Scientific projects

2012–2014 – Researcher in the project “Study of Multi-Loop Lever Mechanisms Considering a Set of Quality Criteria”, Joldasbekov Institute of Mechanics and Mechanical Engineering.

2015–2017 – Researcher in the project No. 5762/GF4 “Development of a Methodology for the Formation of Modifying Multicomponent Nanostructured Surface Complexes with Special Properties to Improve the Operational Characteristics of Critical Engineering Products” within the Grant Funding Program for Scientific Research for 2015–2017, Satbayev University.

2020–2022 – Principal Investigator of the project AR08082125 “Development of a New Design of Drive for Rod Pumping Units for the Oil and Gas Industry”, Joldasbekov Institute of Mechanics and Mechanical Engineering.

2021–2023 – Senior Researcher in the Program-Targeted Project No. O.0971 “Development and Implementation of Medical Robots and Intelligent Systems in Kazakhstan to Improve the System of Diagnosis and Treatment of Patients under Pandemic Conditions”, Joldasbekov Institute of Mechanics and Mechanical Engineering.

Under her supervision, the research group developed a universal software package for the calculation and optimal design of new drives. The team conducted analysis and optimization of sucker rod pump units and studied balancing modes, resulting in a new mechanism design for the pump unit. Design documentation (PKD) and an experimental prototype were developed.

The applicant’s scientific activity program includes:

development of algorithms and core software for calculating a new pump unit design;

development of a universal software product for the calculation and optimal design of new drives;

preparation of design documentation and a pilot-industrial prototype of the pump unit;

development of measures to minimize total manufacturing costs of new equipment;

design of an experimental robot prototype for disinfection and wet cleaning of premises.

2023–2025 – Principal Investigator of the program BR21881957 “Development of Deep Processing Technology and Vacuum Sublimation Drying Equipment for Mare’s and Camel’s Milk”, Joldasbekov Institute of Mechanics and Mechanical Engineering.
