ADAMS is a powerful modeling and simulating environment that lets you
build, simulate, refine, and ultimately optimize any mechanical system, from
automobiles and trains to VCRs and backhoes.
Basic ADAMS/Solver training teaches you how to build, simulate, and refine
a mechanical system using Mechanical Dynamics, Inc.’s ADAMS/Solver and
ADAMS/PostProcessor.

■ Build simple ADAMS models.
■ Understand ADAMS product nomenclature and terminology.
■ Understand basic modeling principles.
■ Use the crawl-walk-run approach to virtual prototyping.
■ Debug your models for the most common modeling challenges (for example,
redundant constraints, zero masses, and so on).
■ Use and be informed about all methods of ADAMS product support.
■ Use the product documentation optimally.

This guide is organized into modules that get progressively more complex. Each module
focuses on solving an engineering-based problem and covers mechanical system simulation
(MSS) concepts that will help you use ADAMS most optimally. The earlier workshops provide
you with more step-by-step procedures and guidance, while the later ones provide you with less.
Each module is divided into the following sections:
1 Problem statement
2 Concepts
3 Workshop
4 Module review
