U.S.-Turkey Cooperative Research: Free and Forced Vibrational Analysis of Cylindrical and Non-Cylindrical Helical Coil Springs Made of Composite Materials

描述：该奖项是对俄亥俄州阿克伦大学聚合物工程教授Erol Sancaktar博士和土耳其阿达纳Cukurova大学副教授兼力学系主任Vebil Yildirim博士的合作项目的支持。两人计划建立由复合材料(各向异性)制成的圆柱形和非圆柱形螺旋弹簧的自由振动和强迫振动问题的公式，并进行实验以验证分析结果。预计这项工作最终将导致开发一种将弹簧的固有频率与弹簧的设计参数(包括几何参数和材料参数)相关联的方法。科学上的好处包括开发和测试数学和数值方法，而技术上的好处包括提供工具，以便在各种产品中适当设计和使用复合弹簧。这些应用可能包括设计用于隔振、储能和在重量和耐化学性是主要考虑因素的条件下进行电力传输的弹簧。范围：该奖项将允许具有互补能力的美国科学家和土耳其科学家之间的合作。这位美国科学家为该项目带来了机械工程设计、聚合物和复合材料、制造和测试方面的经验和专业知识。他还可以接触到重要的复合材料制造设施和测试设备。这位土耳其科学家在分析和数值方法方面拥有经验和专业知识，她令人印象深刻的发表记录证明了这一点。她将能够利用阿克伦大学这位美国科学家实验室的广泛计算设施。这一提议符合在互惠领域加强美国与外国合作的国际目标。

9871129SancaktarDescription: This award is for support of a cooperative project by Dr. Erol Sancaktar, Professor of Polymer Engineering at the University of Akron, Akron, Ohio and Dr. Vebil Yildirim, Associate Professor, and Head of the Mechanics Division at Cukurova University in Adana, Turkey. The two plan to formulate the free and forced vibration problem of cylindrical and non-cylindrical helical coil springs made of composite (anisotropic) materials, and to perform experiments for verification of the analytical results. The work is expected to ultimately lead to the development of a methodology for relating the spring's natural frequency to the design parameters of the spring, which include geometrical as well as material parameters. The scientific benefits include the development and testing of mathematical and numerical methodology, while the technological benefits include the provision of tools for proper design and use of composite springs in a variety of products. The applications may include designing of springs for vibration isolation, for energy storage, and for power transmission under conditions where weight and chemical resistance are primary concerns. Scope: This award will allow collaboration between a US scientist and a Turkish counterpart who have complementary capabilities. The US scientist brings to the project experience and expertise in mechanical engineering design, polymeric and composite materials, manufacturing and testing. He also has access to significant composite manufacturing facilities and testing equipment. The Turkish scientist has experience and expertise in analytical and numerical methodology, as evidenced by her impressive publication record. She will be able to utilize the extensive computation facilities at the US scientist's laboratory at the University of Akron. This proposal meets the INT objective of increasing US-foreign collaboration in areas of mutual benefit.
