Introduction Course Overview

DRD’s ANSYS Mechanical Structural Dynamics Course

The objective of this course is for attendees to develop significant expertise in the use of ANSYS Workbench for dynamic analysis over a wide range of applications. The course emphasizes linear dynamic analysis, although it has one chapter and one workshop on nonlinear transient dynamic analysis. DRD collaborated with one of its customers, a large defense electronics firm, to develop this course.

The course deemphasizes theory of dynamics and emphasizes good ANSYS modeling practices and verification of correct answers. DRD recommends using closed form equations based on solutions to single degree of freedom models to verify solutions to complex multiple degree of freedom models. In the course students use hand calculations to check solutions to normal models, random vibration, response spectrum, and half sine shock models.

The course includes 10 workshops in which the students use techniques covered in the course to solve real-world problems. All of the workshops are based on actual problems that DRD has solved for customers on a consulting or technical support basis. Two of the workshops have minimal instruction so that students can begin testing their skills under the supervision of an instructor during the course.

Prerequisites for this course are DRD’s Introduction to Workbench and DesignModeler courses in addition to practice gaining proficiency with Workbench Simulation. DRD recommends that students who do not have these prerequisites delay attending the course until they attain them. This is a challenging course for proficient users
