Modal Analysis Testing

Modal analysis of automotive structural assemblies using LMS facilities.

LMS Test Lab Software + Scadas III Hardware system can be used for a wide range of noise and vibration testing. It includes a high speed multichannel data acquisition system, (8 24-bit channels up to 200KHz), and software that enables the determination of frequency response functions of vibrating components or more generally complete modal analysis to be carried out on automotive equipment that can be used to validate finite element analysis.
