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.

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).

The APS Dynamics Power Amplifiers are designed specifically to provide drive any vibration and modal exciter requiring 500 VA (Model 125) or 810 VA (Model 145). The output stage uses proven high reliability power operational amplifiers arranged to produce a balanced output.

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.

Navcon engineers have a strong background in physics, mechanical design, digital data acquisition, vibration and noise. This combination of theory & application, analysis & test allows us to attack a wide variety of vibration or noise related projects. Following is a brief list of our general vibration services:

SoundPLAN is an acoustic ray tracing program for noise propagation prediction written by the German acoustical consulting firm, SoundPLAN GmbH.
