STUDDY OF THE RESONANCE PHENOMENON
IN ALTERNATIVE CURRENT CIRCUITS
In general, the sources of electrical energy that supply electrical
circuits provide them with both active power, necessary for various uses, and
reactive power, corresponding to the variation of the energy stored in the
electric and magnetic fields of the network. In certain particular cases, it is
possible that while energy is accumulated in some of these fields, in the other
fields the energy decreases by an equal amount, the electric and magnetic
fields mutually supplying the necessary energy, so that the energy exchange
between the source and the fields in the circuit is zero at any time and –
correspondingly – the reactive power supplied by the source is also zero.
Although the circuit has reactive elements, it will absorb only active
power from the source. In this case, it is said that resonance phenomena occur
in the circuit

29-23 STUDIUL DIN PUNCT DE VEDERE DIDACTIC AL MECATRONICII

Această intrare a fost publicată în 2016 Volumul 29 și etichetată Liliana DACHE la de

STUDY IN TERMS OF TEACHING MECHATRONICS
To keep up with technology mechatronics education system had to
adapt quickly. In 1984, an international conference on education in engineering
technology held in Germany, K.Yamazaky, professor at Toyohashi in Japan,
launched the idea that, Mechatronics is a major need for European research
and education programs”.
Universities have had to align educational programs so that
knowledge taught may include requirements of a specialist in mechatronics.
This paper addresses a study in terms of teaching mechatronics.

Această intrare a fost publicată în 2015 Volumul 27 și etichetată Liliana DACHE la de

KNOWLEDGE TRIANGLE:
EDUCATION-RESEARCH-INNOVATION
In the context of the transition to the knowledge society, the European Union aims to insure framework for smart, sustainable and inclusive growth. The society based on knowledge and innovation involves integration of new technological infrastructures, research processes, development and innovation, as well as the educational, contributing directly to the development of intellectual capital, the main resource of current society.
This paper presents the relationship between the three sides of the knowledge triangle, education, research and innovation and interdependence between them.

MECHATRONIC PLATFORMS
FROM SIMPLE TO COMPLEX
This paper presents the mechatronic platforms as an ideal base for
training, education and research mechatronics, to support the process of
retraining and vocational guidance in accordance with the requirements of the
European Union trades. They fail to satisfy the needs of a growing number of
products and industrial processes involving the use of mechanical and
electronic components as well as control software design and development.
Mechatronic platforms provide the conceptual approaches, methods
and tools to achieve the objectives of education operating and development of
educational technologies.

DC MOTORS CONTROL BY PULSE WIDTH
This paper proposes a modern method of adjusting the rotation speed
of a DC motor. Development of DC static converters will allow adjustment of
DC engine revolution by variation of supply voltage variation; you can get
through that varies the voltage.
Study of pulse control of a DC motor is achieved by pulse width
variation obtained by using static converters.
For a clearer example of the link between the setting of a gear and an
automatic system will give an example of such a system by designing and
establishing the necessary characteristics of the components of the schema
which contains the control of impulses modulation.
