Model Based System Engineering of an ABS System

Model thermal-fluid system dynamics using 1D modeling & simulation (rather than using only 3D CFD) to yield nearly-as-accurate results significantly faster - to enable more design exploration and optimized performance in less time.

Create detailed hydraulic circuits & actuation systems as part of your multi-disciplinary system simulations, especially for heavy machinery & agricultural equipment, in combination with multi-body systems (Altair MotionSolve®) and granular material systems (Altair EDEM®).

Prepare students for jobs developing mechatronic products through project-based learning. Use hardware kits from Altair's business partner, ACROME, together with no-cost digital twin simulation models and courseware provided by Altair.

Integrate models for mechanical, electrical, and controller subsystems to simulate your mechatronic product holistically as a system-of-systems. Exchange models and/or co-simulate with other CAE tools either from Altair (such as Altair MotionSolve® and Altair Flux®) or from 3rd parties through the Functional Mockup Interface (FMI) open standard.

A mechatronics system consists of mechanical, electrical and control subsystems. Typically, each subsystem is developed and optimized independently. The example of an upright scooter illustrates the benefits of developing a mechatronics product with system integration present from early stages of development. Early on awareness of the behavior of other subsystems together with deep integration later, during the design exploration and optimization stage, highlight the importance of easy subsystem fidelity selection.

The presentation outlines a solution strategy for how a digital twin of a milling machine is solving mechatronic challenges. To improve cycle times, accuracy, and addressing vibration problems a holistic system simulation serves as the basis for optimization. The efficient modeling of the real system behavior with flexibilities, contacts, gaps, friction, nonlinearities in the drives (incl. saturation effects of motors), power electronics in combination with the control system is the basis for efficient controller design and optimization of the control parameters. The dynamic interaction of multiple system components combining 3D finite elements analysis multi-body dynamics and control system helps avoiding Tracking-, drag-, positioning errors rebound, and accumulation effects.  

Presentation by Andy Dyer, Senior Tech Specialist at Altair.

In this presentation, we'll take a look at a few examples of e-Mobility systems models built with Altair Activate and Compose and integrated with other tools like Flux, for electromagnetic simulation for electrical machines (motor/generators), for the purpose of simulating power electronics and motor thermal behavior. We'll also take a look at integrating system model via third-party software like CarSim via the use of the Functional Mock-up Interface, which opens the door to a multitude of tools for further system integration, including packages like MapleSim and DSHplus in the Altair Partner Alliance.
