Isolation control analysis is carried out for Kewitte latticed shell in which all horizontal pin supports were replaced by spring supports or damped spring supports.

Isolation control analysis was carried out for geodesic latticed shell in which all horizontal pin supports were changed as spring supports or damped spring supports.

In this paper,the BSS is simplified as a curve beam with elastic supports,where the actions of strut and string are simulated as spring supports.

[WTBZ]The paper briefly specified what role the spring bracket played as a part of air suspension system.

Aiming at the questions that the car spring plank exists at present, we utilize the existing production which is about the deformation rule and the forming technology of magnesium alloy AZ31 and the experiment conditions of the precision forming research center, and further study the extrusion technology of magnesium alloy AZ31 spring plank and the structure and properties of product.

Using the experiment conditions of the precision forming research center and theforthcoming researching which is on the deformation regulation and formingtechnology of magnesium alloy, combined with the questions that the car spring plankexists at present, studied the Isothermal extrusion technology of spring plank ofmagnesium alloy.
