| Abstract: | This paper presents some method for the design of the fixture for the force limited vibration test and the validation of force measurement device (FMD). Based on the satellite force limited vibration test, the cause of the force measurement error is discussed. It is shown that the error can be reduced to 10% or less by improving the acceleration factor and the signal to noise ratio, which proves the effectiveness of the FMD is effective. |
