NVH, Fatigue, & Frequency Domain Analysis with Ansys LS-DYNA
Traditionally LS-DYNA is well known as an advanced transient nonlinear finite element software. However, during the extended application of LS-DYNA in automotive and other industries, many users requested frequency domain analysis capabilities and fatigue analysis capabilities in LS-DYNA. These capabilities are essential for performing vehicle NVH (noise, vibration, and harshness) analysis and durability analysis. To answer the requests of the users, a series of frequency domain analysis features and fatigue analysis features were implemented to LS-DYNA.
This class provides you with a comprehensive introduction for the features for frequency domain vibration, acoustic and fatigue analysis in LS-DYNA. Time domain fatigue analysis is also included to make the fatigue analysis module complete. Introduction of some advanced capabilities in this area, such as brake squeal analysis based on rotor dynamics, NVH analysis based on IGA technology and SEA (Statistical Energy Analysis), is also included. This class also gives a detailed look at the application of these features in vehicle NVH and durability analysis. During the class, workshop examples are provided to help understand the corresponding keywords and the workflow for solving the problems.
- Understanding of the frequency domain analysis and fatigue analysis keywords in LS-DYNA
- Understanding the vibro-acoustic and vibro-fatigue analysis workflow
- Understanding the necessary linearization of the nonlinear model for NVH analysis
- Learning the pre and post-processing for the frequency domain analysis and the fatigue analysis
You should have basic knowledge of LS-DYNA.
Target Audience: Engineers and researchers who are working in the area of vehicle NVH, aircraft / spacecraft vibro-acoustics, engine noise simulation, machine vibration testing and simulation, etc.
Teaching Method:Lectures and computer practical sessions to validate acquired knowledge.
Learning Options: Training materials for this course are available with an Ansys Learning Hub Subscription. If there is no active public schedule available, private training can be arranged. Please contact us.
