Metal matrix hybrid nanocomposites are widely used due to their good strength and wear resistance properties. Because of its light weight and excellent mechanical properties, the ZA-27 alloy is used in industrial and automobile applications. The research article is focused on manufacturing of ZA-27 matrix material reinforced by 1.5 wt. % of Aluminium Oxide (Al2O3) and 0.5 wt.% of Molybdenum Disulphide (MoS2) hybrid micro and nanocomposites by using stir casting followed by ultr...

This study aims to explore a flight simulator system for multi-axis motion control, focusing on operational safety and data transmission speed. New concepts in mechanism design, multi-axis motion control, and control system design are presented.

The system's effectiveness was confirmed through testin...

The Flux Switching Motor (FSM) finds wide applications across various industrial and residential domains. Enhanced motor performance correlates directly with an increase in average torque (Tavg), while a rise in torque ripple (Tripple) leads to heightened instability, particularly evident at higher speeds. To mitigate the impact of these factors on miniature FSM operation, this study conducted simulations and analyzed the influence of rotor geometric parameters on design model p...

This study compares two metrology-grade methods for measuring squareness errors in three-axis machine tools: the Swing Round Method (SRM) and the Reversal Method (RM). The experiment utilized a holeplate with standard size transfer functionality as a geometric error analysis reference, comparing the measurement results of these two methods. The experimental results show that the measurement differences between the two methods remain consistently within 1 arcsecond, meeting the ...

With improvements in quality of life, the demand for high-quality safety glasses and sunglasses has increased. Prismatic refractive power is a crucial aspect of eyewear testing. According to ISO 18526- 1:2020, this testing procedure involves focusing an inspection beam on a scale target 2 m away after it passes through the glasses. Subsequently, the prismatic refractive power of the lenses is determined by observing the displacement of the focal point. Nevertheless, human observ...

This study focuses on the dynamic characteris￾tics of a high-precision surface grinding machine. Modal analysis using Finite Element Analysis (FEA) was employed to determine the fundamental frequen￾cies of the structure. An Experimental Modal Analysis (EMA) was conducted to validate the vibration char￾acteristics and prevent resonance. Modal analysis con￾firms primary and secondary natural frequencies of 68.2 and 134.3 Hz, respectively, with a discrepancy of <10% compared to experiment...

The long-term operation of ball bearing leads to the deterioration of lubrication condition, resulting in starved lubrication, which intensifies the wear of rolling body(RB). Accurately identifying this fault has a significant impact on bearing condition monitoring. In this paper, the wear of RB was quantified by diameter difference, and the friction between components was considered, the fault dynamic model of RB wear under the condition of starved lubrication was established....

The method of setting the boundary conditions of the piston temperature field is determined. Structural analysis software is utilized to conduct a numerical analysis of the temperature and stress fields of the piston. The quality loss model examines the correlation between temperature and piston quality loss. The research and analysis can provide a more in￾depth understand...

To solve the current problem of a single magnetic coupler speed regulation method, a permanent magnet (PM) rotatable magnetic coupler structure is proposed, named magnet-rotating-type axial magnetic coupler (MAMC). The MAMC can be speed regulated in three ways: through air gap regulation, rotary regulation, and composite regulation. Then, a test platform of MAMC was built to carry out experimental research on speed regulation model of constant torque load, quadratic rate load...
