I am building a miniature voice-coil actuator and I need a seasoned mechanical engineer to design a flat stainless-steel flexure (also called a spider) production-ready for photochemical etching. The priorities are clear: long-term durability comes first, so every decision—geometry, thickness, fillet radius—should drive stress down to safe margins while still giving me an axial travel of about ±5 mm with excellent self-centering and minimal tilt. Your core task is design optimisation; material selection and other technical advises are welcome., but the optimisation itself must lead. Key parameters you will start from • around 50 mm outer diameter (we can configure this based on stress analysis) • 19.5 mm clear centre hole • Spring stainless, 0.05–0.10 mm thick (confirm best gauge) Analysis focus A concise static FEA that shows stress distribution and stiffness, with clear evidence that the design minimises peak stress while keeping the desired stroke. Deliverables 1. Final 2-D flexure geometry in DXF and STEP format, ready for photochemical etching. 2. FEA report (figures, summary tables, solver set-up). 3. Recommended material grade/thickness with reasoning. I value examples of your previous work on compliant mechanisms, loudspeaker spiders, precision stages or similar spring structures, so please include anything comparable. If you enjoy squeezing every micron of performance from thin steel while keeping it indestructible, let’s talk. Need support till the end, when we have tried different iterations and confirm that our needs are fulfilled.

Hi, I’m a Mechanical Design Engineer with 7+ years of experience in mechanical design, structural analysis, and manufacturing-oriented product development. I can assist with the complete design and optimization of the stainless-steel flexure, focusing on durability, stress reduction, self-centering performance, and manufacturability for photochemical etching. I can provide: 1. Flexure Geometry Development & Optimization 2. Static FEA for Stress, Deflection & Stiffness Validation 3. Material & Thickness Recommendations 4. DXF, STEP & Manufacturing-Ready Deliverables 5. Design Iterations Until Performance Requirements Are Achieved 6. Engineering Report with Stress Distribution & Design Rationale My approach will focus on minimizing peak stress while maintaining the required ±5 mm travel, good axial guidance, and minimal tilt throughout the operating range. I primarily work in SolidWorks and engineering simulation workflows and focus on creating practical, manufacturable designs supported by analysis rather than trial-and-error. I’m happy to support the project through multiple iterations until the final design is validated and meets your performance targets. Regards, Shivam Jha
