The provided document is a manual for the VibrationVIEW software and the VR8500 vibration control system. It details the setup, operation, and maintenance of the system, along with various software features.
The VibrationVIEW is a signature software package designed for vibration control, primarily for electrodynamic and servohydraulic shakers. It includes a "System Check" mode for testing and calibrating the shaker system. Optional modules extend its functionality to Sine, Random, Classical Shock, RecorderVIEW, Field Data Replication, Sine-on-Random, and Random-on-Random tests. The software is designed to be user-friendly and reliable, with a focus on quality and superior performance.
The VR8500 is the hardware component, an I/O box that interfaces with a computer and shaker system. It is powered by 90-250 VAC and 50/60 Hz, with automatic line voltage sensing.
Function Description:
The VibrationVIEW system allows users to define, run, and analyze various types of vibration tests. It provides real-time control and monitoring of shaker systems.
- System Setup: The software guides users through installing hardware and software, configuring input channels, and calibrating accelerometers.
- Test Definition: Users can define different test profiles, including Sine, Random, Classical Shock, and Field Data Replicator tests. Each test type has specific parameters for amplitude, frequency, duration, and control loop behavior.
- Test Execution: Tests can be started, stopped, paused, and advanced through levels. The system provides real-time feedback on test status and output levels.
- Data Management: The software allows for storing, retrieving, and exporting test data in various formats (VibrationVIEW Data File, Report Document File, Text File, Spreadsheet File, Matlab File, Meta File, Bitmap File, PNG File).
- Reporting: Customized reports can be generated, including data values and graphs, with options for printing, emailing, or saving to file.
- Remote Control: VibrationVIEW can be integrated with remote applications using Remote Inputs (for control and monitoring) and ActiveX for more advanced control. A Web Server option allows remote monitoring and control via a web client.
- Waveform Import/Export: Field Data Replicator waveforms can be recorded from the VR8500 input, imported from UFF or ASCII text files, and exported to Windows .WAV files.
- Controller Tuning: Parameters for Sine, Random, Sine-on-Random, Classical Shock, and Field Data Replicator tests can be tuned to optimize control loop response and stability.
