  • Ambient Vibration Testing of a Dam, Canada - Case Study

    The measurements and analysis presented here are performed by Professor Carlos Ventura, University of British Columbia, Vancouver, Canada. This case consider measurements conducted on a Canadian dam. The dam is 130 m long and 58 m high, and built in 1930. The measurements were conducted using an 8-channel measurement system. The sensors were Kinemetrics Episensor, forced balanced ...

  • Ambient Vibration Testing of a Bell Tower, Switzerland - Case Study

    The measurements and analysis presented here are performed by Dr. Reto Cantieni, RCI Dynamics, Switzerland. This case consider measurements conducted on the bell tower of the St. Peter & Paul church in Zürich, Switzerland. The measurements were conducted using a LMS Pimento data acquisition system. The sensors were PCB 93B31 accelerometers. The ...

  • How to ensure successful acceleration enveloping

    Following the interest shown in our recent blog discussing acceleration enveloping, the sophisticated signal processing technique that helps to pinpoint bearing failure at an early stage, we thought it would be a good idea to explain how to successfully implement it. ...

  • Dynamic Behavior of the Bumpy Road Shaking Table System

    Vibration tests were performed on the “bumpy road shaking table” system at the Cambridge University Geotechnical Centrifuge to investigate its dynamic behavior under operating conditions. In these tests, steel plates of known weights were fastened onto the base of the model container. The container was then subjected to “earthquake motions” simulated by the shaking table system and the ...

  • HAV mis-measurement – to no standards whatsoever…

    Misunderstanding Hand Arm Vibration monitoring marketing material can put hands and safety policies at risk. Caveat emptor. We are regularly asked about new vibration measurement technology, particularly re the latest hand-held, glove or wrist mounted transducers that are presented as the latest assessment improvements. Whilst they may be useful tools, unfortunately some claims have been ...

  • Modal Analysis of the Heritage Court Tower, Canada - Case Study

    The measurements and analysis presented here are performed by Professor Carlos Ventura, University of British Columbia, Vancouver, Canada. The building considered is the so-called Heritage Court Tower, which is located in downtown Vancouver, British Columbia, Canada. It is a relatively regular 15-storey reinforced concrete shear core building. The building is located on top of an underground ...

  • Opening the envelope on bearing vibration

    A sophisticated signal processing technique can help to pinpoint bearing failure at an early stage. Chris Hansford, Managing Director at Hansford Sensors, explains. Experienced operators can often tell if a machine is not working properly, on the basis that is does not ‘sound right’. The same principle can be applied – using modern electronics – to identify the exact cause ...

    The information described in this case study is by courtesy of the European research projects “Integrated European Industrial Risk Reduction System (IRIS)” and “Internet based Structural Monitoring System (ISMS)”. Special thanks to H. Wenzel (VCE), M. Döhler (Inria), L. Mevel (Inria) and C.E. Ventura (UBC). Objective 1 This case study demonstrates the ...

  • Successful trunk main correlations in Australia, the land of long pipes - Case study

    The Aquasscan TM Successfully locates leaks at distances over 1KM in Sydney. The Gutermann Aquascan (Trunk Main) correlator provided a series of high performance correlations in trials performed in Sydney, Australia.  Sydney Water provided a 1.2 KM of 600mm OD Steel trunk main for a series of tests to be performed to evaluate the performance.  The testing was administered by ...

  • Hand-Arm Vibration - You MUST know your numbers

    Measuring an individuals’ exposure to vibration has never been more important as despite the Control of Vibration at Work legislation being in force since 2005, the reported incidences of HAVS and the number of fines issued (and cost!) has increased. The Regulations state that ‘To protect employees from Hand Arm Vibration Syndrome (HAVS), and to comply with the Vibration Regulations, ...

  • Operational transfer path measurements and analysis - Case Study

    As a developer of in-wheel powertrain, Elaphe Propulsion Technologies Ltd. has to make sure that it’s powertrain does not emit excessive vibrations, that will result in structure-borne noise. Since vehicle suspension is typically not considered to also perform as a motor insulation system, there is a lack of knowledge on specific vibration insulation properties, especially in higher ...
