Liebherr reference

“LMS Amesim supports the entire development

process at Liebherr Machines Bulle and allows

engineers to tackle technical challenges, which

would be difficult to do with a traditional

engineering approach.”

“LMS Amesim is well integrated in the development

process at Liebherr and is actively employed to

address two critical issues when designing axial

piston pumps: optimization of the swash plate

dynamic behavior and noise reduction.”

“By using LMS Amesim, the company has

decreased response time and increased bandwidth

frequency of the pump’s displacement

servomechanism.”

“The new simulation approach has enabled

Liebherr Machines Bulle SA to gain a better

understanding of the physical behavior of axial

piston pumps.”
