Property Analysis

Mechanical property analysis of circular hyperelastic polymer membrane under uniform pressure has been researched in this work. The polymer membrane material is assumed to be homogeneous and isotropic and incompressibility of materials has been considered. Based on the modified stain energy function from Gao and nonmomental theory of axial symmetry thin shell, finite deformation analysis of polymer membrane under uniform pressure has been proposed in current configuration and governing equations of polymer membrane have been achieved. By utilizing the boundary condition, theoretical results of governing equations have been obtained and vertical displacement distribution and stress distribution have been achieved. The results show that the constitutive parameternhas a strengthening effect on the polymer material and the constitutive parameterαplays a controlling role for the second strain invariantI2, which also has a strengthening effect on the polymer material. This research has revealed the deformational mechanism of polymer membrane and provided reference for the design of polymer membrane.

Magnetic Suspension System

This paper proposes an improvement method of zero suspension force performance using a special permanent magnet for a magnetic suspension device. The zero suspension force of a permanent magnetic suspension device is indispensable for floating off when the suspended object is stuck on accidentally. Generally, the magnetic suspension system using permanent magnet is difficult to realize the zero suspension force, since the permanent magnet cannot make its attractive force zero. However, the proposed magnetic suspension device has realized the semi-zero power suspension and semi-zero suspension force, which mainly consists of a disk-shape permanent magnet, two “F” shape iron cores, a suspended object, and an actuator. In the magnetic suspension device, since there is magnetic leakage, the suspension force could not be made exact zero. Therefore, in this paper, the zero suspension force will be improved using a special shape permanent magnet. The comparison results indicate that the zero suspension force is decreased about 80 percent.
