LW Finder identifies ideal placement of strain gauges for accurate measurement of structural loads

TROY, Mich. – Oct. 7, 2015 – Altair today announced that LW Engineering Software AB has joined the Altair Partner Alliance (APA), adding LW Finder for accurate and controlled strain gauge placement for measuring structural loads.

"Common issues encountered by engineers include noisy data and misleading results when using strain gauges to measure structural loads,” said Shea Wilson, co-founder of LW Engineering Software. “We identified this gap and consequently developed LW Finder to determine optimal strain gauge placement and predict measurement errors to dramatically improve the quality of the measured data. We chose the Altair Partner Alliance to help bring LW Finder to market as we have always relied upon them for easy access to world-class engineering software."

LW Finder is able to overcome challenges of identifying the appropriate location when utilizing strain gauges to measure structural loads. It minimizes measurement error by identifying the ideal locations for these strain gauges, even in situations where the structure is complex and subjected to several load cases. By knowing this information upfront, users are able to achieve higher quality load data with fewer repeated tests, saving time and money as well as managing risks to help keep projects on schedule. LW Finder is also able to compensate for non-linear behavior, and can be configured to take the properties of individual strain measurement setups into account. The software allows for prioritization of load cases that are required to have minimum error and selects gauge locations accordingly.

“LW Finder is unique because it is able to identify the ideal placement for strain gauges in complex situations,” said Rajiv Rampalli, Vice President of Development for HyperWorks at Altair. “Altair’s customers can use this information directly in complex finite element and multi-body simulations to predict accurate stresses on components during their operation and improve their performance.”

LW Finder is most heavily applied in the automotive and heavy equipment industries to help engineers and technicians prepare for physical tests that will require strain gauge measurement of the structural loads. The software is most often used for structures that are expected to have a relatively linear relationship between load and measured strain. It also addresses more complex problems, such as non-linear effects (i.e. plastic deformation), in the “Extra Errors” module.
