Summary:

I spent 7 years in industry, from 1979 till 1986, as Design Engineer, Senior Design Engineer, Quality Control Supervisor, and ultimately Project Leader.

Incubator & Hatcher Machines Mfg.

Company I was working as a Director of Engineering at the Jojiran Incubator & Hatcher Machines Manufacturing Company. Manufacturer of Incubator & Hatcher Machine, Model 1000, to produce 1000,000 one day old chickens per month.

Heave Duty Truck Mfg. Company

My main industrial experience was gained from Volvo-Iran Kaveh Heavy Duty Truck Manufacturing Company (VIKC), manufacturer of flat-bed & low-bed heavy duty semi-trailer chassis, fifth wheel, fifth wheel coupling pin, leaf springs, suspension & equipment components, and tractor-trailer axles & spindles for all types of light and heavy duty vehicles, as well as those for military and agricultural implement industries. Highlights of my tasks and responsibilities within the company include the following:

• Design Engineer: Semi-trailer Chassis Design Division, March 1979 –April 1980.

Research

My main research contribution over these periods has been concentrated on:

• Vehicle Structural Integrity (strength & durability analyses).
• The international Codes & Standards, applied mainly to structures & components design.
• Modification and development of the National Codes & Standards on the basis of several factors such as: domestic requirements, quality metal fabrication, road surface conditions, cost estimate, and etc.
