Improving Speed and Precision of a CNC Milling Machine with Holistic System Simulation

Altair HyperWorks' Design Explorer is an end-to-end workflow for real time performance prediction and evaluation.

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®).

Connect your product-level system simulations to your product's functional requirements (e.g., coming from SysML via Model Center MBSE-Pak) such that your system model serves as your Authoritative Source of Truth (AST) for your virtual product development activity.

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.

Many engineering projects start with CAD geometries. In order to perform design exploration studies and optimization on CAD-based FE models, an automated process is required including CAD, Preprocessor, Solver and Design exploration tools. This example presents a solution to implement CAD tools into an automated simulation-driven design exploration and optimization process.

Due to the large scale nature of Architectural, Engineering & Construction projects, frequent change orders, and on-time delivery pressure, more often than not the ability to use traditional simulation methods for design guidance and validation is simply time and resource prohibitive.

In this video EDEM is coupled with MotionSolve to accurately predict the performance of an off-road buggy on different terrains. With EDEM, an extensive range of terrains can be modeled to suit the vehicle test requirements, including sand, gravel or soft soils. The coupling enables engineers to validate the system dynamics under realistic operating conditions. Additionally, analysis on the vehicle component’s performance and the terrain can be conducted to fully understand the test results.

Watch examples of applications of EDEM coupled with MotionSolve and Activate in the design of tracked and wheeled vehicles.

EDEM software, powered by the Discrete Element Method (DEM), accurately represents the behavior or rocks, soils and ores and can realistically model a variety of terrains from soft-soil, dry sand, to rugged gravel surfaces. Integrating EDEM with Multi-body Dynamics tools provides great realism in vehicle mobility simulations and enable engineers to predict the behavior and performance of off-road vehicles in a variety of off-road environments and to study complex manoeuvres which otherwise might be restricted.

EDEM, MotionSolve and Activate are used to assess the performance of a 8x8 light armored vehicle (LAV) and to perform stress validation.

EDEM, MotionSolve and Activate are used to predict the behavior and performance of a tank vehicle on a sand dune and to study complex maneuvers live a pivot turn.

Altair Flux offers faster and more accurate 3D magnetostatics analysis thanks to the implementation of new integral method. This is extremely interesting for applications with a lot of flux leakage in air, such as sensors modelling. No air mesh is required, dramatically reducing the computation time versus classical finite element method and offering much higher accuracy.

Altair model-based development tools drive fast development for smarter connected systems. Altair customers simulate complex products as systems-of-systems throughout their entire development cycle. Explore more by combining mechanical models with electrical models to enable multi-disciplinary simulation and leverage automatic code-generation for your next generation embedded systems.

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.
