The toolbox for modal analysis, mechanical
simulation, and system identification

Overview
ModalTools™ has been designed for the engineer who uses MATLAB to analyze and/or simulate noise and vibration signals and systems. The Toolbox includes functions for experimental modal analysis.
It simplifies generation of typical functions such as frequency response functions from given models for simulation purposes.
In addition, functions for computation of frequency response functions and coherence functions from time data are included, both for single-input and multiple-input systems. Also, some typical modal analysis functions that simplify forced response analysis and operating deflection shape analysis etc are found
in the toolbox.
This toolbox can work as your only tool for modal analysis, or as a complement to any commercial modal analysis software, adding flexibility and functionality for post processing modal data.

Key Features • Standard data storage format with header values for noise and vibration signals, such as measurement position, direction, etc. • Import/export of modal data in universal file format

• Modal analysis parameter extraction using SDOF and MDOF methods, including multi-reference methods.

• Estimation of frequency response functions for single-input/single-output and multiple-input/multiple-output, including ordinary and multiple coherence

• Source identification by partial coherence and principal response analysis

• Synthesis of frequency response functions from M, C, and K matrices

• Unique time domain filtering functions for computation of forced response of experimentally or analytically defined mechanical systems
