Enabling Easy Simulation & Testing with Advanced Motion Analysis Solutions

A Multibody Dynamic (MBD) system comprises solid bodies or links, that are connected by joints that limit their relative motion. Forward Dynamics is the analysis of how mechanism systems move under the influence of forces, while the study of the forces necessary to make these mechanical systems move in a specific manner is inverse dynamics.

A robust product design calls for an in-depth understanding of how multiple moving parts interact with each other and their environment as well. Whether it’s automobiles, aircrafts, washing machines or assembly lines, it is difficult to predict the loads generated. To meet the design challenges presented by the complex mechanical assemblies, a dynamic system level analysis is imperative. Accurate modeling requires representations of various types of components as well as complicated physical phenomena.

Motion analysis empowers engineers to address these challenges by quickly evaluating and improvising designs for important parameters like performance, safety, and comfort. MSC’s motion analysis solutions offer an extensive range of multi-body dynamics simulation functionalities through the enhanced, convenient pre- and post-processing interfaces and industry leading solvers.

Key Features

CAD integration

Import CAD neutral geometry formats (STEP, IGES, DXF, DWG, Parasolid) and native CAD geometry formats (Catia V4, Catia V5, Inventor, STEP, IGES, Acis, ProE, Creo, SolidWorks, Unigraphics, VDA)

Flexible body analysis

The new ViewFlex module in Adams/View enables users to transform a rigid part to an MNF-based flexible body using embedded finite element analysis where a meshing step and linear modes analysis will be performed. Powered by MSC Nastran, it’s a simplified process giving users much greater efficiency than the traditionally generated flexible bodies.

Multidiscipline Mechanical system Simulation

With functionalities like Adams2Nastran export and ViewFlex, Adams allows bi-directional integration with MSC Nastran. Adams/Mechatronics easily integrates control systems into mechanical models by dynamically linking an external system library from a controls application such as Easy 5 and MATLAB. Control systems parameters can be quickly adjusted for evaluation and incorporated in design study for parallel optimization of both control system and mechanical system.

Contact Modeling

A variety of contact modeling functionalities are provided so rolling and sliding contacts and impact can be represented between rigid bodies, flexible and rigid bodies as well as between two flexible bodies. For simple geometries, Contact primitives provide a competent solution while more sophisticated methods are used for contact between complex geometries.

Durability analysis

Durability testing is an essential aspect of product development. MSC solutions enable you to assess stress, strain, or life of components in your system model. By interfacing to fatigue programs life predictions and factor-of-safety analyses are possible. Model correlation, along with Process streamlining is enabled by leveraging direct access to physical test data in industry-standard file formats.

Vibration analysis

Perform system-level vibration analyses such as frequency response studies and normal modes analysis. The vibration-specific modeling elements coupled with vibration and frequency-domain specific post-processing, leads to easy analysis and visualization of system modes, frequency response, modal participation tables, component energy distribution, etc.

Control system integration

MSC’s motion analysis solutions enable easy integration of mechanical systems and control system models. Incorporate mechanical models within block diagrams of the control system design software itself or directly import the actuators and/or controllers from the controls design software in the mechanical system simulation environment. Such interactions are supported with MATLAB (Simulink) and EASY5 software.

DOE & optimization tools

MSC offers planning and analysis tools for running a series of experiments that help to determine relevant data to analyze, and which automates the entire experimental design process, which is otherwise a time-consuming task when trying different factor combinations. This improves the reliability of the results, gets results quicker than trial-and-error or testing one factor at a time and helps you suitably optimize the performance of your mechanical system.

Customization & automation

The motion analysis solutions offer multiple means of automating the model construction, solving and post-processing activities. Here model construction can be automated through macros or templates. Custom interfaces can be created and directly integrated into the "off-the-shelf" tool.
