However, these methods only work with single faults and cannot diagnose compound faults because compound fault data is often unavailable in practice. To address this problem, this paper proposes a zero-shot learning-based bearing fault diagnosis method for compound defects. The proposed method utilizes an autoencoder network to observe the attributes of single faults and then estimates the attributes of compound faults. Afterward, a mapping from the data space to the attribute space is established to predict the attribute output of the data. The attribute output is then compared with prior attributes to determine the type of bearing fault. Verification experiments were conducted on HUST bearing dataset.

A prototype of the active steering bogie was installed on the test train, and noise reduction performance by active steering control was measured in curved sections of a commercial line with a radius of curve of 300 m or less. The results of the test run confirmed that both the wheel and car interior noise were reduced when active steering control was applied, compared with the case where it was not applied. According to the test results in the curved section with the most noise reduction effect, the equivalent noise level was reduced by 6.6 dB for wheels and 4.7 dB for the car body by active steering control. In addition, analyzing the frequency characteristics by wheel steering control has confirmed that the squeal noise mode generated in the 300 to 2000 Hz band during curve running was significantly reduced.

This paper proposes a method to approximate the terminal error of a redundantly actuated parallel manipulator by taking the minimum terminal error among all corresponding nonredundant counterparts. The local Frobenius norm index (LFNI) is proposed to estimate the expectation of terminal error. Additionally, the global Frobenius norm index (GFNI) is introduced to describe the worst case of terminal error in the workspace, which is then used for the optimum design of a RPU-UPR-2UPU redundantly actuated parallel manipulator. After the optimum design, the average root mean square error of the manipulator is reduced. Furthermore, a control mode determination strategy for allocating force/position control to a certain chain is also proposed to minimize the terminal error, whose effectiveness is validated through simulation.</p>","PeriodicalId":16235,"journal":{"name":"Journal of Mechanical Science and Technology","volume":"24 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142225507","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}

Accordingly, research on the robot’s localization using GPS, 3D LiDAR, and Vision has been actively conducted. However, there is a limitation in that it is difficult to locate robots in indoor spaces where signals are disturbed by walls or ceilings, or in areas where sufficient environmental information cannot be obtained. This paper introduces the robot’s position estimation method to overcome these environmental problems by using sensor fusion in an indoor tennis court. We propose a localization method that has low latency performance and high location accuracy through the use of Kalman filters to fuse data from wheel odometry and visual-inertial odometry. To evaluate its performance, this method was compared against wheel odometry, visual-inertial odometry, and LIO-SAM after the robot completed three rectangular paths. The resultant mean absolute errors in the x and y directions were 1.908 m and 0.707 m for wheel odometry, 1.169 m and 1.430 m for visual-inertial odometry, and 0.400 m and 0.383 m for LIO-SAM, respectively. In contrast, the wheel-visual-inertial odometry introduced in this study reported errors of 0.209 m and 0.103 m in the x and y directions, respectively, indicating superior accuracy compared to the other algorithms. This underscores the effectiveness of the proposed method in indoor environments where signals can be obstructed by walls or ceilings, or in areas lacking abundant environmental information.</p>","PeriodicalId":16235,"journal":{"name":"Journal of Mechanical Science and Technology","volume":"42 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142225531","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 conjunction of the PPC and barrier Lyapunov function in the DESO-CFAPPC not only prevents violation of output constraints of the barrel, but also prevents the complex calculation caused by the logarithmic ETF in the traditional PPC. The adaptive laws are constructed to estimate uncertain parameters. The DESO further estimates the unknown velocity, mismatched and matched model uncertainties.

To avoid excessive nonlinear calculations, a Kriging-based strategy is adopted for reliability sensitivity analysis, allowing for rapid estimation of nonlinear responses.
