We perform calculations that make mechanical designs buildable, safe and predictable in service. The scope covers power and torque, shafts and bearings, welded and bolted joints, and structural members sized to standards. For example, conveyor drives are checked for power/tension and belt geometry before drawings are released. Therefore, fabrication and installation proceed without guesswork.
Mechanical engineering calculation — scope & methods
Scope we cover
Power, torque and energy: drive sizing, duty cycles, start/stop and overloads.
Shafts and bearings: torsion/bending, combined stress, deflection, bearing life (L10/L10h).
Keys, splines, couplings and hubs — stress and fit checks.
Welds and bolted joints: static/fatigue, prying, preload and slip resistance; sensible tolerances.
Plates, frames and brackets: bending, buckling and stiffness to Eurocodes.
Kinematics & mechanisms: linkages, motion envelopes and clearances.
Thermal/expansion notes for housings and guards where relevant.
Interfaces to vendors: motors, gearboxes, belting, rollers and profiles.
Methods and standards
Closed-form calculations with clear assumptions and safety factors.
Load cases/combinations to EN 1990/1991; steel per EN 1993; execution notes to EN 1090.
Guarding/access aligned to relevant EN/ISO machinery standards.
In addition, critical details may be verified with FEA — see Strength calculation (FEM).
Deliverables
Calculation notes or concise reports (PDF) showing inputs, method and result.
Supporting spreadsheets where applicable; clear pass/fail vs. acceptance criteria.
References to drawings/models (DWG/DXF/STEP/PDF) and BOM items.
Therefore, suppliers can fabricate and assemble without rework.
Boundaries
We don’t certify foundations/civil works or act as a notified body. Process/CFD studies are outside scope. However, we coordinate with your specialists and incorporate their requirements.
