Helping you design and create machines is what drives us. Our mission is to continue advancing engineering software you need in order to make exceptional products.
The main purpose of the Users Conference is to allow participants to exchange technology, and we would like it to be a place where everyone is brought closer together to share the vision of a brighter future for device manufacturing.
We hope you enjoy the exhibitions and technical discussions by JMAG’s technical partners.
RT-LAB is the real-time simulator, developed by OPAL-RT.
We can use RT-LAB with JMAG-RT, to have more accurate results.
Torsional Vibration Analysis of an electric-drive powertrain via system simulations with Simcenter Amesim and JMAG-RT
Modeling and simulation of Torsional Vibration Analysis of electric drive is largely done using a suit of 3D simulation tools. However, for some aspects, system simulation can support and provide answers quickly and efficiently. In this talk we will present the 1D Simcenter Amesim, a multi-physic simulation tool, in combination with JMAG-RT to address relevant use case of the TVA of an electric drive.
As electric vehicles become increasingly more mainstream, an increasing level of refinement is required for a modern driving experience. As efficiency and NVH targets become increasingly more stringent, an integrated CAE modeling approach is required to predict system behavior early in the development cycle. This integrated CAE approach requires multi-disciplinary modeling, of electromagnetics, mechanics, and thermal systems together. While these analyses may typically be managed by different engineers, or even different departments, there is a growing need for increased collaboration. This presentation will detail several avenues for increased collaboration of motor integration to improve NVH behavior.
In recent years, from the viewpoint of motors downsizing, as the motor drive frequency increases, it has become necessary to reduce iron loss in the high frequency range and improve magnetic flux density in electrical steel sheets used as core materials.
Therefore, we have developed a new Si gradient steel “JNRF”. In this presentation, we will report the results of motor efficiency analysis when a new material “JNRF” is applied to the IPM motor.
Supercomputer Fugaku jointly developed by RIKEN and Fujitsu
ranked No.1 again in four HPC performance ranking in November 2020.
Using the same Arm based A64FX CPU as Fugaku,
FUJITSU Supercomputer PRIMEHPC FX1000 is high-performance, highly scalable yet very reliable supercomputer for extremely large-scale systems
and FUJITSU Supercomputer PRIMEHPC FX700 is an easily deployed model in the PRIMEHPC series based on standard technology
We also introduce the status of porting activities of JMAG on FX1000 and the plan of evaluating JMAG on Fugaku, which we are currently collaborating with JSOL.
dSPACE SCALEXIO HIL simulator and E-Drive solution are introduced in this session.
HILS(Hardware In the Loop Simulation) is a must for the vehicle development process. High accuracy and high performance are required for E-Drive HILS plant models. Various models for motors, inverters and sensors are required. Ones for application specific electrical circuits are also required in some cases. dSPACE E-drive HILS solution including the real time JMAG model is available for such user needs.
Recent update of electric machine thermal management with CFD How to employ the oil cooling method (pros and cons)
Electromagnetic analysis by JMAG is recently getting improved at speed and accuracy.
To apply such results to the multiphysics simulation, those, of course, should be high fidelity.
For instance, if JMAG gets detailed loss distribution, the thermal analysis should build a detailed cooling methodology.
This seminar will present the recent CFD analysis updates for motor thermal management with oil cooling presented by siemens at the JMAG user conference 2018.
Recently, it has become common to use electromagnetic field analysis in the design of electrical equipment to reduce the development time of products with fewer prototypes.
However, many JMAG-Designer users are suffering from a lack of “effective utilization technique of electromagnetic field analysis”, like due to a poor understanding of the underlying physical phenomena.
In this seminar, we will introduce the IDAJ electromagnetic field analysis service by explaining examples for various applications.
Recently due to the market expansion of EV, more efficient motor gearbox design process is desirable. For identifying noise issues early in the design stage, it is necessary to consider interactions between gearbox and motor.
A new software interface between JMAG and Romax software has been developed to simplify the data transfer between electromagnetic and NVH analysis as part of an end-to-end analysis process.
In recent years, the use of motors has been increasing in many industries including the automobile industry.
The primary purpose of CAE for motors is to pursue efficiency, but in order to evaluate performance, it is necessary to solve the problems of heat and noise. These problems can be solved by linking JMAG, and MSC Software’s thermo-fluid analysis software scFlow and acoustic analysis software Actran. Introducing examples of collaboration between JMAG and scFlow, and JMAG and Actran.
Ultra-high fidelity Hardware in the Loop (HIL) Simulation for EV motor Drives with seamless integration with JMAG-RT
In this talk we will demonstrate Typhoon HIL’s ultra-high fidelity power electronics and motor drive Hardware in the Loop (HIL) solution, including vertically integrated hardware and software, with seamless integration with JMAG RT machine models. We will demonstrate a typical
workflow for the design, testing, and verification of Electric Vehicle (EV) drive train starting with JMAG FEA motor design, followed by seamless export of ultra-high fidelity spatial-harmonic Permanent Magnet Synchronous Machine (PMSM) motor model from JMAG-RT into Typhoon HIL
simulation environment. After demonstrating complete Software in the Loop (SIL) simulation capability we will demonstrate one-click export of the model into the Controller Hardware in the Loop (C-HIL) real-time simulation performed in the HIL404 simulator, Typhoon HIL’s latest 4th generation HIL platform interfaced with a real Engine Control Unit (ECU) in the loop. In addtion, we will showcase HIL interface towards the test automation software and also show XIL ASAM compliant API functions.
RecurDyn/DriveTrain provides easy modeling configuration of gears, bearings and shafts using KISSsoft interface and analyzes dynamic behaviors of various kinds of drive systems. A gear box model is created in RecurDyn pre/post, and dynamic simulation is implemented with RecurDyn solver.
In this paper, a typical process of simulation is introduced to analyze an entire system of drivetrain.
And, it also verifies the interaction between RecurDyn and JMAG-RTT where an electric motor model gives a driving system an effect of excitation for more accurate results of vibration and resonance both in time and frequency domains.
