Information

Iryna Matsiuk, graduated from the State Mining Academy of Ukraine with honors, 1996, specialty "Mineral Enrichment". Qualification – "Mining engineer of ore dressing".  

After graduate studies, she defended her Candidate's thesis on the topic: "Justification of the waste-free technology of processing lignite sludge of briquette factories" (05.15.08 - Mineral enrichment, 2006, DK No. 36690). The dissertation proposed a new technology for processing waste from briquette factories (sludge and dust), which helps to obtain additional purified water for technical needs.

Iryna Matsiuk has been working at the Department of Fundamentals of Mechanism and Machine Design since 2004. During this time, she has achieved a high professional level, and acquired experience and pedagogical skills. Positive results in work and activity in the implementation of scientific events of the department and faculty, high research and methodological level of teaching and motivation are also noted.

In 2011, she received the certificate of an Associate Professor of the Department of Fundamentals of Mechanisms and Machines (Certificate DC No. 26891, date of issue 01.20.2011, Attestation Board of the Ministry of Education and Culture of Ukraine No. 3/02-Д).

Now, Iryna holds the position of Associate Professor of the Engineering and Generative Design Department (which is the new name of the department after renaming).

The disciplines taught include:

·     Theory of mechanisms and machines;

·     Details of machines;

·     Technical bionics / Biomimetics or biomimicry;

·     Engineering graphics;

·     Applied computer graphics;

·     Technologies of 3D prototyping;

·     Industrial design.

When teaching these disciplines, Iryna uses personal experience in engineering and scientific research activities and modern graphic and mathematical computer software. In teaching, she also uses the following software products: Autocad, Autodesk Fusion 360, Autodesk Inventor.

She has done the course "Transition from classic CAD to cloud Fusion 360" at the Autodesk Authorized Training Center and received a certificate for the Fusion 360 new software product (certificate number EM303884096129684666892 dated April 30, 2020).

She has a B2 English proficiency certificate.

Scientific work.

She was engaged in the following scientific areas:

1. Substantiation of rational drive parameters for reliable operations of heavy-loaded mechanisms.

The purpose of the study is to evaluate the influence of driven crank parameters on the location of different sets of a mechanism with the fourth-class structural group.

An algorithm of defining a zone of positioning the rotational center and length of a crank is determined for plain mechanisms of the fourth-class structural group. It has also been found that probability of spontaneous transition from one assembly to another closely-spaced assembly in heavy-loaded mechanisms can be reduced significantly by choosing the appropriate rotational center of a crank.

2. On applying high-class mechanisms of heavy-loaded machines.

The work studies possible variants of assemblies of the fourth class Assur group as a component of a jaw crushing machine and evaluates their impact on operation of the machine runnability. 

The originality of the work involves defining the number of possible assemblies of the fourth class Assur group. For the group under consideration, it has been established that the maximum number of assemblies equals four.

An algorithm of finding a zone of possible positioning of a driven crank of a crushing mechanism is suggested, which allows influencing the remoteness of two closely-spaced assemblies.

3. Some aspects of synthesis of linkage of complex structures

The work studies possible variants of assemblies of the fourth class Assur group consisting of four links and evaluates their impact on operation of the mechanism containing this Assur group.

It has been established that in the planar of the fourth class Assur group the number of possible assemblies does not exceed two. Very close mutual arrangement of assemblies is possible. Position functions of mechanisms with different assemblies differ from one another.

Now she is engaged in the following scientific direction:

Ways to reduce the weight of machine-building industry parts.

The study presents the results of work on changing the weight of machine-building industry parts.

Two variants of the solution for the problem are considered. In the first variant, it is proposed to remove the unloaded areas of the part to the constructive minimum. The other solution involves the replacement of the unloaded areas of the parts with non-metallic inserts.

Both variants are based on the method of topological optimization of parts. The Fusion 360 software product (Shape Optimization option) is applied as a tool. A 3D models of machine-building industry parts was developed from which unloaded areas were removed followed by topological optimization of the parts carried out, which made it possible to reduce the mass significantly.

A promising direction for reducing the metal consumption of machines, in particular the machine-building industry parts, is the search for optimal design solutions.
