Analysis

Fully understanding the behavior of a vehicle dynamics system and its interaction with other systems can be a challenging task. OptimumG analysts can help increase your understanding of the characteristics and performance of any vehicle dynamics system. Our analyses and conclusions will help you make the most informed decision, whether it pertains to vehicle design/setup or product strategy.

Thanks to our highly scalable analysis tools and methods, we can deliver accurate analyses very quickly or spend a little more time and deliver very accurate analyses depending on your needs. Our approach for any analysis task is to start with the most straightforward analysis tool, and then, we  increase the level of complexity until we reach conclusive results. This ensures that we always use the most cost and time-effective approach to solve your problems.

In most cases, we use testing or simulation results to fully understand the ins and outs of a vehicle or vehicle sub-system. We utilize different types of simulation tools in cases where a vehicle/sub-system has not been built or where testing is not deemed cost-effective. In other cases, testing provides the most helpful data that will allow us to obtain beneficial results.

After concluding an analysis project, our analyst will report on our findings and offer our recommendations. Most analysis projects are discussed within the entire engineering group at OptimumG; this means that our engineers, with a wide range of past experiences, get to voice their view on the problem and possible solutions. Often, we have an open dialogue during which we share our ideas and suggestions for solutions and future work with the customer.

If you would like to contact a project manager to discuss an analysis project, please contact us.

Past analysis projects include:

Vehicle concept study

OptimumG helps customers evaluating vehicles even before they are built. Through simulation and calculations, OptimumG can help define important vehicle parameters already in the planning stage. Setting these specifications ensures desirable vehicle dynamics performance when the vehicle is driven for the first time. These studies can vary from very crude estimations  to detailed specifications that are used to drive the detailed design process.

Suspension kinematics optimization

OptimumG’s experienced suspension engineers help customers find kinematic solutions that match the needs of the vehicle. Important parameters such as roll-center, camber variation, bump steer, and more are covered. Projects can range from fully optimized designs for a given vehicle or “sanity checks” of existing designs.

Suspension design analysis (kinematics/dynamics/mechanics)

Through its consulting projects, OptimumG has seen most types of suspension layouts. Backed by this experience, OptimumG can advise on any aspect of the suspension design. We can avoid costly mistakes and determine methods to increase performance while the design still is on the drawing board. Existing designs can also be evaluated to improve performance or solve issues.

Track performance studies

Through data analysis and simulation, OptimumG can aid clients in understanding the desired vehicle setup for a given track. Factors such as tire and brake wear and fuel consumption can be accurately predicted, which then can be used to design a race strategy. We can examine optimal settings for parameters such aerodynamic configurations and gearbox ratios and also recommend chassis setups based on vehicle balance and driver style for a given track.

Tire

Matching a tire to a vehicle or a vehicle to a tire is difficult. Thanks to OptimumG’s experience in working with both tire manufacturers and vehicle manufacturers/race teams, OptimumG engineers can link tire characteristics to vehicle characteristics. This means that OptimumG can advise tire manufacturers on desirable tire characteristics for a given vehicle or a vehicle manufacturer/race team on which tire characteristics their vehicle needs. OptimumG relies on a set of proven tools and methods to help the client find the best tire for a given vehicle.

Vehicle setup analysis

Sometimes a vehicle doesn’t perform as well as desired. OptimumG can analyze vehicle setups and find the areas in need of improvement to increase performance and solve issues. In past projects, OptimumG has been able to identify changes to sets of parameters that have been overseen by the client. Most often, these changes have lead to noticeable improved performance as motorsport customers have gone from placing in the middle of the pack to qualifying on the pole.

Race track layout analysis

Previously, OptimumG has helped multiple racetrack facilities to evaluate racetrack designs before they’ve been built. Through simulation, OptimumG is able to provide lap time and speed estimations for different track layouts and configurations. Typically, this is used by the track designer to correct dimension run-off areas and other safety features. OptimumG can also provide key metrics regarding the track and how it compares to other tracks around the world; this can help to describe the “feel” of the track in early design stages.

Aerodynamics data analysis

OptimumG has experience working with aerodynamics data collected from windtunnel testing, CFD simulations, and on-track testing. From this type of data, OptimumG can construct aeromaps that can be used in vehicle simulations and analysis. OptimumG can make recommendations on chassis setup to use the aerodynamics to its fullest using this data. We can also recommend desirable aerodynamic characteristics to ensure efficient, stable, and well-balanced vehicle dynamics behavior.

Race team operations analysis

Because of experience working with a multitude of different race teams, OptimumG has the experience to identify good and poor practices in the operations of a race team. After a team visit and accompanying the team to test and/or race, OptimumG can suggest changes to improve team performance. The study covers areas such as operations management, information management, personnel and time management, and race engineering methodologies and workflows.

Driver characterization

OptimumG’s data engineers can quickly characterize driver styles through the use of logged data, video recordings, and driver debriefing. This information can be implemented to help the driver improve his/her techniques and style. It can also be used to help the engineer design vehicle setups that closely adheres to the specific driver’s driving style.
