During the cutting process, different conical pick structures can have significant impacts on the cutting performance of the equipment, and the wear resistance of the conical picks will directly affect the efficiency and reliability of the equipment. In this paper, a bionic dimple-structured conical pick is designed, and a mathematical model of the dimple structure is established. The cutting performance, self-rotation performance, and wear resistance of dimple-type picks (DTPs) and ordinary-type picks (OTPs) are studied using the discrete element software EDEM and the dynamic analysis software ADAMS. The results show that during the cutting process, the trend of rotational torque over time for both types of conical picks first increases and then decreases, with the maximum rotational torque of DTP being greater than that of OTP, indicating that the self-rotation performance of DTP is superior to OTP. Compared with OTP, DTP exhibits a smaller total wear amount and better wear resistance performance. When comparing end plates equipped with DTP to those with OTP, the end plates with DTP have a smaller load fluctuation coefficient, lower cutting resistance, lower specific energy consumption for cutting, and greater total coal mass.","PeriodicalId":23285,"journal":{"name":"Transactions of The Canadian Society for Mechanical Engineering","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135968164","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mass fraction of the ZrO2 particles was varied from 4 % to 8% and 3 sets of solid cylindrical rods with Al4%ZrO2, Al6%ZrO2, and Al8%ZrO2 were prepared using the stir casting method. The upsetting process was simulated and an equation for predicting hardness was developed from the equivalent strain distributions. Artificial neural networks(ANN), Multilinear regression (MLR) along with equations developed from FE analysis were used to train the model for regression analysis considering the principal stresses, friction factor, anisotropy ratio, effective strain, and hoop strain as input and the magnitude of hardness as output parameters. Regression analysis reveals that ANN (Tri-layer network), XG Boost, and multilinear-regression algorithms are the best suitable for the given data sets with a root mean square (R2) greater than 0.95. XG Boost, ANN (narrow), and SVM are linear and are the most recommendable classifier algorithms for the current investigation.

First, the digital features of the contact pattern were extracted, and the equivalent misalignment was obtained by an optimal method according to the minimum deviation of the contact path. Second, a pinion target surface whose performance under misalignment was consistent with the original gear in standard position was built, and a pinion surface with good meshing performance under misalignment was redesigned with equivalent misalignment. Third, the flank modification was carried out to cut down on the loaded transmission error of gear under misalignment. Through simulations, it is found the transmission error and the contact path of redesign gear considering misalignment were the same as original gear in standard position. The loaded transmission error amplitude of original gear under misalignment was 43.91% higher than original gear in standard position, and the loaded transmission error amplitude of redesign gear after optimization under misalignment was 44.73% lower than original gear in standard position and 61.60% lower than original gear under misalignment. The tooth surface stress of redesigned gear after optimization under misalignment was also significantly improved. This proposed redesign method, which considers misalignment on the basis of ease-off, can greatly improve the loaded meshing quality of gear under actual working conditions.","PeriodicalId":23285,"journal":{"name":"Transactions of The Canadian Society for Mechanical Engineering","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136061132","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thermoelectric refrigeration is an innovative way to use additional energy to cool and reserve cooling. In this research, a Photovoltaic-thermoelectric refrigeration system capable of sustaining vaccine storage within the limit of 2 to 8 ℃ has been established by experimentally optimizing its volume and performance. The design specification is to cool the volume using forced convection to the desired temperature range in less than thirty minutes and sustain retained heat for at least the next hour. The experimental research is divided into two stages: the first determines the optimal volume of vaccine storage under different testing conditions using only grid power, and the second analyses storage performance using solar energy through PV integration. The solar direct drive and the solar drive with battery support have been timed, revealing a holding period of 4 hours 46 minutes and 5 hours 29 minutes, respectively. The refrigerator's design criteria, prospective characteristics, and final design are all thoroughly highlighted. Finally, we conclude that this research will likely benefit the modelling and analysis of thermoelectric cooling systems.","PeriodicalId":23285,"journal":{"name":"Transactions of The Canadian Society for Mechanical Engineering","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2023-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49190816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results show that, under the braking condition, the interface has the stick-slip motion, indicating that the system is in the state of instability; the longitudinal relative slip is unevenly distributed, the peak position of the initial corrugation has a large longitudinal relative slip, and the transverse relative slip in the initial corrugation area is significantly larger than that in other areas, indicating that the initial corrugation will continue to develop and have a remarkable transverse wear trend. Under the non-braking condition, there is no stick-slip motion at the interface, and the longitudinal and transverse relative slip values are less than the corresponding results under the braking condition. The cause of corrugation in the vehicle braking section is the wheel-rail unstable stick-slip motion triggered by the vehicle braking, and the fixed operating mode of the train provides the wavelength-fixing condition for the development of the initial corrugation, which leads to its continuous deterioration.","PeriodicalId":23285,"journal":{"name":"Transactions of The Canadian Society for Mechanical Engineering","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2023-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41660559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
