Machinery manufacturer John Deere has improved the design processes of its engines with Brüel & Kjær’s Pulse Reflex analysis software.
In one case, John Deere’s European NVH team noticed interesting behavior in a physical prototype during a specific application. “We also noticed this issue in our US-based engine model and we wanted to correlate and see exactly why that was,” said USA senior NVH analysis engineer Kristie Iverson.
Conducting comparable testing across two continents was challenging, as there are so many variables that people can select, such as software settings and test approaches. By using Pulse Reflex, it was easy for the NVH teams to share and standardize test approaches. The USA’s NVH group created an analysis chain, which included various analysis types, and sent it out to other NVH engineers, who could simply drop the analysis chain into their copy of Pulse Reflex.
“After testing, the global NVH people could just stick their data on the internal network and I could run it through my software in no time. Then all my displays and all my axes are set up the same. We’re looking at the same thing, so I could be as confident looking at data collected in France as if I had collected the data myself,” Iverson said.
With tight integration of testing and CAE modeling, John Deere has increased the amount of design iterations that are feasible, so they can test more ideas and simultaneously analyze more precisely. This ensures its customers get top engine reliability, whatever their specific application or configuration.
Experts from Brüel & Kjær will be on hand at stand 1750 at Automotive Testing Expo Europe 2016 to discuss this software and more.
