Hello, I’m Francesca Furno with Siemens PLM Software.
Today, I am going to present our system simulation solutions
helping you design high-performance hydraulics.
Hydraulic component and system suppliers face multiple engineering challenges
such as increasingly stringent customer requirements,
drastically reduced development costs and time-to-market.
Pump and valve suppliers for various applications, such as automotive, aerospace, oil and gas,
industrial machinery and energy, need to optimize the dynamic behavior of hydraulic
components while reducing physical prototyping to just the strict necessity.
System simulation brings you the right answers for the optimal development of today’s hydraulic
components and systems.
The LMS Imagine.Lab platform and its hydraulics solutions help you efficiency design
new hydraulic technologies by using a very large collection of hydraulic components.
LMS Imagine.Lab hydraulic simulation models are numerically stiff.
The solver automatically and dynamically selects
the most adapted integration method and time step.
LMS Imagine.Lab enables you to perform scalable mechanical modeling, 1D, 2D and 3D.
It provides interfaces with major multi-body software and offers import/export capabilities
for control integration to perform model-in-the-loop, software-in-the-loop
and hardware-in-the-loop simulations.
First, let’s take a look at LMS Imagine.Lab capabilities for hydraulic pumps design.
The hydraulics solution allows you to properly size hydraulic pumps while limiting volumetric
losses due to leakages.
Moreover, you can greatly improve the intake and delivery sections, the piping design and
the internal geometry to reduce flow and pressure ripples.
The solution enables you to control pump flow generation by improving the regulation of
the displacement devices and the stability of pump regulating valves.
You can also early evaluate pump integration issues within the complete system, and achieve
the best tradeoff between various attributes
such as performance, energy consumption, NVH and durability.
Second, I would like to talk about the value LMS Imagine.Lab offers
for hydraulic and electrohydraulic valves design.
The solution is suitable for analyzing valve performance for achieving specific targets,
such as flow rate characteristics, regulated pressure, and controlled flow
while reducing losses.
Moreover, you can improve the stability of valves’ regulation by optimizing the damping,
adopting a smooth fluid power modulation at the beginning of the opening while also keeping
fast port pressurization and reducing stick-slip.
You also will be able to evaluate valve integration issues earlier, including modal couplings
between components through lines and stability of controllers.
Finally, how does LMS Imagine.Lab help you with hydraulic systems design?
It allows you to design high-performance and energy-efficient hydraulic systems by developing
smart control strategies.
Consequently, you can assess and improve the overall hydraulic system behavior.
With this solution you will easily define the impact of actuators on mechanical structures
and solve vibration and noise issues generated by the coupling between fluid components,
mechanical and electrical systems.
To conclude, LMS Imagine.Lab offers you a powerful integrated simulation environment,
which allows you to assess the dynamic performance of hydraulic components and systems in order
to evaluate design modifications of existing architectures,
or to develop new ones at a predesign stage.
Thank you for watching.
