Machine FEA and structural assessment

What the assessment covers

The package defines the geometry, loading assumptions, supports, operating configurations and assessment criteria. Depending on the machine and scope, checks may include strength, serviceability, fatigue, balance and stability.

Imported geometry is an input to model development. It still requires engineering decisions about properties, connections, restraints and loads. Model checks and engineering calculations test whether the analysis represents the physical machine.

Calibrate against measured machine response

For an operating machine, ACE compares predicted response with suitable luff trends, SCADA records and other relevant site measurements. The comparison uses the current machine configuration, confirmed geometry and equivalent loading and test conditions.

For hydraulic luffing, force estimates use pressures from both cylinder chambers and their effective areas, plotted against boom angle. Sensor accuracy, measurement locations, friction and the direction of movement affect the comparison. Differences are investigated before model inputs are adjusted, with changes supported by machine records or measurements.

Where data is missing or unsuitable, the assessment identifies the measurements needed and the limits of the model. For a new machine, the scope can include a commissioning plan to compare predicted and measured response once the machine is available.

Calibration supports the assessment within the checked range. Matching a luff trend does not establish the capacity or compliance of the complete machine; design verification and any required certification remain separately defined.
