LMS International product story

May 8, 2008
With the 1D simulation tools of LMS Imagine.Lab Vehicle Dynamics, development teams can analyse vehicle ride, handling and comfort in the concept stage.
LMS has introduced an extended solution for vehicle handling simulation, offering an integrated solution and engineering services to help vehicle manufactures deliver optimal vehicle handling and to balance the handling performance against other key 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 analyse vehicle ride, handling and comfort in the concept stage for functional specification and functional design, long before detailed CAD or 3D simulation models become available.
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 details.
An advanced interface between both solutions makes it possible to build high-fidelity models of sensors, actuators and active control systems in 1D and seamlessly interface these with 3D mechanical models in LMS Virtual.Lab Vehicle Motion.
With Imagine.Lab Vehicle Dynamics, LMS offers dedicated 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 chassis control strategies.
The solution comes with a large set of dedicated tools for vehicle dynamics engineering, including data management, post-processing and optimisation tools.
The strong integration capabilities of the vehicle dynamics engineering process provide a detailed insight into the numerous 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 the advanced interface with LMS Virtual.Lab Vehicle Motion, engineers can seamlessly interface their 1D control model with 3D component and system models in LMS Virtual.Lab Motion.
This allows 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 modelling and simulation solution to analyse vehicle ride and handling behaviour 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 modelling interface can easily be integrated into a full-vehicle model with a steering system, brakes, powertrain and driveline, electronic control systems and tyres.
Dedicated subsystem templates for suspensions, steering, braking systems and driveline are also provided.
The library of pre-defined vehicle events, including the most common open-loop and closed-loop manoeuvres, can be extended by any user-defined event.
Additionally, the IPG Driver model includes complex driver-vehicle interaction to include human reactions in the dynamic vehicle model.
