Suggested Strategy for Getting Started
• Getting Started Tutorials:– Work through the tutorials accessible via the online
help, especially Getting Started with Adams/Chassis• Use Example Database as-is:
– Add/register example database– Open suspension assembly or full vehicle assembly
also called as vehicle configuration file– Perform simulation maneuvers of interest to you to get
familiar with these example vehicle models• Customize example database models:
– Modify the subsystem and/or assemblies to match yourvehicle setup.
– Perform simulation maneuvers of interest to you withyour own vehicle models
