Flexible steel plates have been widely used for industrial products. Since flexible steel plates are currently conveyed by roller conveyance, which causes fine scratches, a method is required to convey the steel plate non-contact by magnetic levitation to prevent quality deterioration. The levitation method performed by the authors utilizes the attractive force from electromagnets.

In this paper, we design a novel snap-fit mechanical metamaterial. Compared with traditional energy-absorbing structures, the snap-fit structure has the characteristics of repeatability and recoverability. We reveal the energy absorption characteristics by theoretical analysis and numerical simulation, and we analyze the influence of related parameters on the energy absorption effect. The results show that the energy absorption effect of the structure is mainly affected by the elastic deformation of the material and the friction energy dissipation between the components. The study provides important support for the future design of energy-absorbing mechanical metamaterials.

The magnetic bearing of the total artificial heart is investigated to reduce the device size. The attractive force production performance of the double-bias hybrid magnetic bearing, DHMB, and the single-bias hybrid magnetic bearing, SHMB, is investigated using three-dimensional finite element method analysis. The thickness of the MB may be reduced by 1 mm, which is 20 % of total thickness, with the SHMB with keeping the magnetic bearing performance.

A finite element model is established to study the mechanism of out-of-tolerance of the liquid-filled tank in this work. The out-of-tolerance phenomenon refers to the difference between the expected applied load and the actual measured load during vibration testing of nonlinear structures. It is very meaningful for effective vibration testing of such structures by using of the electromagnetic vibtaion table. The simulation model is established in Abaqus which can provide the smoothed particle hydrodynamics method to solve the transient motion of liquid. The simulation results are consistent with the experimental results, which demostrates the correctness of the numerical method. The influence of the amplitude of the external excitation and the height of the liquid level on the out-of-tolerance situation are also analyzed.
