Testing

Testing vehicles and their sub-systems is an excellent way to characterize their behaviors. OptimumG holds vast experience in vehicle dynamics testing, both in controlled laboratory environments and out on real road surfaces.

To ensure successful testing, OptimumG engineers consider many different factors when designing tests procedures. Well-designed test procedures are all about relevant test conditions, good test repeatability, and data quality. With proper preparation and planning, physical testing is a competitive option to simulation.

OptimumG works with world-class laboratories and equipment all around the world. We deal directly with the testing facilities and ensure that costly mistakes are avoided, partly with thorough preparation and partly by real-time monitoring and analysis of tests and collected data.

Allowing OptimumG to help organize and execute your tests means that the test will be run as efficiently as possible. Rather than receiving a set of raw data, which is the norm with most test providers, OptimumG will analyze and interpret the results for you. In addition to hard numbers, OptimumG will put the results into perspective through analysis, visualization, and conclusions. OptimumG provides the facts that will help you arrive at the best decision.

Past testing projects have included:

Tire Testing and Modeling

Having access to accurate tire data and tire models is extremely important in vehicle dynamics development. OptimumG helps customers collect and post-process tire data from tire testing machines. OptimumG provides modelling services to convert raw data into tire models that can be used in vehicle dynamic simulations. Using these models, OptimumG also helps customers  make sense of these results to aid decision making.

On-track testing and vehicle characterization

On-track vehicle testing can present a challenge, and whether it’s about understanding or developing your own vehicle or benchmarking the competition, OptimumG can help plan, execute, and evaluate on-track tests. For other types of tests such as torsional stiffness, center of gravity height, and moment of inertia tests, OptimumG can advise on methodology and help ensure that measurements are valid.

Vehicle Characterization (Moment of Inertia testing)

Vehicle instrumentation

OptimumG helps clients select, design, install, and calibrate data acquisition hardware to vehicles and other test equipment. OptimumG ‘s assistance ensures that the most cost-effective solution is implemented, while maintaining measurement and durability requirements.

OptimumG install data acquisition computers and sensors, connected with appropriate wiring and connectors.

Wind tunnel testing (scale, full-scale, fixed and rolling road)

Efficient aerodynamics are important both on the road and on the racetrack. OptimumG contributes to the planning, execution, and analysis of wind tunnel tests. Combined with our experience working with CFD, OptimumG can advise on the best approach for aerodynamics testing and development.

K&C testing

Testing your vehicle on a K&C (kinematics and compliance) rig , can provide insight into factors that influence ride and handling that can be difficult to see in simulation or find with on-track testing.

Powertrain testing

Although much of a car’s ride and handling characteristics are attributed to the chassis and tires, the powertrain also plays an important role. OptimumG work with customers to understand how different powertrain behaviours influence ride and handling.

Engine power and efficiency has an impact on ride and handling.

7-post rig testing

The transient response of any vehicle is closely related to damping characteristics of the vehicle. Testing on four,seven, or eight-post  rigs is a powerful tool in tuning the  damping and stiffness settings of any vehicle. OptimumG has experience with shaker rig development for many types of vehicles. Whether it’s about ride quality, tire load variation, or platform control, OptimumG has the tools and savvy to help determine settings.

Component testing (damper, spring, antiroll bar, bump stops, bushings, etc.)

Testing individual components serves as a cost-effective way to understand how individual components influence overall ride and handling characteristics. OptimumG can advise on these types of tests.

Design of experiments and test design, test planning, and test management

To ensure successful testing, OptimumG engineers consider many different factors when designing tests procedures. Well-designed test procedures focus on relevant test conditions, good test repeatability, and data quality. During tests, OptimumG engineers continuously monitor results to confirm data quality. This means that tests can be re-run instantly, and we can perform changes in test procedures should the situation require it, saving both time and money, as there will be no need for later re-tests.  

Test data post-processing and visualization

After most types of testing, large amount of data need to be collected. Going through this data can prove very time consuming. OptimumG has post-processing routines for most types of tests. This means that OptimumG engineers  can process large amount of data efficiently and highlight important areas. Once the processing is complete, different types of visualization are utilized to communicate the results.

Test data and simulation correlation and validation

Testing results aren’t always perfect, and the same can be said about simulation results. OptimumG can help clients comprehend differences between simulation and testing using different correlation and validation techniques.
