摘要 ：
Aiming at the problem of low power density of the existing eddy current retarder, a New Toothed Coil Eddy Current Retarder (TC-EHR) is presented. The TC-EHR utilizes the space of one set of coils to achieve the magnetic flux that can only be obtained with two sets of coils in a conventional eddy current retarder. During operation, the TC-EHR creates a three-dimensional magnetic circuit between the stator, rotor and air gap. First, the structure and operating principle of the TC-EHR are introduced. Second, an equivalent magnetic pole principle model (one cycle model in the circumferential direction) was designed based on the principle that the magnetic flux is equal to that at each head of the complete model of the TC-EHR. Subsequently, the static electromagnetic field and the seemingly steady-state electromagnetic field finite element analysis of the TC-EHR were carried out. Finally, the test prototype was fabricated and bench tested. The braking performance and overexcitation characteristics of the TC-EHR were analyzed by comparing the test data with the finite element simulation. And by comparing with the traditional eddy current retarder of the same size, it is verified that TC-EHR has higher braking power. And compared with the normal excitation state, the braking torque of TC-EHR is improved by about 20% in the 2-fold overexcitation state.

摘要 ：
Aiming at the problem of large moment of inertia of the existing rotating electromagnetic shock absorber for armored vehicles, a new type of axially distributed lightweight rotor electromagnetic shock absorber (L-ESA) is proposed in this paper. It is composed of left and right symmetrically distributed stators, the rotor in the middle and permanent magnets (PMs). The road excitation is transmitted to the planetary gearbox through wheels, rocker arm and connecting rod, and transmitted to the L-ESA after speed increase. At the same time, the high speed rotating rotor of the L-ESA cuts the magnetic field lines and generates damping torque, so as to attenuate the vibration caused by road excitation. The electromagnetic field model of the L-ESA was established by 3-D finite element method (FEM), the damping torque of the L-ESA is predicted and the electromagnetic characteristics and damping characteristics are analyzed. The simulation results show that the damping torque can reach 295Nm at 2000rpm, which can meet the technical requirements of the vehicle.

摘要 ：
An energy-efficient magnetic track-eddy current composite brake (MT-ECB) for high-speed trains is proposed in this study. It has two modes: the magnetic track working mode and eddy current working mode. First, the structure and operating principle of the composite brake are introduced. Subsequently, a multiobjective optimisation process of the major structural parameters was conducted with the consumed PM volume, electrical excitation, and magnetic attraction force as optimisation objectives. A Kriging surrogate model for the MT-ECB was established. Optimal Pareto front solutions were acquired by adopting the non-dominated sorting genetic algorithm II (NSGAII), and the optimisation results were verified via a 3-D finite element simulation. After the optimisation of the MT-ECB, the consumed PM volume decreased by 18%, and the power consumption was reduced by 21%. The electric energy consumed per 1000 N of the eddy current braking force decreased from 4 kW to approximately 2 kW, resulting in a remarkable energy-efficient effect.

摘要 ：
In order to solve the problem of generator output voltage instability caused by mud flow instability, the electromagnetic damping generator (EDG) with stable output voltage is innovatively designed, and the contradiction matrix based on TRIZ theory. According to the invention principle "23 feedback" corresponding to "9 Speed" and "31 Harmful factors produced by objects", the structure scheme of EDG is proposed by coaxial assembly of generator and eddy current retarder (ECR). According to the technical index, the generator part is calculated theoretically. The accuracy of theoretical calculation and the feasibility of innovative design are verified by Finite Element Method (FEM). The output voltage and power generation efficiency of the generator and the braking torque of the ECR are calculated by FEM. The innovative EDG can adjust 40 V voltage to meet the design requirements.

摘要 ：
In order to solve the problem of the large moment of inertia of the existing rotating electromagnetic shock absorber for armored vehicles, a new lightweight rotor adaptive electromagnetic shock absorber (LR-AESA) is proposed in this paper. The LR-AESA consists of the left and right symmetrically distributed stators, a rotor in the middle and excitation coils. Secondly, based on the equivalent magnetic circuit method (EMC) and the Ampere loop theorem, and the interaction of the reaction magnetic fields between adjacent eddy current rings and the nonlinear effect of the interaction between the eddy current field and the original magnetic field are further considered, the air gap magnetic field distribution of the LR-AESA of the 10# steel rotor and the copper rotor at different speeds is derived, and the analytical expression of the damping torque is obtained. Finally, the validity of the analytical model was verified by comparison with results from the 3-D finite element method (FEM). The results show that the LR-AESA of the two material rotors can meet the requirements of technical indicators, but in the full speed section (200 similar to 2000 rpm), the copper rotor has the advantage of a wider range of the damping torque adjustment.

摘要 ：
To solve theproblems of an insufficient braking moment for the eddy current retarder at high speed, a small braking moment and slow response of the hydraulic retarder at low speed, and a low power density of the existing electromagnetic hydraulic retarder(EHR), a novel radially distributed electromagnetic-hydraulic retarder(R-EHR) was proposed. The R-EHR fully absorbs the advantages of the braking characteristics of hydraulic retarders and eddy current retarders. The cooling fluid is used to realize the braking of the hydraulic part. At the same time, it acts on the heating surfaces to improve the torque of the electromagnetic part. In this paper, finite element models of the flow field and electromagnetic field are established to predict braking performance. The braking performance of the R-EHR is obtained by bench test, the error between the simulation and experimental data is compared, and the experimental data are analyzed. The results show that the proportion of electromagnetic braking torque in the novel R-EHR is more reasonable. The braking torque increased by 26% and the power density increased by 37.5% at 2000 RPM compared to that of the EHR. The R-EHR can control the braking torque only by adjusting the current, thus simplifying the control system.
