9500150 Sack The objective of the research that will be performed under this proposal is to experimentally demonstrate the effectiveness of a highway bridge vibration control system. A designated bridge will first be tested initially to establish a valid structural model (FEM). The identified model will then be employed to develop an optimized design for the retrofit of the bridge with the hydraulic semiactive control system. Once the new control system has been installed, then the performance of the bridge will then be monitored to determine the effectiveness of the design. If successful, the design should extend the useful service life of the bridge by several years at a small fraction of the cost that would have been realized to refurbish or replace the bridge. In order to accomplish the project, the proposal requests funds to purchase a structural modal testing system (SMTS). The SMTS will be used to acquire and analyze vibration data, and to identify the structural model of the bridge.

9500150麻袋根据这项建议进行的研究的目的是通过实验证明公路桥梁振动控制系统的有效性。一座指定的桥梁将首先进行初步测试，以建立有效的结构模型(FE)。识别出的模型将被用来为该桥的液压半主动控制系统改造开发优化设计。一旦安装了新的控制系统，然后将监测桥梁的性能，以确定设计的有效性。如果成功，设计应该会将大桥的使用寿命延长几年，而翻新或更换大桥的成本只是这一成本的一小部分。为了完成该项目，该提案要求提供资金购买结构模态测试系统(SMTS)。SMTS将用于获取和分析振动数据，并识别桥梁的结构模型。
