Analytical Torsional Critical Speed Study
Budget: ₹1,500 – ₹12,500 INR
I have a multi-disk rotor and need its torsional behaviour mapped out so I can confidently avoid any critical-speed issues.
What I need from you
• A clear derivation of the governing equations and the model you adopt for the individual disks and shaft segments.
• Calculation of natural torsional frequencies and identification of the critical speeds across my operating range.
• Campbell diagram or equivalent visual that highlights any resonance crossings.
• A concise report (PDF) explaining assumptions, step-by-step calculations, and conclusions, plus the raw calculation file (Excel, MATLAB, or Python script) so I can reproduce the results.
Acceptance criteria
• Calculated critical speeds must be traceable through your worksheets with units and consistent notation.
• Any simplifying assumptions (e.g., negligible disk inertia coupling) are stated and justified.
• Results align within industry-standard tolerance when spot-checked against hand calculations.
If this fits your analytical toolkit, I’m ready to supply geometry, inertia data, and operating speed range as soon as we start.
