MECHANICAL QUALIFICATION TESTS IN THE GOCE PROJECT

摘要

The GOCE Assembly Integration and Verification (AIV) approach is established and implemented in order to demonstrate to the customer that the satellite design meets the applicable requirements and to qualify and accept it from lower level up to system level. The driving keywords of "low cost" and "short schedule" program, call for minimizing the development effort by utilizing off-the-shelf equipment combined with a model philosophy lowering the number of models to be used. The paper will deal with the peculiarities of the optimized environmental test approach in the GOCE project. In particular it introduces the logic of the AIV approach and describes the tests performed at system level within the SM mechanical qualification test campaign, outlining the Sinusoidal vibration test, the Quasi Static test performed in the frame of the SM Sine Vibration test, the Vibro Acoustic test, Pyro Shock and Separation Test and the Modal Survey by Sinusoidal low level runs. Furthermore, the deletion of the Sine Vibration test on PFM model will be described. Finally, the paper highlights how the Model and Test Effectiveness Database (MATEurD) can be utilized for the prediction of new space projects like the GOCE Satellite.
