Adams Multibody Dynamics Simulation

Adams is the most widely used multibody dynamics and motion analysis software in the world. Adams helps engineers to study the dynamics of moving parts, how loads and forces are distributed throughout mechanical systems, and to improve and optimize the performance of their products.

Traditional “build and test” design methods are now too expensive, too time consuming, and sometimes even impossible to do. CAD-based tools help to evaluate things like interference between parts, and basic kinematic motion, but neglect the true physics-based dynamics of complex mechanical systems. FEA is perfect for studying linear vibration and transient dynamics, but way too inefficient to analyze the large rotations and other highly nonlinear motion of full mechanical systems.

Adams multibody dynamics software enables engineers to easily create and test virtual prototypes of mechanical systems in a fraction of the time and cost required for physical build and test. Unlike most CAD embedded tools, Adams incorporates real physics by simultaneously solving equations for kinematics, statics, quasi-statics, and dynamics. Utilizing multibody dynamics solution technology, Adams also runs nonlinear dynamics in a tiny fraction of the time required by FEA solutions. Loads and forces computed by Adams simulations improve the accuracy of FEA by providing better assessment of how they vary throughout a full range of motion and operating environments.

Complete pre/post-processing for realistic & accurate modeling

The Adams product family provides a set of interactive motion simulation software modules. The core package (Adams/View, Adams/Solver, and Adams/PostProcessor) allows you to import geometry from most major CAD systems or to build a solid model of the mechanical system from scratch. A full library of joints and constraints is available for creating articulated mechanisms. Once the virtual prototype is built, Adams checks the model and then runs simultaneous equations for kinematic, static, quasi-static, and dynamic simulations. Results are viewable as graph, data plots, reports, or colorful animations that you can easily share with others. You can use the results (loads created from different types of motion) of Adams simulation studies to provide loads for many different FEA programs including Nastran to optimize the structure of a design.

Add-on modules provide capabilities that grow with your company

Several modules that are part of Adams can be used to accomplish specialized tasks and achieve better fidelity of results. For example, Adams/Flex can be used to examine the impact of flexible parts on the mechanism and Adams/Controls can be used to model control systems such as hydraulics, pneumatics, electronics and more. Adams also offers a range of modules tailored to industry specific applications. Several CAD interface modules allow you to explore the motion of CAD designs without having to leave a familiar CAD interface or transfer data into Adams.
