“…13,14 In addition to in-pipe robot design, studies on appropriate designs for three-dimensional flow structures have many applications. [15][16][17] Li et al 18 describes a multi-phase flow simulation for designing and controlling a passive magnetic levitation carrier system via the Taguchi method. Song et al 19 have conducted an optimal design of an internal flushing channel for a drill bit using response surface methodology (RSM) and computational fluid dynamics (CFD) simulations, achieving very good results.…”

In this work, the flow effects on an isolation plugging tool in a pipeline were numerically investigated using computational fluid dynamics. The study focused on optimal parameter design for the isolation plugging tool, which reduced the unsteady force effects on the x and y directions of the flow field. First, three-dimensional models of the isolation plugging tool and pipe were built. The velocity, pressure, and force analysis on the flow past the isolation plugging tool were investigated via computational fluid dynamics simulation. Second, a combination of design parameter ratios was selected using the Box-Behnken method for a series of numerical experiments. From the simulation results, three regression total force models were determined for the x, y, and z directions using response surface methodology. A modified genetic algorithm was proposed to optimize the design parameter ratios for the isolation plugging tool based on the regression models. The optimum parameter ratios were chosen and verified using the simulation results.

The application of fiber‐reinforced polymer (FRP) composite materials and structures in various industrial sectors is expanding significantly to meet the rising demand for efficient, reliable, and functional building materials. Using FRPs can be an excellent strategy for enhancing railway structures and equipment because of their high strength‐to‐weight ratio, tailorable mechanical properties, and suitable long‐term characteristics. However, the railway industry appears to be hesitant to adopt composite materials compared to other transportation sectors like aerospace. It seems that there is still a long way to go before FRPs reach their full potential in railway applications. The goal of the current study is to explore the current uses of FRPs in the railway industry and the significant challenges, obstacles and difficulties that must be overcome to put FRP‐based concepts into practice for structural and rail vehicle applications.Highlights Applications of FRPs in railway vehicles and rail lines are reviewed. Main challenges for utilization of FRP in railway industry are studied. Future trends and applications of FRPs in the railway sector are introduced.

Featured as an innovative powerless and low stiffness suspension approach, diamagnetic levitation technique has trigged intensive interest because of its potential applicability in miniaturized mechanical system. The foundation of diamagnetic levitation system lies in mathematical modeling, which is essential for operating performance optimization and stability predication. However, to date, few literatures concerning the systematic mathematical modeling has been reported. Herein, in this work, a systematic mathematic model for disc-shaped diamagnetically levitated rotor on permanent magnets array is proposed. Based on the proposed model, the magnetic field distribution characteristics, diamagnetic levitation force characteristics (i.e. levitation height and stiffness) expressions and the optimized theorical conditions for realizing stable levitation are achieved. Experiments are also performed to dig out the relationship between levitation height and levitation force. Moreover, the operating stability of rotor under different conditions is evaluated. The experimental results are well in accordance with the theorical predications, confirming the feasibility of this mathematic model.
