"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)

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
