“…Meanwhile, when the excitation force amplified by the torque fluctuation of the driveline resonates with the natural frequency of the torsion mode or bending mode of the drive shaft or the rigid body mode of the driveline [30], vibration is transmitted to the vehicle body, resulting in vibration and booming noises in the vehicle interior. To improve such resonance problems, various studies have been conducted to separate the natural frequencies of the driveline [31], [32]. However, this may adversely affect vibration in other driving regions due to the shift of the natural frequency [30].…”

In some applications such as electric vehicles, electric motors should operate in a wide torque and speed ranges. An efficiency map is the contour plot of the maximum efficiency of an electric machine in torque-speed plane. It is used to provide an overview on the performance of an electric machine when operates in different operating points. The electric machine losses in different torque and speed operating points play a prominent role in the efficiency of the machines. In this paper, an overview about the change of various loss components in torque-speed envelope of the electric machines is rendered to show the role and significance of each loss component in a wide range of torque and speeds. The research gaps and future research subjects based on the conducted review are reported. The role and possibility of the utilization of the computational intelligence-based modeling of the losses in improvement of the loss estimation is discussed.

When the emitter is flying in the air, it is easy to be disturbed by the external load, which causes the path deviation in the flight process. Therefore, dynamic performance of the emitter needs to be considered in the design stage. In order to study the influence of the positions of lumped masses on the dynamic characteristics of the emitter, a finite element model of a typical emitter is established. The first 20 orders free vibration modes of the emitter are calculated with different distributions of the lumped masses. Then, the optimal distribution of the lumped masses is obtained, which provides the theoretical basis for the structural optimization of the emitters.
