Operational Modal Analysis of Broaching Machine
Applied Mechanics and Materials, 2012Modal parameters for LG51SH broaching machine from operational responses are studied to examine the dynamic properties of mechanical structure. The operational modal is analyzed using PolyMAX method with responsive data of key point in broaching machine, which is excited in practical broaching operation and tested by LMS SCADAIII-105 system.

Operational Modal Analysis of Aluminum Beams
Journal of the IEST, 2007Natural frequencies obtained by modal analysis are important to engineers interested in predicting the dynamic behavior of structures. Traditional modal analysis involves impact testing or shaker testing, where response signal and input force are measured to obtain the transfer function. However, for large structures, input excitation force measurement

Operational modal analysis by thermoelasticity
2009In this work the theoretical and practical possibility of using a new measurement technique, based on high speed thermographic acquisition systems, for the study of the dynamic response of objects has been demonstrated. This methodology has been named thermoelastic modal stress analysis (TMSA).

Subspace identification for operational modal analysis
2010This chapter deals with the estimation of modal parameters from measured vibration data using subspace techniques. An in-depth review of subspace identification for operational modal analysis is provided. In addition, two recent developments are emphasised: the estimation of the probability density function of the modal parameters, and the use of an ...
