Mechanika successfully substantiated a carbon fibre bonnet opener jig for a client in the automotive sector. The bonnet opener is used to support the weight of the bonnet and also provide restraint in the event of impact and other user fault cases. Prior to detailed FEA in ANSYS Mechanical Workbench 2020 R1, preliminary hand calculations…
Mechanika recently carried out a full design optimisation and analysis of a bespoke turnover machine for part of a satellite assembly. The assembly was initially assessed with traditional stress hand calculations to Eurocode 3 and BS EN 13001 Crane code series, which was then verified with detailed FEA using RFEM5 and ANSYS Mechanical Workbench 2020…
Mechanika is supporting a large UK client, in the structural scheme design of a mining facility in Eastern Europe. Mechanika have been responsible for the structural scheme design for a suite of buildings, conveyors, culverts and towers, which are being constructed in and around the facility. The following images show one of Mechanika’s portal frame…
Mechanika have recently analysed a plastic pressure vessel for a beverage brewing company in the UK. The bottle was designed for 3 bar working pressure and 6 bar proof pressure. Mechanika assessed the following items using FEA in ANSYS Mechanical Workbench 2020 R1 and hand calculations: Static pressure analysis Combined thermal analysis Creep Assessment Fatigue…
Mechanika carried out a detailed stress analysis of an Electrical Control Cabin which was situated in California. The assessments were executed in-line with EU and local California legislation and the structure was assessed to the requirements set out in the following design codes: BS EN 1993-1-1 Eurocode 3 General rules buildings BS EN 1993-1-8 Eurocode…
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…
Mechanika Ltd recently carried out a full substantiation analysis of a prototype bell crank mechanism on a small aircraft engine. The scope of the analysis was as follows: Identification of the weakest structural link using mechanics and stress hand calculations. This was executed to enable a fast communication of the load path through the…
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…
Mechanika Ltd recently undertook a full structural analysis of a 5-tonne aluminium staging structure for the aerospace sector. The structure was verified by detailed hand calculations followed by beam modelling in RFEM5 FEA. The analysis was executed in-line with the rules set out in: “BS EN 1999-1-1 Design of Aluminium Structures” The staging structure was…
The mobile hopper facilitates the loading and unloading of ships and provides a means of storage and transportation of materials. Mechanika ltd carried out the entire structural assessment and structural design of the hopper, which in an overloaded case could sustain loads of 600 tonnes. The load cases assessed covered all static and dynamic scenarios…
