Approches in Mechanical Engineering

Ancient books show that mechanical engineering in ancient Persia has been a very prosperous and industry men have been familiar with it. Historical books available in this area confirm this.

But by attention to the deep history of mechanical engineering science in Iran, has mechanical engineering education in this country, been leading? To answer this question and achieve this goal should pay special attention to the need for change in engineering education.

At the beginning, mechanical engineering education were summarized in workshops and experimental and laboratory lessons. Engineering graduates to be trained to be able to work in the industries immediately   and to resolve the industry needs. The Masters were experienced ones in industry and a very small part of their activities compromise research. 

Engineering education did not meet the needs of society, gradually.     So, the process of change in engineering education and research to implement new innovations reach the super accelerated. Changes in educational systems should be applied in many large educational institutions are being conducted. Here, these issues can be briefly stated as follows:

۱ – Factors associated with the learning environment

۲ – Factors associated with university-industry collaboration

۳ – Factors associated with the content of training courses in Mechanical Engineering

۱- Faculty and students must b ​​aware of the importance of practical activities. In addition to knowledge of engineering education, engineering students also must learn applied engineering. Student must be a way to strengthen to find the innovation capabilities, vision and creativity. Giving high marks to students and to raise average scores can have a negative impact on the quality of education and in fact, the desire to strive to improve the situation of low student motivation and destroys the outstanding students.

۲- Closer relationship with industry and other organizations, enrich the academic training, especially mechanical engineering education. Also training has an impact on student’s education. Faculty stuff involvement with industry is also very important issues which could lead to work of researches on significant problems of industry.

۳- The course needs to be updated based on new technologies and also brought new subjects and also courses must be updated constantly.

Till year ۱۳۷۹ Supreme Council for Planning Council under supervision of the Ministry of Science was responsible for updating the curriculum of academic disciplines. This effort in the Mechanical Engineering resulted in Course syllabus development in the tendency of heat and fluid and solid design in1376 and in the tendency of manufacturing and production in 1368.

Till today, Mechanical engineering education is to act within that syllabus. From 1379 Planning Board of university are responsible of this duty. In terms of contents of courses, courses in Iranian universities are nothing short of world universities. But it should be noted that professional courses in other countries are commonly taught with a laboratory course.

The first goal of the University of Applied Science as their name implies, is training of efficient labor for the industry to work. As what we write above, can be seen that current Perspectives in Applied Science University can be directed to the correct position and motion to solve all these problems.

As the most students are from people working in the industry, entering of these students to these universities is a factor is which connected University with industry. Students can take steps towards solving their industrial problems, although short ones. However, it should also be noted that these universities should be very careful that, due to being technical students, do not forget to assessment them in theoretical courses, correctly.

But in the field of mechanical engineering and automotive trends in particular, due to the comprehensiveness and generality of engineering expertise in this field, we can say that graduates in these disciplines can be easily related to other fields of industries. All courses are specialized to general trends in fluids and solids, are considered in this trend. But here there is a fundamental problem in this emerging trend of mechanical engineering. Students studying in this field due to the technical nature of their jobs, usually are weak in the basic mathematical and theoretical courses, so by considering to this, the students this trend should be strengthened at the beginning of courses by offering more primary mathematical and theoretical courses, and by providing Courses with more sessions than which exist for trends fluid and solid mechanics, led them more and better scientific professions. In other hand, as what we said above, Topics considered in this trend, in addition to the usual courses in Fluid and Solid Mechanics trends, compromise a number of specialized courses specific to this field. So regards to these articles it is essential to note that for example, a course like Dynamics which is offered as 4 units course and in three sessions per week in trends of fluid and solid mechanics, in automotive trends is offered as 2 units course in 1 sessions per graduate students o this trends by considering to proposed units units has expertise in fluid mechanics and heat transfer. By these professions they specialize in working in power plant and oil industry. In other hand, they are equipped for working in industry of rotary machines which encompass large part of today industry. Also, they gain some profession about the science of materials and could work in metal forming and mining industry.

About research in field of heat transfer, combustion, high efficiency combustion, engine of vehicle is the world of unknowns that can provide the possibility to do a lot of research work. Today need of lower fuel consumption and reduce pollution always been a challenge in order to raise the combustion efficiency, use of new technologies such as fuel injection, check the thermodynamic combustion cycle of  engine, exergy analysis, the use of alternative fuels and thousands of other field has led the effort of scientists in the of mechanics.

Materials science is major challenge in research activities for automotive trend of mechanical engineering. The use of composites and nano-composites in the body and engine components in order to raise efficiency and lower vehicle weight provided other areas for research, too. The work about alloys used in construction of automotive cylinder and also use of carbon fiber to build the chassis and body of cars, are examples of these tasks which result in numerous ISI papers and commercial use of them in automotive industry.

As the engine is a rotational system provides a world full of questions for research work, which could lead to a lot of research in this new field. Considering to Fatigue properties of vibrational properties of automobile and engine components that are under fatigue load and totally vibration Analysis of cars has been field of lot of new researches. Also, many studies in the field of acoustic engineering have always been performed. An example of application of acoustic science in the vehicle is use of Muffler exhaust of cars. Optimize the acoustic performance of Muffler can be highly effective in vehicle performance. Reduce noise at high speeds as well as other areas of mechanics in the automotive industry are challenged.

In the field of metal forming science, Automotive Engineering provides a world of questions that the answer of them can respond to every research in the science of mechanics, whether in the plastic or elastic zone of materials. For example production of h body of vehicle applied the science of sheet metal forming, pinion gear of starter of cars produced by forging method. That each of these types of production processes in terms of the residual stresses, thermal stresses, surface residual stress, surface quality and etc. must be reviewed.
