Article Citation - WoS: 19Citation - Scopus: 22Oscillatory Time-Frequency Concentration for Adaptive Bearing Fault Diagnosis Under Nonstationary Time-Varying Speed(Elsevier Sci Ltd, 2023) Li, Yongbo; Fu, Hao; Feng, Ke; Li, Zhixiong; Peng, Zhike; Saboktakin, Abbasali; Noman, KhandakerBeing a promising post-processing solution, application of time-frequency concentration (TFC) suffers in an adaptive fault diagnosis scenario due to non-adaptive extraction of bearing fault signature from noise-associated vibration signals under nonstationary time-varying speed. Aiming at solving this problem, a novel method called oscillatory time-frequency concentration (OTFC) is proposed by oscillation based adaptive extraction of time varying bearing fault signature with the help of tunable Q factor wavelet transform (TQWT). OTFC can effectively suppress unwanted noise while adaptively reveals the time-varying fault characteristic frequency (FCF) and corresponding harmonics with excellent readability. Two distinct numerical simulations and experimental case studies have been utilized to verify the performance of the proposed OTFC. The results show that the proposed OTFC not only performs better than the conventional TFC method namely synchrosqueezing wavelet transform (SST) but also shows superior performance than traditional continuous wavelet transform (CWT) and advanced TFC method namely multitaper synchrosqueezing wavelet transform (MST).Article Aerospace 3d Textile Preform Analysis: Experimental and Mesomodeling(Polish Society of Composite Materials, 2023) Saboktakin, Abbasali; Safaei, H.For the purpose of predicting how textile preforms affect the quality of the composite material and its performance, the stitched textile preform must be characterized. Experimental compaction analysis and finite element analysis of textile preforms are the main subjects of this paper. The formability parameters of a preform can be changed by the stitching process, according to research on the mechanical properties of preforms conducted during compression testing. The load-deformation response, which is depicted in detail, had the greatest influence on preform deformation. Less fiber bundle undulation in the plane direction and more stitching thread undulation in the thickness direction were observed during compression of the stitched preform, whereas the stitching thread improved the resistance of the preform to compression loading. © 2023, Polish Society of Composite Materials.

In this paper, the particular specifications and designing factors that should be met by rocket engine fuel pumps are demonstrated, and a comparative study is formed on the suitableness of all the necessary kinds of pumps to be used with rocket engines and their applications. Furthermore, the paper describes low cost and high-performance pump technology. This new piston pump has been improved for space applications. Depending on the type of body of this pump, its various parts should be evaluated at the desired pressure and temperature as well as the speed of fluid handling, leakage from the body, and the strength of the parts. Our review results are expressed to give complete awareness of different situations in space rockets.Article Citation - WoS: 2Stitched preform characterization for satellite structures(Springer Heidelberg, 2023) Saboktakin, Abbasali; Safaee, Hossein; Spitas, Christos; Kalaoglu, FatmaCharacterization of the stitched textile preform is required for the prediction of textile preforms forming in the fabrication of composite structures for aerospace applications. The behavior of the preform in compression during resin injection into the preform is one of the critical issues in achieving a high-quality composite for space structures. This paper concentrates on the experimental and finite element analysis of compaction for textile preform. The investigation of the mechanical properties of preforms during compression tests revealed that the formability parameters of a preform can be altered by the stitching process. The load-deformation response, which is depicted in detail, had the greatest influence on the preform deformation. Compression of the stitched preform resulted in less tow undulation in the plane direction and more stitching thread undulation in the thickness direction, while the stitching thread stimulated the preform to endure more pressure. The results provided more detailed insights into the effects of compaction on other properties such as permeability and composite mechanical behavior, which is based on the internal geometry of 3D textile preforms.Article Reusable and Low-Cost Space Rocket Enginewith High-Efficient Propellant Pump(Bulgarian acad sciences, space research & technology inst- srti-bas, 2024) Saboktakin, Abbasali; Monjezi, MohammadSpace propulsion mainly uses reciprocating pumps that are fully integrated with small-scale applications. In this paper, the specific specifications and designing factors that should be met by rocket engine fuel pumps are demonstrated, and a comparative study is formed of the suitableness of all the necessary kinds of pumps to be used with rocket engines and their applications. Furthermore, it examines a piston pump intended to refuel the liquid fuel nozzles. Due to the performance of this pump, different parts and its performancehave been evaluated. The design of the pump is discussed such that after completing the design steps according to the pump performance, a numerical solution of the stress and strain applied on the inner wall of the cylinder is performed according to its performance under internal pressure. Then, considering the consistency of the body material and the same pressure and heat applied to the cylinder and piston, a sample of the cylinder and piston is analyzed in finite element modelingtechnique and the modeling results obtained from the simulation are presentedArticle Citation - WoS: 1Citation - Scopus: 1Vibrothermography Technique for Non-Destructive Testing(Springer, 2025) Saboktakin, A.Ultrasonic thermography, also known as sonic infrared imaging, is a promising technique that excites ultrasonic elastic waves and is commonly used in the automotive and aerospace sectors to detect and evaluate flaws in solid specimens. This method employs ultrasound-generated thermal waves to enable defect-specific imaging. The present paper reviews new findings and significant advancements in ultrasonic thermography. The paper is structured as follows: an introduction to ultrasonic thermography is first provided, followed by a discussion on improvements made to enhance the reliability of vibrothermography. Next, an analytical study of different excitation methods and structural parameters is presented, along with an examination of the effects of various excitation parameters on the system's performance. Subsequently, a vibration monitoring method is introduced. Finally, the key causes of heat generation in this technique, along with analytical approaches, critical factors, and limitations in vibrothermography, are discussed.
