MESA Random Shaker Systems

Multiple-Exciter-Single-Axis Random Vibration Testing Shakers

The MESA Random Vibration Control system provides precise, real-time, multiple excitation single channel control and analysis. After the control channels are assigned, the remaining input channels can be set up as monitoring and time data recording channels. The recording option records time stream data at the full sample rate on all input channels.

Test Parameters

The random control related test parameters can be user defined. Various test parameters like number of lines, average number/control DOF, H update ratio, frequency resolution etc. can be configured to fine tune and optimize the MESA random vibration control test.

Weighted Average Control Strategy

Multiple control and monitor channels can be configured in the input channel settings. Weight can be individually assigned to each control channel.

Phase Optimization

Furthermore, different relations between the control channels can be established like same magnitude and phase for drives, different phase for drives, different magnitude/phase for drives, can be set for a MESA random test.

Monitoring Through EDM Cloud

All tests in EDM-VCS support status checks through EDM Cloud. With EDM Cloud support, users can set up any VCS test to upload live data or run logs for completed tests to a cloud storage space provided by Crystal Instruments, where data is securely stored in the user’s account.

The EDM Cloud website is located at https://cloud.go-ci.com. Users can access EDM Cloud from anywhere in the world to check the status of past and current tests. A secure login flow ensures the status can only be checked by authorized personnel with proper credentials. Multiple logins for accessing the same Cloud account is available.
