I am currently running a shaker test to validate the change from a stell gasket to a fibre gasket. The shaker is running at the resonant frequency of the structure for 160,000,000 cycles at an acceleration level about 7*the level seen by the component in service.

The test that we are doing is not required to be related to actual time in service but it would be quite nice to quote this however the carrier material of the gasket is quite new and as of yet i have no material properties. Can anyone suggest a way to convert the cycles on the shaker to cycles in service?

Many Thanks
