LMS Integrates 1D and 3D Simulation for Vehicle Handling

6 May, 2008

Extended simulation solution allows manufacturers to combine 1D vehicle-handling analyses with 3D component and systems models.

LMS has introduced an extended solution for vehicle-handling simulation that reportedly can help vehicle manufacturers deliver optimal vehicle handling while balancing handling performance against other attributes in chassis development, including ride comfort, road noise, and durability.

With the 1D simulation tools of LMS Imagine.Lab Vehicle Dynamics, development teams can analyze vehicle ride, handling, and comfort in the early concept stage for functional specification and functional design. As more design details are fixed, 3D models can be developed with LMS Virtual.Lab Vehicle Motion to simulate vehicle handling and ride comfort in more detail. An advanced interface between both solutions makes it possible to build high-fidelity models of sensors, actuators, and active control systems in one dimension and seamlessly interface these with 3D mechanical models in LMS Virtual.Lab Vehicle Motion, the company states.

With Imagine.Lab Vehicle Dynamics, LMS offers 1D simulation tools to design and validate individual chassis subsystems and actuators and to integrate them in a single system model to simulate and validate global control strategies. The solution comes with a range of dedicated tools for vehicle dynamics engineering, including data management, postprocessing, and optimization. Integration capabilities of the vehicle dynamics engineering process provide insight into the component and system interactions that determine a vehicle's ride and handling profile.

With the LMS Imagine.Lab Vehicle Dynamics Control solution, chassis designers and engineers can simulate vehicles, sensors, actuators, and the control strategy in a single comprehensive platform, from which data can be exported into real-time targets for Hardware in the Loop validation. Through interface with LMS Virtual.Lab Vehicle Motion, engineers can combine their 1D control model with 3D component and system models in LMS Virtual.Lab Motion, facilitating a detailed simulation of the real-life interaction of sensors, actuators, and active control systems with chassis and suspension systems.

LMS Virtual.Lab Vehicle Motion offers an integrated 3D modeling and simulation solution to analyze vehicle ride and handling behavior from passenger cars and motor sport vehicles to multiaxle vehicles like trucks and buses. Front and rear-axle suspension models created with the template-based modeling interface can be integrated into a full-vehicle model with a steering system, brakes, powertrain and driveline, electronic control systems, and tires. Dedicated subsystem templates for suspensions, steering, braking systems, and driveline also are provided. A library of predefined vehicle events, including the most common open-loop and closed-loop maneuvers, can be extended by any user-defined event, and the IPG Driver model includes complex driver-vehicle interaction to include human reactions in the dynamic vehicle model.
