Karlstad University, MSc. in Mechanical Engineering with specialization in Materials Engineering

Modules: Mechanical properties of the materials, alloying elements and composition, microstructure, Tribology, Fractography, wear, etc.

Investigation of various mechanicl component, i.e. journal bearing, roller element bearings, shafts, gears, etc. to identify their mechanical properties, production method, heat treatment, etc.

Root Cause Analysis of fracture and failure of the machine components.

Simulation and Modelling: Matlab

Machine Design: Pro-E • Finite Element Analysis: Stress / strain analysis in Abacus and Matlab

Machine diagnostics: Machine vibration measurements and analysis to discover defects and identify the faulty machine components.

Thesis: Tribology ‘’Formation of protective lubricious oxide layers on the surface of nitrogen alloyed steels in self- mated sliding’’ The experiments were held at the Karlstad university on three different PM tool steels, manufactured by UDDEHOLM AB, Hagfors, Sweden. In this project I examined the influence of lubrication condition and normal 2001-2003

1998-2001

load rate on tribo-layers and wear rates over the contact surface.

Materials Lab: SEM, TEM, OM, Profilometer, Stress/strain analyzer, Vickers Hardness tester.

Azad University of Tehran, Ba. in Mechanical Engineering with specialization in heat and fluids

Modules: Fluid mechanics, Thermodynamics, Heat transfer, Machine design, Structural analysis.

Electronic simulation of the pools of a fish farm: The purpose was to simulate the pools and the control valves to control the water level in the pools and the valves to achieve the optimum stability and control of the pool. I used electronic capacitors instead of real pools and variable resistors (control volume) as control valves and run the test using an oscilloscope.

A pneumatic machine consist of a Rotary table, two guided drives (vertical and horizontal) and a radial gripper. Azad University of Tehran, Associate degree. Mechanical Technician in Automotive Industries

Modules: Fuel systems, Power units (engine), Power transmission, suspension.

WORK EXPERIENCE

Feb. 2019- Present

Aug. 2011- Jan. 2019

Development Engineer at SKF AB

Spherical Roller Bearings

- Silent bearings for special applications:

To improve in Noise and Vibration level in SRBs, several physical specifications of the bearings were tested to identify the impact of each individual feature on noise and vibration. These target features were surface texture and surface roughness of each component, internal clearance, mechanical specifications of the lubricant, lubrication quality, lubricant filling degree.

- Wind turbine SRB Development:

Investigation and technical solution for excessive guide ring and roller wear.

- Root cause analysis of worn and fractured components: Fatigue, high friction wear, fretting, Brinelling and electric arc are the common causes for bearing failure. Root cause of these phenomena in different application are not the same. Identification of the root cause needs special analysis for each case to be able to define the suitable solution.

- FMEA & DFMEA:

Failure mode analysis and design failure mode analysis for modified bearings

Project Engineer at National Oilwell Varco Norway

- Product Design and Development:

Offshore lifting & handling (Offshore and AHC Cranes and Winches) under DNV, ABS, and NORSOK regulations. The work included CAD design, structural analysis, Production control, FAT and SAT. -Component failure Root Cause Analysis: Planetary gears, gear wheel and pinions, hydraulic cylinders, hydraulic pumps and motors, bearings, structural July/2005 - August/2009

steel plates.

- FMEA & DFMEA:

For new products during and after design process.

- Research & Development:

After the bearings of an ultra size machine crashed drastically and unexpectedly, the Root Cause Analysis was to be held to understand what defect, why and how was initiated and developed in such a short time which caused the bearings to crash after passing less that 20% of the calculated life times by the vendors (SKF and FAG). Due to my material

engineering back ground, I got the chance to role in this regard. The initial visual inspections of the bearings indicated False Brinelling caused by Fretting and later by the lab investigation held by DNV (Det Norske Veritas) in Norway we found the indications of Fretting Fatigue as the main cause. Following this situation the company decided to find a reliable Condition Monitoring method among the existing methods in the market to prevent the catastrophic failure of the similar machines where I worked as the main planner and performer of the tests and developments of the project.

To evaluate the performance and the precision of the different bearing damage detection methods and compare them to find the optimum method and set ups, I designed and constructed a lab test rig including 3 different spherical roller-bearings. Two separate mechanisms were designed to apply variable axial and radial loads to the shaft. Two load-cells were used to measure the load rates separately.
