【摘要】 在航空器着陆过程中，侧向座椅的乘员在紧急制动时受到伤害的风险很高。为了提高乘员的安全水平，本文从座椅静强度性能研究的角度，根据适航要求设计了侧向座椅静强度试验。采用有限元分析方法，以某型直升机侧向座椅为例，对座椅的静载荷加载试验进行了仿真模拟。对仿真结果中不同静载荷实验下的应力分布和位移情况进行分析，初步验证了该型侧向座椅的结构与性能可靠性，为后续物理实验提供理论及技术支持。更多还原

【Abstract】 Emergency braking during aircraft landing puts passengers in side-facing seats at serious danger of injury. In order to improve the safety level of the occupants, this paper designs the side-facing seat static strength test according to the airworthiness requirements from the perspective of the seat static strength performance research. Finite element analysis method is used to simulate the static load loading test of the seat, taking the side-facing seat of a certain helicopter as an example. The stress distribution and deformation under different static loading experiments were analyzed in the simulation results, which initially verified the structure and performance reliability of this type of lateral seat, and provided theoretical and technical support for the subsequent physical experiments.更多还原
