Multi-Sine vibration testing can simultaneously sweep multiple sine tones, helping reduce test time and excite multiple resonant frequencies at once. Independent tracking filters are applied to each tone separately. Includes support for notching and limiting.
Number of Sine Tones: up to 10 tones
Configuring Sine Tone Frequencies: evenly split across spectrum, manually defined, or set as harmonics
Operation Controls: Tone On and Tone Off controlled by run schedule or manual command
Number of Inputs: supports up to 512 input channels
Unique Features in Multi-Sine Vibration Testing
Vibration Visualization: The EDM Vibration Visualization feature is available in EDM VCS software all test types, including MIMO VCS. This option provides fast and efficient structural model generation and full 3D visualization of the online vibration pattern on the structure under test.
Multiple instances of EDM VCS can run simultaneously on the same computer. Each instance connects a Spider system to run the vibration controller software. All instances must run different tests. This feature provides a central place to control multiple Spider systems and perform vibration tests separately.
Black Box Mode: Operating Without a PC
A supported front-end can operate in Black Box mode which allows it to perform a test without a connected PC. In this mode, a PC is used only to configure the system before the test and then to download the data after the test is complete.
Multi-shaker control (MSC) is a unique feature offered enables users to view and monitor multiple shaker tests from one PC station. Up to 12 controllers can be accessed simultaneously.
