Medical Autoclave Stress Analysis and Fatigue Life Prediction

Mechanika has recently completed a static stress analysis and detailed fatigue analysis for an autoclave, which had been designed and prototyped by a client in the medical instrumentation sector. The project consisted of full substantiation and compliance with “BS EN 13445-3: Unfired Pressure Vessels – Design”, supplemented by detailed fatigue data from Mechanika Ltd.’s expansive…

2-tonne SWL Aerospace Lifting Beam

Mechanika Ltd provided a full design life-cycle stress analysis for the design of a bespoke lifting beam for carrying aerospace payloads up to 2 tonnes. Structural sizing was carried out at project initiation which was underpinned with FEA to show compliance with customer requirements and lifting code permissible stresses. From here, the customer was able…

Deep Sea Measuring Device FEA

A sensitive deep sea magnetic measuring device was assessed by Mechanika, to demonstrate its structural conformance at 2.2 km submersion. A detailed non-linear contact and material study was undertaken to understand working level performance at depth and also ultimate failure analysis to determine the maximum safe working depth of the device.

Compression Plate Fatigue Analysis

Mechanika undertook an FEA study to investigate the working stress cycles within a heavy-duty compression plate fabrication. The assembly was modelled using shell and solid higher order elements. The principal stress magnitudes were calculated via FEA and a fatigue life prediction was carried out for the client. Mechanika also advised on the redesign of the…

Boom Structural Analysis and Redesign

A complete structural analysis in-line with the rules set out in F.E.M Section 2, Document 2 131/ 2 132, was undertaken by Mechanika, for a 30 m feeder boom. The total structural mass when fully laden was 61 tonnes and the operational distributed load on the boom conveyor was 4.75 tonnes. The analysis comprised the assessment…
