OptimumDynamics

OptimumDynamics, is a Computational Vehicle Dynamics program. It is a product based on years of experience in the field of  vehicle simulation and analysis. OptimumDynamics combines an efficient workflow with a flexible and accurate solver. This makes OptimumDynamics the go to tool for any vehicle dynamics problem. The power of OptimumDynamics has been proven in design offices and race tracks all over the world. It has been successfully used in everything ranging from helping a race team to win Le Mans to defining vehicle architectures  for future vehicle platforms.

Overview

Like OptimumKinematics, OptimumDynamics is conveniently divided into three parts: design, simulation and analysis. This makes defining your vehicle, setting up your simulations and understanding your results a simple and easy task. In addition to the extensive documentation, help file and tutorials, OptimumG engineers are also on stand-by for any support questions. We are here to help you get started and get the most out of your simulations.

 

Vehicle Model

Creating a fully defined vehicle simulation model can be a struggle. Perhaps some inputs are unknown or the input data must be formatted in very specific way. With OptimumDynamics you will be running your first simulation within one hour of first starting the software. OptimumDynamics has a modular vehicle modeling system that makes design work easy. You can easily create an initial vehicle model using only basic vehicle data. This can be developed into into a more detailed model once you have additional information and require increased accuracy.   The idea of making it useful before making it complicated can be seen throughout the software.

The vehicle model is made up of multiple parts just like a real vehicle. This includes components such as tires, brakes, springs and coilovers. All components are stored in a library which you can quickly access when building a vehicle. This also makes it easy to share components between setups. Components can be built by bringing in existing data such as bump rubber stiffness values or aerodynamic maps. This can be done quickly thanks to the data import wizards that will work with most data formats. If you have to import data in the same format multiple times then you can easily save import templates to speed up the process.

Adjustable anti-roll bars? Keep all different configurations in the component library and quickly access them for a simulation.

Simulations

Quickly assemble a vehicle setup by selecting components from your library and see the car being built in rich 3D visualizations. Avoid having to go through complicated menus to change a vehicle parameter, instead double-click on the component in 3D and directly edit the component.

Bring in track data to understand how the vehicle behaves in real life situations. Get a deeper understanding of the vehicle by sweeping individual parameters such as lateral acceleration or speed. The quasi-steady state solver in OptimumDynamics uses multi-threading to take advantage of modern computer CPUs for improved simulation speed.

Different designs and setups can be evaluated from different perspectives:

  • Investigate weight transfer
  • Predict ride heights and chassis movements
  • Import logged data to replay laps and correlate with measured data
  • Optimize setups with lap time simulation (coming soon)
  • Evaluate and optimize handling characteristics such as balance and stability (coming soon)

Want to know what the load is on each tire in the middle of a corner but don’t have load sensors? Run a simulation and extend your logged channels with accurate calculations from OptimumDynamics.

Analysis

A key factor to benefiting from vehicle simulation is being able to quickly understand the results. The built in analysis and visualization tools in OptimumDynamics allows you to start investigating the results within seconds of completing a simulation. Drawing on OptimumG’s data processing and visualization know-how, OptimumDynamics makes it quick to understand trends and deviations in the data. For the advanced user the many graphing options can be used to tailor graphs to your specific needs.

Versatility

OptimumDynamics uses a unified vehicle model for all types of simulations and studies. Find the version that matches your need and upgrade as needed.
