MESA Random Vibration Testing
Multiple-Exciter Single-Axis Random Vibration Testing
The MESA Random vibration testing 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.
Multiple-Exciter Single-Axis (MESA) Random Vibration Testing
MESA Vibration 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 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 vibration test.
Monitoring Through EDM Cloud
All vibration 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.
