I have designed a device consisting of several discs mounted on a horizontal shaft. The complete assembly rotates slowly while partially/substantially immersed in water. I am looking for an engineer experienced in mechanical FEA / shaft design to evaluate the current design and help optimize a new lightweight shaft. Phase 1 – Analysis of the existing shaft The current shaft is made of stainless steel. The objective is to simulate and determine: - Shaft deflection under the weight of the discs and other components - Stresses caused by bending and motor torque - Combined bending + torsional stresses - Shaft deformation and safety factor during normal steady-state operation - Loads and stresses during motor start-up and stopping, including maximum transient torque The simulation should represent the actual shaft supports/bearings and the distribution of the discs along the shaft. Phase 2 – Design and comparison of alternative shafts The objective is then to evaluate alternative materials and shaft geometries in order to reduce weight while improving mechanical performance. For each relevant solution, I would like to compare: - Maximum shaft deflection - Maximum stress / strain - Torsional deformation - Safety factor - Weight - Performance during start-up, steady-state operation and stopping The new design should have lower deflection than the existing stainless-steel shaft and sufficient safety margin under all operating conditions. I can provide the 2D scheme, dimensions, material information, disc weights, bearing positions, rotational speed and operating conditions. Expected deliverables - FEA results for the existing shaft - Comparison of relevant alternative materials/designs - Deflection, stress and safety-factor results - Short engineering report explaining assumptions, boundary conditions and conclusions - Simulation files

Hi Your project is a strong match for my background in mechanical engineering FEA and design optimization I would first validate the existing shaft using the real bearing positions disc loads motor torque and startup conditions then use the results to develop a lighter design with lower deflection and a reliable safety margin My workflow combines analytical shaft calculations with ANSYS FEA so the final recommendation is based on both engineering theory and numerical validation rather than simulation alone! You will receive the existing shaft assessment the optimized alternatives a clear comparison of stress deflection torsion safety factor and weight plus the simulation files and a concise engineering report :)

I can handle this using ANSYS Mechanical FEA with realistic bearing supports, distributed disc loads, combined bending + torsion, and transient loading. I’ll analyze the existing stainless-steel shaft, identify the critical load case, then compare alternative materials and shaft geometries based on stress, deflection, torsional deformation, safety factor, and weight. I’ll provide the optimized recommendation, FEA files, and a concise engineering report. Can you share the shaft dimensions, bearing locations, disc weights/positions, motor torque and start/stop time? Best regards, Arati M.

Hello, I am Muhammad Javed, a Mechanical Engineer with more than 10 years of experience in mechanical FEA, shaft design, stress analysis, and mechanical optimization. I can perform a complete FEA assessment of your existing stainless-steel shaft, accurately modeling the actual bearing supports, disc positions, component weights, rotational speed, and operating conditions. The analysis will cover bending loads, motor torque, combined bending/torsional stresses, deflection, deformation, and safety factor during steady-state operation, start-up, and stopping, including transient torque where applicable. For Phase 2, I can evaluate alternative shaft materials and lightweight geometries and compare each option against the existing design based on maximum deflection, stress/strain, torsional deformation, safety factor, weight, and operating performance. The optimized shaft will be selected to achieve lower deflection while maintaining an appropriate safety margin under normal and transient loading. I will use your actual shaft configuration and load distribution rather than relying on overly simplified assumptions. Deliverables will include FEA results, alternative design comparisons, simulation files, and a concise engineering report covering assumptions, boundary conditions, results, and recommendations. I am ready to review your 2D scheme, dimensions, disc weights, bearing positions, material data, speed, and operating conditions and begin immediately.
