Vwin II Vibration Control & Analysis System

The Vwin II offers the latest technology in digital signal processing and shaker control algorithms providing real time vibration test control for random, sine, shock, SRS, random on random, multi-tone sine on random, TRAC (time replication acceleration control) vibration testing and transducer calibration, a well as extensive data acquisition and analysis. The modular software may be initially customized for specific applications or easily expanded in the future without performance penalties. It provides an abundance of comprehensive features that ensure simple, safe, accurate and reliable testing.

Pentium Workstation

The Vwin II is based on a standard Pentium PC, the most popular computer platform in the world. The 32 bit Vwin II Application Software utilizes familiar Microsoft Windows XP user interface features, making operation intuitive and easy to learn without extensive training.

Performance

The Vwin II DSP surface mount hardware provides parallel 16 bit A/D input channels with sampling rates up to 51.2 kHz and anti-aliasing filters. Two 16 bit output channel D/A’s are sampled simultaneously with the input channels and are combined with reconstruction filters for transient-free operation. Each input and output is combined with 24 bit scaling stages, providing over 90 dB dynamic range. The DSP plug-in boards incorporate the versatile and well proven TI floating point signal processor chip. While graphics related processing is reserved for the Pentium processor, the powerful DSP boards are used exclusively for control loop processing, assuring accurate real-time control and simultaneous data acquisition. The CCS option provides constant current excitation for voltage type (ICP) accelerometers. This feature eliminates the need for separate signal conditioning instrumentation.

Test Library

An extensive library of Vwin II software modules is available with an unprecedented number of functions and features to satisfy basic testing needs, as well as, advanced applications, data acquisition, and specialized custom testing.

Expandable

The Vwin II controller is available in 4, 8, or 16 channel configurations. Expanding an existing 4 channel or 8 channel system can be accomplished simply by exchanging or adding the necessary DSP boards. Modular software provides the flexibility to add test capability as test needs grow.

Safety & Security

Safety checks are provided in the Vwin II software to protect against operation beyond shaker system limits and to prevent test initiation without proper control feedback. Password protection allows selectable security in terms of operator access to test modes, test data, and specific test setups.

Network Ready

Every Vwin II is configured with network-ready hardware for easy configuration and access with other Vwin II, the network server and other network clients.

Factory Integrated

All Vwin II hardware and software is factory installed, fully integrated and tested to ensure quick and successful operation at the user site. An optional Calibration Kit is available for those customers that elect to calibrate the Vwin II on-site.

Portable Workstation (PACS)

A rugged portable workstation option (PACS) allows the Vwin II to become a mobile controller and/or data acquisition system, an option especially useful for collecting vibration data in the field for later reproduction on a shaker in the lab.
