AV TEST BENCH is a complete research-educational test bench for rotating machinery diagnostics. It consists of the mechanical part, the vibration-based condition monitoring system and diagnostics software. The mechanical part, placed on stiff support, includes two three-phase asynchronous motors with frequency inverters (one of them acting as propulsion, the other one as load), a gearbox, a shaft supported on three rolling element bearings (one of which is mounted on an adjustable screw and can be used to apply vertical force to the shaft, thus loading the bearings supporting it). The shaft has got a disc with holes designed for imbalance simulation. The diagnostic part is comprised of a full-featured condition monitoring system AVM 4000, four AVS1000 accelerometers, one rotational speed sensor and VIBnavigator software:
- AV SENSOR 1000 – general purpose industrial accelerometer with isolated AC output
- AV MONITOR 4000 – module for acquisition, conditioning and real-time data processing
- VIBnavigator – software for visualization and diagnostics with advanced signal-processing algorithms
