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”

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)
• Simulate half vehicle events including dynamic load case and static vehicle characteristics
• Use with Adams Insight to perform systematic experiments on vehicle model
• Study the effect of multiple design variations
• Optimize the design
• Address the robustness issue
