1995: first libraries for fuel injection during Engineering Services projects
Considering all the possible combinations of fluid components for different applications (here injection) in various
industries (Automotive, Aeronautics, Off-Highway, Mechanical Industries, …), it appeared that a generic approach
with some basic elements to assemble would be a much more efficient approach to address any use case.

Various industries involving any kind of fluid components
Too many cases to be addressed, need
for rational and flexible approach

• TF transformer
1995-1996: the concept of HCD (Hydraulic Component Design) was born
Benefits
• Generic
• Reusable
• Efficient
Motivations
• Flexible approach to model any kind of fluid components

Generic libraries to assemble bricks to get your physical systems
Generic elements are
used from different
categories. It’s similar

Design of Injection systems and Braking systems with HCD
Bosch reference
“The collaboration with the LMS Amesim development team started in 1997”
“Siemens PLM Software has proved to be an excellent partner, one that listens
closely to Bosch’s requirements and takes them into account in the LMS
Imagine.Lab roadmap.”
“More than 300 Bosch engineers use LMS Amesim in different locations
globally to create specific components”
“LMS Amesim helps specialists to study the dynamic subsystem and system
behavior ….. Using LMS Amesim, they also validate the control strategies of
components”
“… open simulation tools are critical to avoiding what otherwise is likely to
become a time-consuming and error-prone process.”
“Another very important advantage of LMS Amesim is its strong focus on
numerical performance and robustness”https://www.plm.automation.siemens.com/CaseStudy
