Career: Dynamics of Threaded Fasteners in Aircraft Components and Orthopaedic Fixations

9501824 Hess在这一职业奖中，开发了使用螺纹紧固件的结构组件的动态模型。这些模型考虑了摩擦和振动的相互作用，以及螺纹件固有的动态约束和非线性。这些结构组件的动态模型，如飞机结构和矫形夹具，导致设计标准，最大限度地减少维护和结构故障，由振动引起的紧固件松动。该标准通过飞机组件和矫形固定组件的广泛实验进行了测试。该教育计划与本科生和研究生的产业合作伙伴关系补充和整合了在非线性振动和摩擦学领域的研究。

9501824 Hess In this CAREER award, dynamic models of structural assemblies using threaded fasteners are developed. These models accommodate the interaction of friction and vibration as well as the dynamic constraints and nonlinearities inherent to threaded components. The dynamic models of these structural assemblies, such as aircraft structures and orthopedic fixations, lead to design criteria which minimize maintenance and structural failure due to vibration-induced fastener loosening. The criteria are tested through extensive experiments with aircraft assemblies and orthopedic fixation assemblies. The educational program complements and integrates research in the areas of nonlinear vibrations and tribology with industrial partnerships at both the undergraduate and the graduate levels.***
