在航空航天领域的设计方面,不断努力提高燃料有效率,战术机动性和有效负载能力驱使设计工程师们研究大量的战略,通过大量使用轻质材料,如复合材料,铝和塑料来减缩质量。然而,轻质材料的使用会产生其他的危害。一个次要的问题出现了:找到安全可靠的紧固件装配的方法,可以防止紧固件松动,同时最小化装配和维修成本。这些方法必须保证在航空航天环境中,冲击,震动和热循环恶劣条件下连接处的完整性。
In the field of aerospace design, continuous efforts to improve fuel efficiency, tactical mobility and payload capabilities have driven design engineers to explore a number of strategies to reduce quality through the extensive use of lightweight materials such as composites, aluminum and plastics. However, the use of lightweight materials can create other hazards. A secondary issue has arisen: Finding a safe and reliable way to assemble fasteners prevents loose fasteners while minimizing assembly and repair costs. These methods must ensure the integrity of joints at impact, vibration and thermal cycling in aerospace environments.
