ADAMS/Tire COMPREHENSIVE TIRE MODELING, SIMULATION, AND DATA ACQUISITION SERVICES MSC.Software and the Road Vehicles Research Institute of TNO – an independent applied science research organization based in the Netherlands – have joined forces to provide global automotive companies with the most comprehensive set of tire modeling and simulation software and tire data acquisition services available today. These tools allow advanced application of virtual prototyping technology in assessing the effects of tire-roadway interaction on full-vehicle performance without extensive hardware testing. Tire testing and data fitting services are available to your organization through TNO and Smithers Scientific Services, Inc. PRODUCT MSC.ADAMS Industry–Specific Product The ADAMS/Tire module lets you easily model the forces and torques acting on a tire moving down a roadway or over irregular terrain. Used in conjunction with other specialized MSC.ADAMS vehicle simulation software, you can simulate large-displacement dynamic vehicle behavior during any maneuver, including those involving braking, steering, acceleration, free-rolling, or skidding. You can select from among six tire models for performing vehicle handling studies, based on your product design and testing requirements. ADAMS/Tire models accept input data ranging from simple tire characteristics – used, for example, with the Fiala and University of Arizona models – to extensive and detailed tabular tire test results utilized in the Smithers model and the Delft (Pacejka “Magic Formula”) model. The “Magic Formula,” widely recognized for its accuracy, is based on published empirical tire data-fitting routines developed by Professor Hans Pacejka at the Netherlands’ Delft University of Technology in cooperation with Volvo Car of Sweden. This model converts massive amounts of tire data into a manageable set of parameters to define the tire’s physical characteristics for roadway simulations.

TIRE MODELS
(1) The General Data Method computes vertical force using the tire penetration and penetration rate on a 3D discrete triangular surface.(2) The Point Follower Method computes vertical force using the tire penetration and penetration rate on a 2D surface.(3) The Equivalent Plane Method estimates an area equivalent to the area of deformation and uses the estimated area to compute the vertical force.
CAPABILITIES
Easily Explore “What-if” Scenarios
Rather than rely on guesswork or time-consuming physical testing,you can use ADAMS/Tire’s models to perform “what-if” analysesaimed at finding the optimal tire-vehicle configurations.You can easily swap tire data to immediately see the effects onvehicle performance. You can also test different tire data at different
wheel locations, in case wheel positions can vary in your vehicledesign.
Optimize Tire-Vehicle Performance
Tire modeling with ADAMS/Tire can range from simple tosophisticated. For example, the Fiala model is easy to work with and
runs fast. Using estimated data for several key tire parameters, youcan quickly get your vehicle model up and running. For advancedapplications, both the Smithers and Delft models use highlyaccurate data-fitting routines on a broad range of tire parameters.This helps you get accurate visualization of handling behavior andallows easy refinement of your tire or vehicle model. Also, with theDelft model, you can set scale factors on a given tire, enabling youto perform parameter studies to determine your vehicle design’ssensitivity to variations in tire performance.
