Modal Analysis has been a key part of the product development process for the past 30 years. Covering component
benchmarking, sub-system analysis and full-system design verification activities, the discipline has evolved with
development processes from being a purely test focused activity to more recently supporting simulation based
design processes through model validation, correlation and updating.
We kindly invite you a seminar that will introduce modal analysis as a relevant work flow to the modern engineering
process and demonstrate, through efficient testing and use of data, the benefits it can bring to your organisation.
This seminar will cover:
• An introduction to modal analysis and its use in the product development cycle
• An overview of the theoretical concepts required for accurate data acquisition and modal model creation
• Practical hands-on demonstrations of a component through pre-test, data acquisition and analysis
• A hybrid test / CAE case study demonstrating the integration of the test data into the CAE analysis environment
Agenda – seminar will start at 09:00 and will finish at 15:30
Morning session
Afternoon session

• Modal Analysis Overview?
-- What is Modal Analysis
-- What attributes are effected by a systems modal performance
-- When do we use modal analysis in the product development cycle
-- What are the benefits of the correct tool selection for modal
testing and analysis
• Practical Modal Analysis: Pre-Test Basics (with demos)
-- Digital Signal Processing for modal analysis
-- Excitation options, hammer vs. shaker, SISO, SIMO and MIMO
-- Excitation position
-- Test specimen preparation
-- Pre-test checks
-- Typical test need to knows
• Practical Modal Analysis: Basic Data Analysis (with demo’s)
-- The modal model and parameter estimation (theory)
-- Geometry creation
-- Parameter estimation, modal order, the stabilization diagram
-- FRF synthesis, correlation, effect of residual terms
• Break
• Practical Modal Analysis: Advanced Data Analysis (with demo’s)
-- Modal validation tools: modal assurance criterion, mass
sensitivity, mode participation, phase scatter
-- Modification prediction
-- Rigid body property estimation
• Modal Analysis in the Development Cycle
-- Case study of how modal analysis data is incorporated into the
development process. Test / CAE correlation and modal
• Q&A & Closing
