Special Issue Information

Dear Colleagues,

Humans are responsible for protecting the environment, and creating a new economic model of sustainable development is our shared goal. Manufacturing accounts for one third of the global energy consumption, and the COVID-19 pandemic highlighted its important role of improving the quality of our lives. Therefore, manufacturers need to use an intelligent approach in product design, manufacture, and delivery in the supply chain to achieve sustainability. Although many researchers in academia and industry have conducted long-term research on intelligent manufacturing and achieved impressive feats, small- and medium-sized enterprises encounter problems with sustainable development such as labor shortages and an inability to sustain unmanned practices. With uncertainty in the economy, enterprises have higher requirements for the sustainability of intelligent manufacturing.

It is worth pointing out that no single solution can be adapted to all manufacturing industries. In the process of improving the sustainable performance of intelligent manufacturing, each manufacturing system has become unique. Even large manufacturers have dissimilar experiences between similar production lines in different factories, . Each case needs to be customized according to the characteristics of the factory and the knowledge base. The objective of this Special Issue is to gather state-of-the-art research on the recent advances in the field of sustainable science and technologies in intelligent manufacturing.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but not limited to) the following:

(1) Sustainable development mode of intelligent manufacturing;

(2) Unmanned condition monitoring with equipment;

(3) Intelligent fault diagnosis;

(4) Sustainable intelligent operation and maintenance;

(5) Sustainable education in intelligent manufacturing;

(6) AI-enhanced sustainable development modes in intelligent manufacturing;

(7) Sustainable development case in intelligent manufacturing;

(8) Advanced quality management methods in intelligent manufacturing.

I look forward to receiving your contributions.

By effectively integrating traditional engines with reciprocating plunger pumps, the constrained piston hydraulic engine can simultaneously output hydraulic energy and rotational mechanical energy, which effectively solves the problems of the complex structure, long power transmission chain, and low energy conversion efficiency of traditional power sources. Based on a certain single-cylinder diesel engine, a single-cylinder axial constrained piston hydraulic engine was designed, and its thermal–mechanical–liquid coordination mechanism was studied and analyzed in-depth. A mathematical model of the thermal–mechanical–liquid coupling working process of the single-cylinder axial hydraulic engine was established, and the conversion mechanism and output of the three types of energy, thermal, mechanical, and liquid, were simulated and analyzed. The results show that under the premise of improving the overall efficiency, the constrained piston hydraulic engine can effectively output mechanical–hydraulic dual-element power, and its combustion characteristics and output power performance indicators meet the expected design requirements. The maximum amplitude difference of the output hydraulic oil flow rate reaches 248 L/min, and the flow rate fluctuates greatly, so it is necessary to adopt methods to suppress the flow rate pulsation to ensure the reliability of the output flow rate.

Due to various factors such as manufacturing, assembly and operation, the motor air gap will be uneven in the circumferential direction, resulting in the air gap eccentricity having a longer air gap on one side and a shorter air gap on the other side, which affects the normal operation and service life of the motor. This paper analyzed and compared the applicability of linear and nonlinear calculation methods of unbalanced magnetic pull. Based on the method of finite element analysis, the unbalanced magnetic pull of motor rotor under static eccentricity, dynamic eccentricity and compound eccentricity faults were calculated, and the influence of eccentricity on unbalanced magnetic pull was compared, respectively. The results showed that when the motor has static eccentricity, the main components of unbalanced magnetic pull on the rotor are zero frequency and twice the electrical frequency. When the motor has dynamic eccentricity, the unbalanced magnetic tension component of the rotor is mainly frequency conversion. When the motor has two faults at the same time, the unbalanced magnetic pull has zero frequency, rotating frequency and double electric frequency components at the same time. With the increase in the relative eccentricity, the frequency components of the unbalanced magnetic pull under the three faults increase. An air gap eccentricity fault widely exists in motor equipment. When the unbalanced magnetic pull increases to a certain extent, the rotor will be pulled towards the stator, causing the occurrence of rub-impact phenomenon, and seriously threatening the safe operation of the system. In this paper, the numerical analysis method and finite meta-computing method were used for the first time to analyze and compare the unbalanced magnetic pull on the rotor of permanent magnet synchronous motor under three kinds of air gap eccentricity faults. The results showed that the characteristic frequency amplitude of the unbalanced magnetic pull calculated by the two methods is relatively close. Therefore, it is of great significance to carry out calculation and analysis of the unbalanced magnetic pull force under the air gap eccentric fault of the motor. Full article
