The Taguchi-based experiments has been designed and carried out to determine the suitable ball burnishing and ultrasonic vibration-assisted spherical polishing parameters, respectively. The effectiveness of the proposed combination of the ultrasonic polishing parameters has been justified by the verification experimental results. The optimal ultrasonic vibration-assisted polishing parameters were as follows: the amplitude of 10μm, the frequency of 23 KHz, the spindle speed of 5,000 rpm, the abrasive diameter of 0.3 μm, the feed rate of 60 mm/min, the stepover of 20 μm, the depth of penetration of 180 μm, the abrasive concentration of 1:10, based on the experimental results. The surface roughness of the polished test specimens could be improved from the burnished surface roughness Ra 0.122μm to Ra 0.022μm. The improvement of the volumetric wear of the polishing ball was about 62.5 % using the vibration-assisted polishing process compared with the non-vibrated polishing process.","PeriodicalId":217521,"journal":{"name":"2022 25th International Conference on Mechatronics Technology (ICMT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130311302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The virtual synchronous machine (VSM) is a power electronic converter with the dynamic characteristics of the traditional synchronous machine. Synchronverter is a kind of VSM with dynamic reproduces of the traditional synchronous generator (SGs) and has a wide range of applications in distributed generation systems and microgrids. This paper reviews the existing and current developments of UAVs and introduces the Gasoline-electric hybrid propulsion system (GEHPS) for UAVs. The advantages and disadvantages of the three configurations of GEHPS are discussed. And the series GEHPS is selected as the research topic in this paper. The feasibility of using the synchronverter as a permanent magnet SGs rectifier for a series-connected GEHPS is then explored. We demonstrate the performance of our AC-DC converter through a series of simulations and compare it to the performance of currently existing systems. The results show that the new synchronverter-based converter enables the DC bus voltage to have better performance in terms of output active power oscillation and stability.","PeriodicalId":217521,"journal":{"name":"2022 25th International Conference on Mechatronics Technology (ICMT)","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117276920","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the high cost of time, labor, and equipment required for quality inspection in mass production, batch inspection is often used instead of full inspection, often resulting in difficult quality control. To achieve the goal of quality assurance, this study proposes a virtual measurement technique based on a real-time multi-quality prediction neural network combined with an autoencoder network (AE) and multilayer perceptron network (MLP). The main research content is that through sensing, quality indexing, and automated feature extraction technology, the captured data can be extracted, and the dimensionality reduction of the data is beneficial to the training of the MLP model. Experimental case studies show that the method can in-time predict the residual stress distribution, weight, and geometric dimensions of plastic parts, and the model prediction error (root mean squared error) is less than 5% of the total tolerance. In particular, the required prediction time is less than 0.24 s. The performance of the predicted residual stress distribution is highly similar to the actual picture. Further, the feature codes extracted from the AE model can be used to verify the residual stress quality of the molded part.","PeriodicalId":217521,"journal":{"name":"2022 25th International Conference on Mechatronics Technology (ICMT)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121636161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The PFC functionality is realized by designing the inductor in the modified stacked boost converter subcircuit in discontinuous-conduction-mode (DCM). Besides, the power switch features zero-voltage switching (ZVS), which reduces switching losses and improves the efficiency of the proposed driver circuit.This paper has completed the development of a 100W (36V/2.77A) prototype driver circuit, and tested the experimental results when the input mains line voltage is 110 V. According to the test results of the single-stage AC-DC driver circuit, the power factor is greater than 0.99, the total harmonic distortion factor of the input current is less than 6%, and the circuit efficiency is greater than 89%. Therefore, satisfactory experimental results demonstrate the functionality of the proposed driver circuit for powering the LED projection lamp.","PeriodicalId":217521,"journal":{"name":"2022 25th International Conference on Mechatronics Technology (ICMT)","volume":"2 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133219565","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
