“…In a basic vibrator, this force is provided by driving an actuator that moves a payload with respect to a base plate, which is in contact with the ground [7]. In contrast to hydraulic actuators, the linear electric motor performs equally well over the whole frequency range, especially at the low frequencies, making a small amount of signal distortion and can track various force-time profiles [8]. The usage of linear electric motors in seismic shake tables has enormously increased in the last years thanks to the aforementioned advantages [9].…”

The progress in material and manufacturing technologies enables the emergence of new research areas in electromagnetic actuator applications. Permanent magnet (PM) linear motors are preferred to achieve precise position control and to meet the need for high dynamic forces in the seismic shake tables that are used in analyzing reactions of structure models. The design approaches on the linear motors used in the seismic shake tables may vary depending on the desired force, stroke and acceleration values. Especially, the maximum width, the maximum depth, the maximum linear motor length in longitudinal direction and the maximum travelling distance parameters are the primary design criteria in seismic shake table drive systems. In this paper, a design approach for a linear PM brushless direct current (BLDC) motor with high force/volume, force/weight and force/input power ratios is developed. The design was analyzed using two-dimensional (2D) and three-dimensional (3D) finite element method (FEM) approaches through the ANSYS Maxwell software. The mathematically designed linear BLDC motor was manufactured and subjected to displacement, acceleration and force tests that are used in seismic analyses. The results of the experimental tests validate the convenience of the proposed design approach and the selected parameters.

“…A precise model is needed for the physical simulation to incorporate the essential dynamics of the information transmission process of BITS [17][18][19], and the FEM that provides accurate numerical approximations can be one of the best choices [20][21][22]. In this paper, the 3D-FEM [23] has been used to investigate the magnetic field distribution and the voltage induced in the balise receiving antenna, as shown in Figure 3.…”

Abstract-As key components of the train control system, balise and Balise Transmission Module (BTM) cooperate with each other and fulfill the ground-train information transmission to ensure the safety and reliability of train operation. Aiming at the requirements for future developments of high-speed railway, this paper builds the model for the dynamic transmission process of the balise tele-powering signal using finite element method and electromagnetic field theory, respectively. The paper analyzes the change law of the magnetic flux density distribution within the balise receiving antenna, and derives expressions for the balise induced voltage amplitude envelope based on train speed. Then, the paper carries out the performance optimization to the existing balise system from two perspectives of the balise mounting style and the BTM mounting height. Experiments show that the proposed optimization measures can substantially enhance the system's adaptability to the ever-increasing train operation speed from the existing 448 km/h to 523 km/h. Furthermore, a potential optimization scheme with respect to the BTM mounting angle which enables huge promotion of the system performance is also discussed and proposed.

“…This method approaches the problem by reducing errors [18]. FEM is used in different researches for various purposes such as modeling and parameter identification [19][20][21][22][23][24][25]. An acceptable solution from Maxwells equations for most practical cases is neither possible nor accurate.…”

Abstract-Inductive power transfer is recently a common method for transferring power. This technology is developing as the modern technologies need to get more efficient and updated. The power transfer efficiency has potential to get better. There are different ways to achieve a desirable efficiency. In this paper, a suitable geometry of a coil for transferring power as a transmitting coil is examined. In this work, three types of geometries are designed. Frequency analysis at frequency range (10 kHz-50 kHz) is done to investigate behaviour of various geometries. Magnetic field, electric field, magnetic flux density, and current density for various geometries are presented and compared. Magnetic flux density is measured via an experimental setup and is compared to simulated one to verify the validity of simulation results.
