3D Vehicle Mechanics

3D Vehicle Mechanics

In order to ensure an optimal design for rider comfort, GT-SUITE offers a detailed solution for evaluating high fidelity vehicle dynamics and handling. A rich library of customized control, mechanical and hydraulic model-based components empowers users to create an advanced vehicle model including subsystems in order to assess their interaction at higher stages of development and/or validation. All subsystem models can be easily interchanged within the GT-SUITE platform. Predictive powertrain models are generated and integrated with a vehicle plant model by combining a dedicated tire characterization with other GT-SUITE comprehensive template libraries, such as engine and transmission. By capturing excitations from both the road and the powertrain altogether, these models are used to perform accurate and efficient vehicle dynamics and driveline noise, vibration and harshness (NVH) evaluations.
