pressure changes from 0. 6MPa to 0. 8 MPa.
