Senior mechanical engineer (15+ years) providing CAD design, structural FEA, fatigue/durability analysis, and multibody dynamics simulation — backed by OEM-level design responsibility (currently Technical Director) across automotive, commercial vehicle, and agricultural machinery programs. What I deliver: - CAD (SolidWorks, CATIA V5) – weldments, sheet metal enclosures, fabrication-ready drawing packages, revision-controlled design support for capacity overflow and ongoing design work - Structural FEA – static, thermal, contact analysis with clear boundary conditions, mesh convergence, and standards-referenced reporting (ANSYS, CalculiX, PrePoMax) - Fatigue & durability analysis – S-N/E-N methods, damage accumulation, load case definition for welded structures and dynamically loaded components - Multibody Dynamics (MSC Adams) – full-vehicle and subsystem simulation, suspension kinematics, hardpoint optimization, target-setting - GD&T & tolerance stack-up analysis (ASME Y14.5, Worst-Case/RSS) for manufacturability review - Independent second-opinion review for existing analyses or designs before production commitment Available for fixed-scope analysis, short-term CAD/CAE capacity support, and design verification work. Happy to clarify scope before starting.
