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

9501824赫斯在这个职业奖中，开发了使用螺纹紧固件的结构组件的动态模型。这些模型适应了摩擦和振动的相互作用，以及螺纹部件固有的动态约束和非线性。这些结构组件的动力学模型，如飞机结构和骨科固定装置，导致设计标准，以尽量减少维修和结构故障，由于振动引起的紧固件松动。该标准通过飞机组件和骨科固定组件的广泛实验进行测试。该教育计划补充并整合了非线性振动和摩擦学领域的研究，并与本科和研究生的工业伙伴关系进行了合作

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.***
