Battery & Motor Thermal Management for Electric Vehicles
The key element of an electric vehicle (EV) is the battery and batteries are known to produce heat during their charge-discharge cycle. An efficient thermal management system (TMS) is of paramount importance. The battery TMS affects the cost, life, and range of the EV. A battery TMS study or an EV TMS study involves the use of thermal and fluid physics and Altair’s AcuSolve (Computational Fluid Dynamics based Simulation Technology), was used to carry out this study. The importance of finding new methods for effectively and accurately designing TMS that control temperature and optimize the performance of Li-ion batteries. This can be used to study and optimize the Battery Thermal Management System and other Thermal Management requirements arising in an electric vehicle which involves both active and passive cooling. A similar issue of heat (unwanted) exists in Motors as well, in this, we shall cover the Multiphysics simulation of Motors which shall include both electromagnetics and CFD Thermal studies of both air and liquid coolant motors.

NVH Refinement for Electric Vehicles
Replacement of traditional combustion engines with an electric powertrain, bring electro-mechanical induced tonal and high-frequency whine noise. In addition, tire and aerodynamic turbulent noise become more prominent in the absence of a standard Internal Combustion Engine. Also, the perceived sound quality imposes a new set of challenges. This leads to completely new methods of NVH refinement, keeping the decades of research aside. As it is important to address these issues at the design and development stage, adopting the new simulation techniques to manage future NVH challenges in e-Mobility is of the prime challenge to the traditional NVH engineers. In this webinar, we shall discuss some of those key NVH challenges specific to electric vehicles and appropriate simulation processes to develop countermeasures.

Magneto Vibro Acoustic Design of PWM Fed Induction Machines
Induction Motors (IM) are widely used in various industries. To ensure their speed control, IM will be supplied with pulse width modulation (PWM). This kind of supply, can impact efficiency of the motor and degrade its vibro-acoustic behavior, generating noise nuisance. To tackle these technical challenges and ensure best-in class acoustic comfort for users, it is necessary to design a quiet e-motors at the early stage of design.
The first aim of this paper is to show a new method to reduce noise and vibration due to PWM supply of induction machine. The proposed approach allows the passive reduction of air-gap flux density harmonics in an induction machine. The second interest, is to show a new method to analyze the vibro-acoustic behavior of a PWM-fed IM. The method is fully finite element (FE) computation. Finally, the third interest of this article, is to compare noise and vibration results between the proposed FE method, magneto-vibro-acoustic coupling and measurements. Good agreement between measurements and computation will be shown.

    Mode tracking and rotor energy from complex eigen value analysis with OptiStruct.

    Topic Detail
    Mode Tracking is now available for rotor dynamics with complex eigenvalue analysis
    • It is mapping the mode-shapes of a system from one state to another.
    • Tracking is carried out using various methods shown in the below bulk card.
    • Assumption is that the two states are close for eigenvectors to retain orthogonality across states.
    • Mode-tracking in rotor dynamics tracks modes across rotor speeds and yields a much better Campbell diagram, as shown below.

    OptiStruct – Key Performance Indicator Output



    Product Version: OptiStruct 2018.0 or above

    Topic Objective
    Key performance indicator output in OptiStruct.

    Topic Detail
    KPI (Key Performance Indicator)
    • OUTPUT,KPI or DISP(KPI) .kpi ascii file is output
    • Currently supported for linear and nonlinear static analysis
    • Max value for displacement/stress/strain/plastic strain based on groups by property
    • Stresses and strains are supported for shells and solids

    KPI output filtered for user specified property (Available with V 2019.1)
    • KPI output is limited to the grids/elements within the output sets. Set of property could be used to request the KPI output only for a list of properties.

    Digital Power - Simulation Blockset overview
    Brief overview of the simulation blockset of the Digital Power Designer. In this video we look into and analyze a selection of bocks used for simulation (Compensators, PWM simulation, Voltage Mode Control simulation, Buck Converter).


    Digital Power - Coefficient Conversion
    Select/tune the coefficients of a PID compensator. Users can calculate the digital coefficients from the analog component values or can tune the coefficients on the fly.
