Ride and handling

LMS takes full responsibility over ride and handling attribute development, including pre-program benchmarking, target setting, concept development, detailed chassis development, and prototype refinement of suspension and steering system characteristics. LMS Engineering can shape the character of a vehicle by delivering a meticulously balanced combination of handling and ride comfort, while taking road noise into account.

Competitive benchmarking and target setting

Correlation studies between subjective impressions and objective comfort, handling and steering handling measurements, in view of full-vehicle target setting
Cascade full-vehicle targets into targets on the level of individual body, chassis and suspension components for ride comfort, handling and steering handling

Concept development

Develop guidelines for setting up suspension hard points and developing the suspension architecture
Perform elasto-kinematic analysis (assuming rigid parts)
Analysis of full vehicle handling, steering handling and ride-comfort behavior (assuming rigid parts)
Early evaluation of harshness and other ride comfort performances and definition of the global suspension characteristics using simplified models
Fixing tire, suspension and steering system characteristics

Detailed chassis development

Optimizing suspension designs for improved ride and handling performance, including the assessment of comfort maneuvers, obstacle crossing and the response to rough road profiles
Steering shimmy and brake judder analysis and optimization
Analysis of drivability performances such as tip-in/tip-out, engine start, gear shifting
Minimizing torsional vibrations of the driveline
Full flexible elasto-kinematic analysis
Development of active control systems through co-simulation with controllers and power systems, until final validation and tuning
Detailed simulation of vehicle handling, steering handling, ride-comfort and harshness behavior considering body flexibility
Robust design analysis taking into account component characteristic dispersions and/or usage
Robust design analysis taking into account the tolerance position of the hard points of the suspension

Prototype refinement and validation

Refinement of suspension and steering system characteristics based on Test and CAE
Final tuning of the control system
