Abstract

The use of numerical simulation presents an opportunity for advancements in aircraft seat design while upholding rigorous safety standards. This study is focused on the development of three numerical models for simulating dynamic tests to certify aircraft seats, including a simplified Multibody model, a Multibody model with plastic hinges and a Finite Element model. The accuracy of these models was assessed by comparing simulation results with experimental measurements. The findings indicate that these models have the potential to serve as valuable tools for designing and enhancing aircraft seat configurations as well as streamlining the certification process. Providing accurate results with low computational time, Multibody models serve as an efficient and cost-effective approach for assessing seat performance while emphasizing occupant safety.
用于动态认证试验模拟的飞机座椅组件和乘员数值模型的开发和评估
数值模拟的使用为飞机座椅设计的进步提供了机会,同时坚持严格的安全标准。本研究的重点是开发三种用于模拟飞机座椅动态试验的数值模型,包括简化的多体模型、带塑性铰链的多体模型和有限元模型。通过将模拟结果与实验测量结果进行比较,评估了这些模型的准确性。研究结果表明,这些模型有潜力成为设计和改进飞机座椅配置以及简化认证过程的宝贵工具。多体模型以较低的计算时间提供准确的结果,在强调乘员安全的同时,为评估座椅性能提供了一种高效、经济的方法。
