Signal Processing for Time Domain Analysis of Impact Hammer Test Data
Abstract »The impact-hammer test is a widely known non-destructive vibration testing method to extract the modal parameters of a dynamic system. Due to the fast development of computing, time-domain analysis for data interpretation has now received increasing attention. To provide normalised and denoising data, appropriate signal processing is indispensable. This paper presents a practical study on data normalisation and denoising. Specifically, discrete wavelet transform (DWT) denoising filter and weighted moving average (WMA) filter are applied in sequence for denoising. The signal processing results on the impact hammer test of a steel frame are shown to verify the effectiveness of the proposed methodology.

Dr Ying WANG joined University of Surrey in February 2016. He received his PhD degree in Structural Engineering in the University of Western Australia (UWA) in 2010. After briefly working as a research associate in UWA, he joined Deakin University in October 2010, as a lecturer in Civil Engineering in School of Engineering. During his career in Deakin, he took a major responsibility in curriculum development and teaching, by developing four new units from scratch, including Theory of Structures, Steel Structures, Advanced Structural Analysis, and Structural Dynamics. To safeguard critical civil infrastructure under extreme loading and enhance their life-cycle performance, Dr Wang focus his research attention on the techniques to identify structural damage, to assess structural condition, and to protect structures under extreme loading. His contributions to research in structural engineering include the development of innovative structural damage identification algorithms, development and application of spectral element models and guided wave testing methods for civil structures and construction materials, and development of integrated structural health monitoring system using local and global methods. He attracted more than 10 grants from government and/or industry, including an ARC Discovery Project (DP130104332, $315,000) for 2013-2015 on the development of spiral-shaped steel fibre reinforced concrete against impact loading. His research findings led to invitations to present at the 6th International Conference on Structural Health Monitoring of Intelligent Infrastructure 2013 (SHMII6) and SHMII7 in 2015. He was invited to present his research findings in more than ten world-renowned institutions. He was invited as a guest editor to edit special issues for 3 international journals. He serves as an assessor of ARC projects and a regular reviewer for more than 10 international journals. Externally, Dr Wang is a founding member and executive committee meber of Australian Network of Structural Health Monitoring (ANSHM). He is an active member of another 4 professional associations, including Engineers Australia. He served in the Standards BD-031 Reference Group representing Concrete Institution of Australia, since 2013. He served as organisation chairman, invited session chair, and invited scientific committee member of 9 national and international conferences and/or workshops.
