GAS SPRINGS
ABSTRACT
Gas springs provide controlled motion and speed for elements, such as lids and doors, that open and close. The absorption or damping action for gas springs can be compression or extension. In a compression gas spring the shock absorption or dampening occurs in the compression direction. In an extension gas spring the shock absorption or dampening occurs in the extension direction. Important physical specifications for gas springs include the cylinder diameter or maximum width, the rod diameter, mounting, and body materi..............etc

INTRODUCTION
Gas springs provide controlled motion and speed for elements, such as lids and doors, that open and close. They typically rely on the fluid dampening of a gas such as nitrogen in the cylinder. Important performance specifications for gas springs include absorber stroke, compressed length, extended length, maximum force (P1), and maximum cycles per minute
The absorption or damping action for gas springs can be compression or extension. In a compression gas spring the shock absorption or dampening occurs in the compressio..............etc

ABSTRACT

The holddown Spring is one of the major components of a fuel assembly for PWR. It holds the fuel assembly firmly seated down on the lower core plate and allows the FA axial movement caused from the irradiation growth of guide thimbles. Depending on the up-lift force of a fuel assembly, from 2 to 4 leaves are assembled to be a set of a spring pack and it is fixed on the frame of the top end piece by screw. The spring can deflect so greatly during operat..............etc

ABSTRACT
A gas spring is a type of spring that, unlike a typical metal spring, uses a compressed gas, contained in a cylinder and compressed by a piston, to exert a force. Gas springs are used in automobiles, where they are used to support the weight of doors while they are open. They are also used in furnit..............etc

DEAR SIR,

I AM THE STUDENT OF MTECH (CAD/CAM) AND I HAVE TO STUDY THE THE SUSPENSION SYSTEM & IN THIS SYSTEM LEAF SPRING PLAYS AN IMPORTANT ROLE. BY CHANGING MATERIAL I WANNA TO CALCULATE & ANALYSE THE CHANGES IN STRESSES & DEFLECTION.

TILL NOW DESIGNING PART OF THE SPRING IS ALMOST DONE BUT MY EFFORT NEED SOME GUIDANCE ABOUT THE SELECTION OF COMPOSITE MATERIAL SO, IF YOU ARE AWARE ABOUT THE WHICH MATERIAL SHOULD I SELECT IN ACCORDANCE WITH APPLICATION & COST. THEN PLEASE GIVE ME SOME INFORMATION REGARDING THIS.

THANKS & BEST REGARDS,
..............etc
