Navcon Engineering was contracted to conduct the modal survey of the High Energy Solar Spectroscopic Imager (HESSI) spacecraft. The primary objective was to identify the damped natural frequencies, damping factors and mode shapes in the frequency band between 70 Hz. and 170 Hz.

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.

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.

dBSea has been developed by Marshall Day Acoustics as a powerful tool for the prediction of underwater noise in a variety of environments.

dBSea is ideal for the investigation of underwater acoustic problems involving single or multiple sources using solvers covering a wide frequency range.

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).

SoundPLAN-essential is a single document application including all the basic information for noise control modeling and planning. It calculates noise from roads, railways or industrial noise sources. The computation can include one or multiple noise sources.
