Machinery Structural Analysis

Rotating machinery dynamics are best understood when structural and rotary dynamics are considered.  With RPM measurements available throughout all structural analysis applications, SignalCalc 900 offers a robust solution to analyzing complex rotating machines and their supporting structures.

RPM Measurement

Measure RPM accurately with the high speed tachometer hardware

RPM Triggering

Trigger measurements based on RPM or RPM increments to collect steady state or ramp-up/ramp-down data 

RPM based 3D plots

Visualize structural resonances and their excitation caused by rotating machines on 3D Waterfall or other plots

Engine Order Analysis

Automotive test engineers use order tracking methods to evaluate both rotating components and vehicle drivelines. Order tracking easily separates forced vibrations caused by the revving engine from the structural response of resonances.

Order Normalization

Specify RPM range of interest, the max order, and the desired delta order and the system automatically selects the propper measurement parameters.

3D Plot Visualization

Choose from waterfalls, color mesh, color cascade, campbell plots, spectrograms, and more.

Simultaneous FFT Measurements

Simultaneously run FFT measurements (multi-measurement) to take FFT based and RPM based measurements simultaneously – no need for post processing
