Vibration based Static Monitoring of Rolling Element Bearing in High Speed Trains

Peng Chang Zhiqiang Xu Ning Li

Vibration based method has been widely used as a powerful tool to assist condition monitoring of rotating machines. In order to eliminate the indeterminacy induced by conventional manual detection of rolling element bearing in high speed trains, a vibration based static monitoring process has been proposed. Kurtogram algorithm is firstly used to remove the noise in the original vibration signal of rolling element bearings. Subsequently, envelope analysis is applied to extract characteristic vibration features of roller bearings. The practical test has proved the effectiveness of the proposed semi-automatic method for condition monitoring of axle box bearing in high speed trains.

Tube Electromagnetic Free Bulging Based on Internal Negative-External Positive Three-Coil System

IEEE Access (2020)

Li Qiu Chenglin Wang Ahmed Abu‐Siada Bin Wang Weikang Ge

Controlling the direction and profile of the electromagnetic force (EMF) is a key of improving the tube axial-uniformity and wall thickness during the electromagnetic forming process.In this regard, this article proposes a new tube electromagnetic-bulging topology using internal negative-external positive three-coil system.This structure is aimed at realizing effective bidirectional loading of axial and radial EMFs on the tube.An electromagnetic-structure coupling two-dimensional model is proposed to study the effect of the coil structure on the EF profile, bulging profile and the tube wall-thickness.The performance of the proposed method is compared with the traditional method through several performance metrics that include the electromagnetic force distribution cloud map, the tube bulging uniformity and its wall thickness.Numerical simulation results show that by changing the coil structure, the radial EMF profile can be effectively enhanced, and the free bulging contour of the tube can be further regulated.The additional axial EMF due to the proposed structure can promote the axial-flow of the material, thereby suppressing the reduction in the tube wall-thickness which is unavoidable using the traditional method.In comparison to the traditional single-coil system bulging, the maximum axial uniformity range of the tube is increased from 6.5mm to 35.2mm, and the wall thickness of the most severely thinned area is increased from 1.43mm to 1.77mm which verifies the effectiveness of the proposed method.

Manipulation of Deformable Linear Objects in Benchmark Task Spaces

2022 IEEE 18th International Conference on Automation Science and Engineering (CASE) (2022)

Peng Chang Rui Luo Mark Zolotas Taşkin Padır

Manipulation of deformable linear objects (DLOs) is a key robot capability in applications such as manufacturing, logistics, and healthcare. DLOs are commonly found in industrial and domestic environments in the form of cables, ropes, and wires. However, dexterous manipulation of these objects autonomously is computationally expensive due to their infinite degrees of freedom in 3-D space. Manipulation of DLOs is also typically constrained by the environment, which poses additional challenges due to restricted robot motions. In this study, we propose a method for automating the manipulation of DLOs in constrained spaces. The approach contains a geometric model of cable-like objects based on multiple features including point cloud, color, and shape. Given the estimated 3-D cable model and environment information, we propose a model-based planning methodology for manipulating DLOs in constrained spaces. We demonstrate the efficiency and robustness of our method by automating a cable threading task with real robot experiments using an assembly task board designed by the National Institute of Standards and Technology.

Analysis of coil temperature rise in electromagnetic forming with coupled cooling method

International Journal of Applied Electromagnetics and Mechanics (2020)

Li Qiu Kui Deng Yantao Li Xi Tian Qi Xiong

The long-life driving coil is the prerequisite for electromagnetic forming industrial application. Up to date, the temperature rise is one of the major factors that restrain its working life. For the purpose of reducing the temperature rise of the driving coil, this paper proposes a new coupled coo ling method, in which an extra cooling coil is placed on one side of the driving coil, then the Joule heating is coupledly transferred by delaying the breakover control of the driving coil. To achieve this purpose, a finite element simulation model of Electrical Circuit- Electromagnetic Field-Thermal Coupling in the plates setting of the electromagnetic forming is established, after which the influence rules of coil turns, cross-sectional area and materials of cooling coil on temperature rise are analyzed. Then, this paper also establishes a coupled cooling circuit model, in which the influence of cooling coil structure parameters on the Joule heating of driving coil is analyzed. Furthermore, Simulation results show that effective Joule heating transfer can be reached by the best optimization scheme of the cooling driving coil. Specifically, the average temperature rise reduces by 13 degrees, namely 22.8% by using this new method.

International Journal of Applied Electromagnetics and Mechanics (2018)

Li Qiu Yijie Yu Tao Li Guang Tong Feng Pan Su

To improve the heating efficiency of the induction cooker system, this paper adopts the method of introducing an adiabatic layer between the pot bottom and the coil. By using COMSOL software, the electromagnetic - thermal coupling model of the induction cooker is established to analyze the effect o f the adiabatic layer on the food temperature and coil temperature, and finally the heating efficiency is explored. The obtained simulation results show good agreements with the experimental results, and then the effectiveness of the proposed method is verified.

Key Points of Cast-in-Place Small Box Girder Concrete Construction of Baishui Lake Bridge

Advances in transdisciplinary engineering (2024)

Yajun Wang Lang Zhou Lin Xia Peng Chang

Due to the restriction of site and cost, no prefabricated beam yard has been built in this project, but cast-in-place. The construction of cast-in-place box girder requires on-site construction and waiting for the solidification of concrete, which takes a relatively long time and cannot be carried out quickly. The construction site conditions of cast-in-place box girder and the ability of construction personnel are different, which are prone to quality problems and cause potential safety risks. Therefore, when pouring small box girder concrete on the support, preparations should be made, including the control of raw material, concrete mix ratio design, formwork reinforcement, and technical disclosure before construction; secondly, the control of the pouring process, pouring method, pouring sequence, and concrete maintenance and mold removal, so as to ensure the quality of box girder concrete after pouring meets the requirements.

Research on Vault Settlement during Three-Step Tunnel Construction Process Based on Sandstone Rheological Experiment

Materials (2024)

Peng Chang Yong Qu Helin Fu Cheng-Da Xie Guiqian Cao

Tunnel stability is influenced by the rheological properties of the surrounding rock. This study, based on the Ganshen high-speed railway tunnel project, examines the rheological characteristics of siltstone and sandstone through laboratory tests and theoretical analysis. Rheological curves and parameters are derived, revealing the time-dependent deformation mechanisms of the surrounding rocks. A numerical simulation model is created using these parameters to analyze deformation and stress characteristics based on different rock levels and inverted arch closure distances. Results indicate that sandstone follows the Cvisc model, with the Maxwell elastic modulus increasing under higher loads while the viscous coefficient decreases. The vault displacement is mainly affected by the surrounding rock strength; lower strength leads to greater displacement, which also increases with the closure distance of the inverted arch. These findings are crucial for determining the optimal closure distance of inverted arches in sandstone conditions.
