Rotating Machinery Diagnostics and Vibration Analysis

Large Industrial Rotating Machinery Diagnostics:

Factory acceptance testing of large, industrial rotating machines often requires complete and accurate documentation of vibration characteristics including measurements for shaft and housing vibration analysis. Well-suited for high-speed balancing and factory test cell environments, the SignalCalc Turbo vibration analyzer provides measurement and graphical tools for analysis of seismic and proximity probe displacement signals, as well as a straightforward user setup, automated reporting, data export, and traceable in-house calibration. For rotor dynamics testing, SignalCalc Turbo includes special utilities for measurement of empirical data necessary for validation of rotor dynamics models and unbalance response simulations.

In the field, turbomachinery in power generation or process industry service may also require acceptance testing, balancing, or troubleshooting. For field specialists, the same quality of measurements for shaft and housing vibration analysis must also be available in a mobile package. The SignalCalc Turbo vibration analyzer brings to rotating machinery experts unlimited expandability and comprehensive machinery diagnostics capabilities in a modular, portable package for machinery vibration analysis in-situ on the machine deck.

General Rotating Machinery Applications:

Cost-effective and non-destructive, rotating machinery vibration analysis and diagnostics are now, more than ever, key initiatives towards ensuring reliable operation of rotating machinery. Steam turbines, gas turbines, generators, motors, pumps, compressors, gearboxes, aircraft engines, fans, blowers, turbochargers, drive trains, and machine tools are examples of rotating machinery required to operate efficiently and safely, or consequences can be catastrophic both in terms of safety and operational costs. To help users achieve this aim, SignalCalc Dynamic Signal Analyzers employ a wealth of measurement options for a variety of applications ranging from shaft vibration measurement on large turbomachinery, to modal analysis of supporting structures, to order analysis of automotive engines and drive trains.

Machinery Structural Analysis:

Because rotating machinery dynamics can best be understood when the entire system is considered, rotating machinery analysis experts commonly employ both structural and rotor vibration analysis techniques. This means not only measuring shaft vibrations, but also analyzing vibrations and characteristics of the supporting structure to ultimately determine how rotor and structure dynamics interact. SignalCalc Dynamic Signal Analyzers provide transfer function techniques for impact hammer testing of structures, and also export data, both real-time and post-acquisition, for 3-dimensional viewing of structure Operating Deflection Shape (ODS) displays.

Engine Order Analysis:

Automotive test engineers use order tracking methods to evaluate both rotating components and vehicle drivelines. Noise, vibration and harshness (NVH) testing is extremely common in the automotive industry because it yields competitive advantage. Order analysis is often combined with both vibration and acoustic measurement to evaluate the total effect of rotating vibration harmonics, or orders. SignalCalc Dynamic Signal Analyzers perform sampling of input signals synchronized with the instantaneous angular position of the machine shaft using a resampling technique. Rather than a constant number of samples per time, this results in a constant number of samples per revolution and transforms the analysis to the order domain rather than the frequency domain.
