1. Summary

This report documents design and analysis information created and maintained using Autodesk Inventor Professional 9.0 and ANSYS software. The scenario listed below represents a complete engineering simulation.

Scenario 1

2. Introduction

ANSYS CAE (Computer-Aided Engineering) software was used in conjunction with Autodesk Inventor solid geometry to simulate the behavior of a mechanical body under structural loading conditions. ANSYS automated FEA (Finite Element Analysis) technologies from ANSYS, Inc. generated the results listed in this report.

The scenario presented below represents one complete engineering simulation. The definition of a simulation includes known factors about a design such as material properties per body and types and magnitudes of loading conditions. The results of a simulation provide insight into how the body may perform and how the design might be improved.

The discussions below follow the organization of information in the AIP Stress "Browser" user interface. Names emphasized in "double quotes" match preferences set in the user interface.

All values are presented in the "U.S. Customary (in, lbm, psi, °F, s)" unit system.

Notice

Do not accept or reject a design based solely on the data presented in this report. Evaluate designs by considering this information in conjunction with experimental test data and the practical experience of design engineers and analysts. A quality approach to engineering design usually mandates physical testing as the final means of validating structural integrity to a measured precision.

  • The bounding box for the model measures 3.0 by 2.0 by 1.0 in along the global x, y and z axes, respectively.
  • The model weighs a total of 1.27 lbmass.

    A3. Glossary

    Bounding Box
    A three-dimensional cube aligned to the global x, y and z axes that exactly contains a body or assembly.
    Relevance
    Defines the acceptable accuracy for a body and valuates the importance of bodies in an assembly. The relevance range extends from -100 to +100, where -100 implies maximum software speed and +100 implies maximum accuracy in calculating results.
    Scope
    Filters a result to selected geometry. If combined with convergence tracking, focuses refinement activity on the selected geometry.
    Visible
    A user preference that controls the visibility of bodies in figures in this report. Unlike suppressed bodies, invisible bodies are fully considered in the calculation of results.
