Abstract: One of the major difficulties in the multi-axis random vibration tests for satellite products is the determination of the test conditions. First, a theoretical analysis is made. Then, the currently used engineering processing methods are discussed, including the model related method, the simplification method, the cross-power spectrum design method, and the time-domain signal processing method. Finally, some suggestions for determining the conditions of multi-axis random vibration tests for satellite products are proposed from four perspectives, including the simplified processing, the telemetry data analysis, the simulation analysis, and the comparative study of the existed experimental data.
