ANSYS Random Vibration (Traditional GUI)

Prerequisites

B.S. degree in engineering or engineering experience. Introduction to ANSYS (Traditional GUI) and Dynamics or equivalent ANSYS experience is required.

Description

This two-day course presents an introduction to the theory of random vibration analysis and describes techniques used to predict failure due to random excitation using the ANSYS general purpose finite element program. The course objective is to enable the attendee to perform a structural evaluation of a design which is subjected to a random vibration environment. Concepts will be introduced from a theoretical perspective to explain underlying principles and assumptions. However, the course emphasizes a practical, industry-oriented, approach to performing random vibration analysis using ANSYS. Examples will be used to illustrate the application of the theory to a practical engineering problem. These will be reinforced by in-class workshop problems.

Topics Include:

  • Overview of Structural Evaluation of Equipment Subjected to Random Vibration
  • Understanding Random Vibration
  • Characteristics of a Random Process
  • Working With PSD Functions
  • Mathematical Modeling of Dynamic Mechanical Systems
  • Excitation - Response Relations For Linear Systems
  • Response of SDOF System to Random Excitation
  • Response of Multi-DOF System to Random Excitation
  • Calculating a System's Random Response Using an ANSYS Finite Element Approach
  • Evaluating Structural Performance – Using the Results of Random Vibration Analysis
