Herein we propose a research frame to understand and mitigate the impact of weather stressors (wind, rain, snow, ice, and fog) on AVs. A recently launched initiative to design and engineer an indigenous Canadian road vehicle serves as a background for this intended framework. The proposed frame consists of: (i) on-road testing and numerical (CFD) simulations to derive statistically significant critical weather conditions (weather design cases, WDCs); (ii) simulation of these weather conditions in the ACE climatic wind tunnel at Ontario Tech University, Canada in order to (iii) identify adaptive controls to minimize the effects of the WDCs on vehicles improving their aerodynamics, safety, and sensor functionality. This framework is intended to: (i) provoke discussions among the AV industry and research stakeholders in Canada and elsewhere and (ii) provide a context for future research in related areas such as AV aerodynamics, maneuverability, weather impacts (e.g. wind, rain, snow, ice and fog), sensors and soiling.","PeriodicalId":23285,"journal":{"name":"Transactions of The Canadian Society for Mechanical Engineering","volume":"103 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41245037","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}

Therefore, a novel torque vectoring control algorithm is proposed to lower energy dissipation and ensure lateral stability, which consists of a linear quadratic regulator (LQR) and a Proportion Integration (PI) control module in upper controller to calculate desired additional yaw-moment and total driving torque respectively for following desired yaw rate, side slip angle and longitudinal velocity. In addition, the stability objective function considering tires working load and the economic objective function considering working efficiency of IWMs and tires slip energy are established separately in lower controller. The fitness function of coordinating lateral stability and economy is obtained by phase plane method. Particle swarm optimization (PSO) algorithm with a superior initial population (SIP-PSO) is proposed to solve torque distribution coefficients for torque distribution of DDEV. Finally, simulation and hardware-in-the-loop (HIL) test results under DLC and SLC maneuvers on lower adhesion road indicate that the proposed algorithm can effectively lower the energy loss of IWMs working and tires slip when ensuring lateral stability under different working conditions.","PeriodicalId":23285,"journal":{"name":"Transactions of The Canadian Society for Mechanical Engineering","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45893542","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 effects of injection condition and dimethyl ether (DME) blending ratio on the pressure fluctuation characteristics are determined. The results show that the pressure fluctuation intensity determines wavelet packet energy distribution in the three sub-signals. The overall pressure fluctuation is reflected by sub-signal Sig1, which is composed of sub-signal Sig2 and Sig3. Sig2 exhibits medium frequency pressure fluctuations, and mainly occurs in the pressure rise stage and the pressure drop stage. Sig3 exhibits high frequency pressure fluctuations, mainly locates in the pressure stabilization stage. The pressure fluctuations at high injection pressure are more significant compared to those at low injection pressure. Biodiesel-DME blends display similar effects of injection pressure. With the increase of injection pressure, the mean energy and the standard deviation of Sig1, Sig 2 and Sig3 increase, especially those of Sig1 and Sig3. When DME is blended in the biodiesel, the pressure fluctuations for biodiesel-DME blends are more significant compared to biodiesel.

Given that a fault signal is also a form of audio signal, we extracted the characteristics of the mel spectrum from the original signal and applied it to a convolution neural network proposed in this paper. Focusing on the residual structure in the residual neural network (ResNet), we solved the gradient disappearance problem and accelerated the training of the model. The importance of each feature channel could be estimated adaptively using the squeeze-and-excitation network (SENet) considering the relationships between the channels. We examined the feature map of each layer using a multibranch residual network (MB-ResNet) to characterize the bearing fault signal. We used the multibranch residual structure to reduce the sense field of each residual and added a parallel local sensing module to train the model to recognize the weight of each input feature to either increase or reduce the influence of local features. Our experimental results show that the MB-ResNet is very good at extracting features, is robust, and capable of generalization.","PeriodicalId":23285,"journal":{"name":"Transactions of The Canadian Society for Mechanical Engineering","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41527944","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 of the analysis of variance (ANOVA) have been critically employed to assess the variation between the variables and within their levels for approaching the significant combination of parameters. The joints welded with MWCNTs-TiO2 coated fillers tendered a significant reduction in grain size (GS) along with high values of the tensile strength (TS). From ANOVA, it was determined that both the investigated parameters and their combined effect have created a significant response for GS reduction and increment in TS. The presented empirical regression quadratic model is validated for the adequacy of the projected results that were shown acceptable with the experimental investigated data. In addition, the desirability function approach is applied for the multiple response optimization (MRO) in yielding the desired responses of GS and TS with simultaneously providing the optimized set of process parameters.

Spectroscopy indicated small chromium and improper ratio of manganese to sulphur in IC samples. Improper ratio of manganese to sulphur in IC samples promoted hot cracking at grain boundaries, which results in intergranular corrosion. The microstructural results of G40 (air cooled) and G60 (water cooled) shown ferrite and martensite in different proportion. The deformed ferrite in G60 indicates inclination to corrosion and no proper stable layer of martensite was found. Percentage of martensite was not enough to retaliate intergranular corrosion. Highly pressurized water initiated pitting corrosion due formation of small pits on surface.

Besides, the remaining combustion ash from the testing process was analyzed using gaussian equations. The study conducted experiments through combustion in the FBC space. The result of experimentation from the combustion process with EFB fuel resulted in higher efficiency than OPM and PKS. The efficiency level of each fuel used is 12.77% EFB, 11.05% OPM, and PKS 10.63%. The analysis results for the highest temperatures were recorded from EFB fuels reaching 1,045oC. While the highest temperatures recorded from PKS and OPM were 875 oC and 934 oC, respectively, for measurements on M-1. As for the M-2 measurement the highest temperature was recorded on PKS fuel 935 oC, OPM 866 oC, and EFB 633 oC.
