Maplesoft said it has integrated a library of hydraulics components into its MapleSim modeling, analysis, and simulation tool, making it easier for engineers to design hydraulics systems from within the tool’s environment.
Through a partnership with Modelon -- which offers systems simulation tools based on the Modelica and Functional Mockup Interface industry standards -- Maplesoft is offering the MapleSim Hydraulics Library from Modelon.
A Canadian subsidiary of Cybernet Systems Co. in Japan, Maplesoft offers computation engine and physical modeling technologies in tools for design, modeling, and high-performance simulation. MapleSim provides a tool for physical modeling and simulation at the system level, allowing engineers to combine hydraulic subsystems with other aspects of a design and to analyze interactions.

Dr. Laurent Bernardin, executive vice president and chief scientist at Maplesoft, said in a press release that the library gives engineers a closer view of how hydraulics (which can be tricky to model and simulate) fit into the system design picture. "Hydraulics systems are notoriously difficult to model with high accuracy, but so important to understanding system-level behavior."
The library includes more than 150 components for modeling pumps, motors, cylinders, restrictions, valves, hydraulic lines, lumped volumes, and sensors, and it allows engineers to do system-level modeling of hydraulics from directly within the MapleSim environment.
Components include those suitable for real-time and hardware-in-the-loop simulations, along with advanced components that consider physical factors and provide a precise view of system behavior. The new library allows designers to incorporate compressible oils and cavitation effects into models, Maplesoft said. Engineers can select from a set of predefined standard hydraulics oils or define their own.
System designers also can reuse, customize, and extend hydraulics components to suit the particular needs of a project, and they can control the level of model detail to meet specific needs. Additionally, the hydraulics library offers access to underlying system equations to provide advanced analysis, parameter optimization, and visualization in MapleSim.
Thanks, mrdon. I appreciate your comment and the real-world perspective on this. Not being an engineer myself, I depend on the perspective of readers like you for some of the more technical aspects of the technology I write about.
I agree that modeling hydraulic systems can be tricky because of fluid mechanics involve. Also, both static and dynamic conditions have to be considered when designing with hydraulics because of their steady state and transient motion behaviors related to the system application their being used in. Very nice article!
I realized that I failed to mention in this story that this is the first direct integration with an external library that Maplesoft has added to this tool. This speaks to the importance of facilitating the development of hydraulics as part of an overall system architecture and not separately from the rest of the components. I think it is a useful addition to the development environment.

In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
