"Adams/Car was instrumental to tune all subsystems at their best before any real prototype was available… Testing several configurations on the virtual prototype required a matter of hours; doing the same on the real prototype would have been impossible”
Dr. Peter Tutzer, Bugatti

Adams/Car 응용 제품군:

  • Adams/Car
    • Explore the performance of your design and refine your design before building and testing a physical prototype
    • Analyze design changes much faster and at a lower cost than physical prototype testing would require
    • Vary the kinds of analyses faster and more easily
    • Work in a more secure environment without the fear of losing data from instrument failure or losing testing time because of poor weather conditions
    • Run analyses and what-if scenarios without the dangers associated with physical testing
    • Perform a repeatable set of tests on a global basis, ensuring that you work with common data, tests, and, most important, results
  • Adams/Car Ride
    • Model and simulate the ride quality of ground vehicles
    • Create Adams/Car assemblies of suspensions and full vehicles
    • Analyze model to understand their performance and behavior
    • Use modeling elements important for ride quality as in Adams/Car models
    • Analyze the modeling elements independently from other systems using a modeling element test rig
    • Use four-post test rig to support a variety of time-domain analyses
  • Adams/Car Truck
    • Apply component, suspension and full-vehicle templates specifically for heavy truck and bus
    • Model multi-axle, multi-subsystem assemblies that are common in the trucking industry
    • Perform component, subsystem, and full-vehicle analyses in one single environment
    • Explore multiple what if design scenarios with the template-based parametric modeling approach
    • Animate vehicle or subsystem motion onscreen
    • Display graphs of key parameters
    • Produce standardized test reports
  • Adams/Driveline
    • Model and simulate driveline components and study the dynamic behavior of the entire driveline during different operating conditions
    • Explore the interaction between driveline and chassis components, such as suspensions, steering system, brakes, and the vehicle body
    • Apply a specific torque to your driveline model
    • Define a different friction coefficient for different wheels in your model
    • Define a slope of your road to study the performance of your driveline model
    • Alter the driveline geometry and analyze the driveline again to evaluate the effects of the alterations
  • Adams/SmartDriver
    • Bring a vehicle to its dynamic limits or near targets you define
    • Improve handling, durability, or ride performance of the vehicle model based on predicted performance Adams/ SmartDriver computes
    • Investigate system-level dynamics of the vehicle model, while requiring minimal setup
    • Calculate a limit (maximum performance) speed profile over the reference path
    • Check the speed profile using a fast, simplified vehicle model
    • Perform an analysis of vehicle states over the trajectory, searching for path locations that cannot be traveled with the current target speed during the full dynamic simulation
    • Calculate four additional limits using the parameters specified and theoretical limits of the vehicle
    • Creates a speed profile that brings the vehicle to both vehicle limits and user-defined ones
  • Adams/Tire
    • Use with Adams/Car, Adams/Chassis, Adams/Solver, or Adams/View for adding tires to your mechanical model in order to simulate maneuvers such as braking, steering, acceleration, free-rolling, or skidding
    • Model the forces and torques that act on a tire as it moves over roadways or irregular terrain
    • Calculate the forces and moments that tires exert on a vehicle as a result of interaction between the tires and the road surface
    • Apply handling analyses to study vehicle dynamic responses to steering, braking, and throttle inputs
    • Apply ride and comfort analyses to assess the vehicle’s vibrations due to uneven roads with short wavelength obstacles, such as level crossings, grooves, or brick roads
    • Apply 3D contact analyses to generate road load histories and stress and fatigue studies that require component force and acceleration calculation
  • Adams/Chassis
    • Simulate full vehicle events (such as steady state drift, throttle off in turn, and constant radius)
