Designing an Environmentally Friendly Luxury Electric Vehicle with Multiphysics Simulation

Luxury Electric Vehicle

Developing a luxury electric vehicle (EV) from scratch with a short deadline demands organization and access to the right technology to get the job done. Lucid Motors of Menlo Park, California, met the first challenge by putting all the engineers in one room so the structural and aerodynamics engineers would know what the battery, motor and power electronics engineers were doing, right from the start. This collaborative environment has helped them to design a unique automobile with more passenger space by reshaping the battery stack, while optimizing the electric motor, the cooling system, the aerodynamics and the battery life.

How ANSYS Simulation is Helping Virginia Tech Team to Optimize Hyperloop Pod

After placing fourth at the SpaceX Hyperloop Design Weekend in January 2016, as well as the first ever Hyperloop Pod competition in Los Angeles, California, Hyperloop at Virginia Tech is working tirelessly toward improving every aspect of their pod. The Virginia Tech design team comprises over 60 people, branching out to all majors within the university, from business to aerospace engineering. We currently follow a tick-tock engineering cycle, innovating for one competition, then optimizing for the next using ANSYS Simulation. Continue reading

ANSYS Maxwell 18 – Conquer the New Demands of Electromechanical Design and Power Electronics

As you can imagine, there are many conversations at ANSYS centered around the simulation industry and current engineering trends. Sometimes during the conversations with my colleagues that handle the microwave and RF communication and signal and power integrity sectors of our business, I get the feeling that electromechanical design and power electronics is boring. Why do we want to talk about simulation of devices that have been around for a century like electric motors and transformers?   Continue reading

SGI and ANSYS Achieve New World Record in HPC

Looking back at the past couple of years of extraordinary joint engineering projects SGI and ANSYS have undertaken, it is clear to me that when a synergetic hardware and software partnership is established you, our joint customers, are the clear beneficiary. To that end, I would like to walk you through four such examples.

The first example was outlined over a year ago in my ANSYS guest blog, “Solving the Impossible Electromagnetic Simulation with HPC” where with a “grand challenge” benchmark we jointly demonstrated that the SGI® UV platform and ANSYS HFSS software could solve very large, high frequency electromagnetics problems like cosite analysis and radar cross section (RCS) analysis, as well as allow multiple frequency sweeps to be run without running out of computer system memory.

Wireless Power Transfer (WPT)

Wireless power transfer (WPT) is much researched and discussed in the context of IoT, electric vehicles and mobile electronic devices. The methodology of powering a device without a physical connection is well known. However, designing the coil shapes and their placement, maximizing efficiency and validating behavior at the system level still represent challenges that cannot be achieved without simulation. The next frontier to be explored is extending and applying wireless power transfer systems to more applications, such as continuous charging of multiple devices, increasing the range of efficient power transfer and ensuring the WPT system design meets regulatory guidelines.

Advanced Electric Machine Design with Electromagnetic and CFD Simulations

You may have read a quick blog post at Desktop Engineering about ANSYS’s electric machine simulation capabilities. Here we dive into the technical aspects and implications of thermal simulation for electric machines.

Electric machine geometry with cooling and integrated power electronics.

Electric machine geometry with cooling and integrated power electronics.

Modern electric machines are designed to meet a wide range of applications, all facing a variety of different technical challenges. They are designed to be compact with high power densities, to have integrated power electronics, to be high-speed for higher power density, and to handle harsh environments.

These challenges all have thermal implications that affect the lifetime and performance of the electric machine and power electronics, and must be balanced with cost goals. ANSYS simulation tools, Fluent and Maxwell, can be used to predict the thermal and electromagnetic performance of these systems, and can therefore be used to optimize design choices for both thermal and cost considerations while meeting all application objectives.

ANSYS 16.0 Targets Electromechanical and Power Electronic Design

Vehicle electrification, renewable energy, and power delivery applications continue to be major trends driving innovations in the industrial, automotive and aerospace sectors. “Good old designs” of power systems and electrical machines using a build-and-test methodology are out of date. Products using the old approach are filled with inefficiencies, are over-designed, and do not include electronic controls. These applications such as automotive electrification, automotive infotainment, and power electronics across many industries are driving the need for new ways of thinking and new design flows. ANSYS 16.0 delivers! Continue reading

Magnetoelasticity: A 20-Year Journey from Cornell to Michigan Tech to ANSYS INC.

I was reminded of Professor Francis Moon, Joseph C. Ford Professor of Engineering Emeritus, when I visited Cornell University this summer for the 2014 Engineering Development Forum. You see, 20 years earlier I had just completed my PhD dissertation in the area of magnetoelastic buckling, a topic that was initiated by Professor Moon in 1968. His breakthrough research created immense interest around magnetoelasticity in the research community. Continue reading
