Chinese Academy of Medical Sciences researched a temperature distribution of implantable centrifugal maglev blood pump, and found that the highest temperature appears at the motor windings[6].
For example, there have too much assumptions in calculating magnetic force, force-current and force-displacement factor; two-dimensional finite element method is usually used for calculating the spacial electromagnetic field distribution, while the axial distribution is ignored; Although a few researcher use three-dimensional finite element method, they usually do not take into account the nonlinear permeability and magnetic saturation of magnetic materials.
Permanent magnet material is the same as the axial bearings, single air-gap length is 2mm, the coil turns is 40, and the maximum current is 1A.

Aluminium alloy materials in Chinese load-bearing structures are mainly used in aluminium roof structures, like shells and domes, and supporting frame structures of all kinds of curtain walls.
With the wide application of aluminium structures, research on the aluminium alloy materials and the aluminium columns are increasing.
With the rapid development of aluminium structures, more and more demands are brought for the study of aluminium materials and members.
Fig. 3 Cyclic loading system For comparison purposes, the static bearing capacities and the lengths of three kinds of specimens with different materials were set to exactly the same, i.e., 286 kN.

The thrust in drilling of Ti-6Al-4V is much greater than that in S50C, whereas the torque is similar for both materials.
Meanwhile, another prominent high frequency component is analyzed in drillings of both materials.

Bronze-based composite materials are well known for use as friction materials.
In the research described in [4-6], prealloyed bronze powders were used for forming porous bronze materials.
Porous bronze has a tailorable porosity level which can be used for producing filters or as a matrix for friction materials.
The sample sintered for 60 min was 83% of theoretical density, which is sufficient given that friction materials are not often sintered to full density.

Blunt grits will be more difficult to penetrate into workpiece materials leading to high proportion of rubbing and ploughing in grinding.
The AE signal can easily pick up an event occurs in materials that are related to grinding burn [10].
The experiments aimed to provide grinding AE signatures in relation to grinding temperature on grinding aerospace materials (Inconel 718).
