Samson Z E R I H U N Damtew | University of Trento (original) (raw)
My name is Samson Zerihun, born & raised in Ethiopia. I'm a holder of MSc. in Mechatronics Engineering (Robotica) from University of Trento - Italy, & BSc. in Mechanical Engineering from Mekelle University-Ethiopia. Currently, I’m the Dean of Engineering college & work as a Lecturer in Wollo University – KIoT (Kombolcha Institute of Technology), at the Department of Mechatronics Engineering.
I have a good understanding and excellent learning ability starting from my childhood and thanks to God I even won a Scholarship in Italy (“Borse di Studio”) from “Opera Universitaria” in pursuing my graduate study and finshed with good ranking – I even won a Merit Award (“Premi di Merito”) from my University for my successful achievements. At this point in my development, I’m ready to utilize my studies and work experiences as a valued Multi-skilled Engineer and pursue my career in a related job opportunities in industrial and or academic research spectrum.

Biodegradable ber-reinforced composite materials are one of the prime attractions to the researcher due to their easy availability and low cost. During drilling of these Natural Fiber Reinforced Plastic composites (NFRP), delamination and surface roughness are the problems encountered, which are to be minimized to get better output by adopting di erent cutting conditions and tools. is work aims at the drilling of naturally available coir ber-reinforced composite materials by using a multifaceted drill bit. Material thickness, spindle speed, feed rate, and multifaceted bit diameter are input against the output delamination. After modeling of the output result, a sensitivity analysis tool is introduced to rate the input factor to minimize delamination. SEM images are used to analyze the fracture morphology.

Indeed these vehicles have been delivering a great service for the most peoples of the regional cities of our country, but there is also a great fatality rates on accidents caused by such vehicles. Among the accidents most of them are rollover accidents on these vehicles without crashing with other vehicles. So there was a great deal of problems needed to be solved on stability and maneuverability of such vehicles. This thesis study is mainly focused on designing a three wheel steering system so that the stability and maneuverability of three wheeled vehicles will be enhanced. The design was achieved by designing new three wheel steering system which can be implemented on three wheeled vehicles by some new component designs and other remaining component modifications. This was done by using SolidWorks and ANSYS software. There has been a reduction of turning radius of these vehicles from 2880 mm to 1471.79 mm and also increasing the maneuverability of the vehicle from 2 to 5, so that the vehicle can turn with narrow roads around crowded areas of the cities. The main thing I have done was connecting all the three wheels by a mechanism so that they can turn accordingly and the rear wheel turns opposite to the front so that it can cover shortest distance to turn around in crowded areas. The system I have designed is a better steering system than the existing one in a ways such as easy and economical to manufacture, it has better maneuverability suitable to operate and does not affect the appearance of the existing vehicle body.
