Koray Erdem

Mechanical engineer working at the intersection of machine design, simulation and manufacturing drawings. I take parts and assemblies from SolidWorks into ANSYS (structural, thermal, modal, explicit/Autodyn, CFD) and COMSOL, then close the loop with shop-ready documentation.

Most of my work sits on industrial machinery, energy hardware and defense structures: plastic extrusion and press-brake equipment, shaft and torque checks, thermal and flow models, and high-rate dynamics when the load case demands it. I work remotely, scoped by the deliverable — model, analysis memo, drawing pack.

Mining Facility Project

The bunker, conveyor, drying tank, and ventilation stack were modeled using SolidWorks. Load calculations regarding the mineral material to be processed were performed using Ansys, and component thicknesses were optimized. Motor power and shaft specifications were determined based on torque requirements, and chain selections were made. Bearing placement and sizing were calculated based on weight.

Steel selection was determined through thermal analysis of the dryer. Finally, production commenced, and the facility was installed.

Food Production Facility

Facility Installation Stages

Factory measurements were taken.

Column and floor load calculations were performed.

Silos were selected based on the volume of food to be produced.

Augers for material flow and their required motor powers were calculated.

Hopper positions were adjusted to ensure proper food flow.

An elevator system was designed, with motor power calculated based on weight and rotational speed.

3D models were created using SolidWorks and exported to AutoCAD in DXF format for laser cutting.

Pipe lengths and shaft thicknesses were calculated based on the discharge rates of the augers.

Finally, motors were selected according to the load requirements of the mixers, and production commenced.

Vehicle Aerodynamics

Microchip Cooling Calculations

Shaft Sizing

Lift and drag analyses were performed for a vehicle traveling at constant and variable speeds, and its road-holding characteristics were calculated based on its weight. The impact of airflow on the vehicle's aerodynamics was also calculated in relation to its weight.

FEA - ANSYS (CFD)

Microchips generate high heat during operation. They require cooling. Fan power and blade diameters were calculated based on this cooling load, and the fans were sized accordingly.

CAD - SOLIDWORKS

FEA - ANSYS (Static Structural - CFD)

Engineering calculations for the shafts were performed based on the gears used and the motor torque, and stress levels corresponding to the loads were determined through simulations. Through optimization, the shaft thickness was finalized based on the safety factor, and production proceeded using these optimal dimensions.
