SPRING LIFE CALCULATION

Highlighted

Re: SPRING LIFE CALCULATION

Dear sir,

SPRING LIFE CALCULATION

Is there any worked examples in calculating the mechanical spring life (energy storing device)

Eg: springs in computer keyboard's

springs in writing pen.

Dear sir,

           Tanks for ur Valuable reply..

Re: SPRING LIFE CALCULATION

Dear sir,

              I want to know the life of mechanical spring in computer keyboard the assume the force to hit the spring.

Re: SPRING LIFE CALCULATION

The only chance you have, is to ask computer manufacturers.

Re: SPRING LIFE CALCULATION

There are a lot of calculators out there, so implementing one in Mathcad is certainly possible.  To estimate the fatigue life of a particular spring you would need to know details of the spring (material, dimensions, number of coils), and details of the installation (installed length, compressed length, etc.

Generally keyboard designers target a specific life; 50 million key presses seems to be a common goal.
