Using Source Contribution Analysis (SCA) and Structural Animation (STA) in the DATS software for the analysis of complex structural dynamics This post uses Source Contribution Analysis (SCA) techniques and a…
As its name suggests Operational Deflection Shape analysis shows the vibration pattern experienced during normal operational condition. This is different to other structural vibration tests such as impact hammer tests, bump tests or shaker tests which require a more controlled excitation force and are used to determine specific characteristics of the structure under test, such as natural or resonant frequencies.
The video below shows some examples of structural animation using Prosig's DATS software. https://www.youtube.com/watch?v=QsVzk0wwcR0
Prosig are delighted to have been invited to attend the 10th International Conference on Recent Advances in Structural Dynamics (RASD) to be held at The Institute of Sound and Vibration Research (ISVR) at Southampton University on 12th – 14th July 2010.
Prosig engineers will be on hand to demonstrate the P8000 range of 24-bit data acquisition systems and the DATS software including some of the specialist add-ons including Modal Analysis, Structural Animation and Hammer Impact Testing.
Prosig have a long relationship with the ISVR with many staff, both past and present, having worked or studied there and so Prosig are very pleased to have been invited to exhibit at the conference.
The following application note shows the steps taken to perform structural analysis using a hammer impact test on an automotive exhaust pipe structure to improve the structural damping properties of the exhaust pipe mount. This application note follows up to a previous article – “Preventing Component Failure In The Fast Lane”.
A recent signal processing application note described how the Prosig sponsored Dalmeny Racing Formula Ford Team, whilst contesting the UK Formula Ford 1600cc championship, suffered several minor structural failures on a particular part of an exhaust pipe mount. Prosig dispatched a team of engineers, and after a brief survey of the damage, the engineers made an outline assessment. They concluded that “the exhaust itself is resonating at particular engine speeds. This is causing some shear forces in the mount. This in turn is causing stresses in the material leading to cracking and eventually failure.”(more…)
