Hands-On Modal Testing
SIDLAB Acoustics
SIDLAB Double Plug Muffler Model Schematic

This module models the generation and propagation of low frequency sound in complex duct networks. The frequency range is limited to the plane wave region in the connecting pipes. It is based on linear acoustic theory and all elements, e.g., a complex muffler, are reduced to two-ports while terminations and sources are represented as one-ports.

Hands-On Modal Testing & Analysis Training
Impact Modal Testing

This marks our 25th year presenting the Hands-On Modal Testing Seminar. Join the more than 1000 engineers and technicians who have tested a Navcon JimBeam and a fully race prepared Porsche (One of the classes this year will be the first to conduct a modal test on the new Porsche 991 GT3).

Validation and Updating of FE Models for Structural Analysis

During this FE Model Validation and Updating seminar, the participants will not only learn the basic principles of test-analysis correlation and finite element model updating, but also get hands-on experience using specialized software (FEMtools).

Air Bearing Horizontal Shakers

The APS Dynamics series of air bearing long stroke vibration exciters provide excellent properties for low frequency excitation of accelerometers and other low frequency instruments and sensors. Some models have a horizontal air bearing table coupled to the driver unit that allows high payloads up to 23 kg e.g.

SIDLAB Measurement

SIDLAB Measurement

This is a post-processing module for measurement data. It handles two types of measurements: 

Portable Shaker-Amplifier

The APS Dynamics Model 300 Portable Shaker is a self contained shaker and amplifier in an aluminum carrying case. For operation, the unit separates into two sections - the Amplifier Section and the Shaker Section


The APS 0109 Zero-Position-Controller automatically controls the zero position of a vibration exciter irrespective of the payload. It is essential to employ a position controller of type APS 0109 especially when working with a vibration exciter without any integrated load compensation.


Dynamic Design Solutions ("DDS") is an independent and privately owned developer of CAE software tools for a growing number of applications that exploit the combined use of experimental test data and finite element analysis data and for integrating and automating different CAE tools.
