Overcoming Electric Vehicle Challenges: Aerodynamics

Vehicle manufacturers are facing challenges on all sides. Electric and autonomous vehicles intensify the challenge, bringing big opportunities to experiment with form but also increased risk, as designers don’t yet have tried and trusted data to tell them what has worked in the past. In addition, customers expect the experience of driving any new car to match the promises of its eye-catching style. Trade-offs between looks and performance are no longer acceptable and to avoid them, manufacturers need a rapid, robust process that brings styling and engineering together from the start.


In the automotive market, one race is toward the electrification of vehicles. Several major automobile manufacturers already offer electric cars, including TeslaKiaBMWNissanChevroletFord, and Volkswagen but we are also seeing a rise in new players, and start-up businesses who are coming to the market with viable products.

This pressure is leaving manufacturers with a sense of urgency to develop their own electric vehicles to keep up with their competitors and satisfy the needs of a growing number of customers who want to drive vehicles that make less of a negative impact on the environment. Can simulation help?

During our ‘Overcoming Electric Vehicle Challenges’ series, we will be exploring various challenges faced by manufacturers looking to pioneer electric and autonomous vehicle technology. In this article, we will be focusing on Aerodynamics.


Why is Aerodynamic Performance so crucial to the success of Electric Vehicles?

One of the biggest challenges for Electric Vehicle manufacturers is the issue of range or lack thereof in comparison to traditional combustion engine cars. Since the issue of range anxiety holds back many potential buyers, aerodynamics plays a crucial role in the success of electric vehicles – The more streamlined the car, the longer the range for the same battery.

Every kWh/m of energy consumption that can be shaved makes the car cheaper to manufacture, lighter, and more efficient. This is because the vehicle will require less battery cells to go the same distance, therefore reducing battery weight, and resulting in a lower rolling resistance

How can Simulation support Electric Vehicle Aerodynamic Performance?

Simulation allows designers and engineers to create and test virtual models of vehicles while avoiding the time and cost of building multiple physical prototypes. In general, simulation enables the final product to be built faster, to higher engineering standards, while reducing costs. This is especially important in a crowded automotive market where manufacturers are under pressure to expand their range and offer custom configurations. When it comes to those radical ideas for new EV designs, having simulation tools to give feedback on how untried vehicle shapes will perform is essential to move the industry forward.

Electrification and autonomy are two of the most important emerging technologies that are leading the automotive industry revolution. This revolution has been made possible by the ability to digitally simulate, study, and improve vehicle aerodynamics, helping engineers to uncover new ways to improve efficiencies, save energy, and boost range.

This on-demand webinar will describe the process of setting up and analyzing a DesignGUIDE design study, as well as cover a series of examples across different industries and disciplines.
On-Demand Webinar
Duration: 45 Minutes


Manufacturers developing vehicles and products must innovate in response to rapid industry transformations, satisfy heightening consumer expectations, and meet all cost, quality, and regulatory requirements on time. 

Integrating simulation in the development process is critical to successfully meeting performance targets. However, traditional simulation results analysis generally does not directly indicate what design changes to make to improve performance. In addition, design decisions can be primarily driven and constrained by aesthetics, not only performance. Finally, the performance objectives of different engineering teams are often in conflict. 

These challenges inevitably lead to suboptimal design decisions, missed performance targets, and development delays.

To respond to these challenges, the PowerFLOW 2020 release introduced DesignGUIDE, a brand-new capability that enables manufacturers to interactively explore the impact of design changes on performance. With DesignGUIDE, manufacturers can acquire intuitive design guidance to achieve both engineering performance targets and design requirements.

Watch this e-seminar to find out how you can leverage DesignGUIDE to:

  • Directly connect design to performance KPI’s
  • Make accurate, data-driven design decisions
  • Collaborate with designers
  • Account for multi-objective trade-offs

Key Highlights: 

  • Integrated analysis of geometry changes and performance
  • Simulation-based design guidance is provided with a color map
  • Interactive design review environment
  • Multi-objective support across engineering disciplines

Adaptive’s Cynde Murphy to Speak at V&V Symposium

V&V Verification and Validation Symposium
Conference May 15-17
Training & Committee Meetings May 13-14
Westgate Resorts, Las Vegas, Nevada

Dynamic Load and Weld Fatigue Calculation for Validation of a Telescoping Boom Chassis presented by:

Adaptive’s Cynde Murphy, Simulation and Services Manager
Bob LeGrande, Engineer Principal III, Terex Corp., AWP Division – Genie Industries
Kyle Roark, Engineer Principal II, Terex Corp, AWP Division – Genie Industries

Analytical simulation is a powerful tool that can allow for understanding the dynamic behavior and fatigue life of any structure. However, one of the most challenging tasks involved with developing a simulation is developing accurate and realistic load cases, which replicate field strains in the structure, so that it may be used for validation. Once a representative finite element model (FEM) of a structure is created, challenges arise when understanding and applying dynamic loads to the FEM so that correlation and validation with physical testing is accurate. One step further in complexity is being able to calculate dynamic stress profiles for the entire structure, and use those results for further investigation, in this case fatigue estimates.

Historically, analysts have had to rely on expensive prototyping and time-consuming full vehicle measurements, even within the iterations of one design concept. Analyze-Build-Test is quickly becoming a thing of the past, as product development companies strive for quick to market designs. Simulation experts at Adaptive Corporation, in conjunction with Terex, were able to circumvent this traditionally laborious process and develop an efficient and accurate validation process. Our team has leveraged the use of ANSA, ABAQUS, Wolf Star Technologies True-Load™ software and Fe-Safe, to develop an FEM, understand the dynamic mechanical loads and develop a duty cycle for the Terex telescoping boom chassis. This body of work can and will be subsequently used for design, simulation, fatigue analysis, validation and engineering development of iterations of the same chassis structure, as well as similar chassis designs.

The general steps of the process are as follows: FEM Creation of Assembly FEM of the chassis structure was created using ANSA pre-processor software. Instrumentation and Data Acquisition To successfully calculate mechanical loads acting on the Terex Telescoping Boom Chassis for the FEM, accurate strain measurements were required. Using the FEM and the Wolf Star Technologies True-Load™ software, optimal strain gages placement was identified and installed on a test chassis. Strain gage time history data for various proving ground events, such as cornering, washboard, curbs and potholes. Load Calculation and Development Using the time history data for the optimal map of strain gages, the FEM and True-Load™ software, equivalent (dynamic) unit loads were calculated. Fatigue Analysis Using dynamic stress results from the FEM, given a duty cycle that included a combination of various proving ground events, fatigue life estimates of the Terex Telescoping Boom Chassis and critical welds were calculated. Calculating the mechanical loads for this project allows Terex the ability to rapidly iterate on designs for this chassis, as well as provide a starting point for other similar chassis designs. This ultimately saves time and money in their product development cycle by reducing the efforts of traditional design-build-test cycle, by means of “virtual validation.”
