| Abstract | Firstly, taking the stability of the forestay bar as the restraint, the section area of the forestay bar was optimized from 1800 mm2 to 1178 mm2, with reduced weight of 16.1%. Secondly, the equivalent load of the forestay bar was obtained by using dynamics simulation software. Finally, the stress field and the fatigue life of the forestay bar were simulated. The results show that stress of the forestay bar with 929MPa can meet the requirement for its material strength, and fatigue life of 51200 times also satisfies the request of the nose landing gear. That is, material property of the forestay bar is utilized more than before, and its weight decreased successfully. |
