3.3.3

SINE VIBRATION
Purpose: To ensure Payloads are compatible with loads imparted on primary and secondary structures with modes <
100 Hz.
The maximum predicted sine vibration environment is defined in Table 3-3. This environment is defined for Payloads with Q ≥ 10 in Rideshare Plate and Starlink Adapter configurations, and may be notched at primary mode(s) to stay within the design load factors defined in Section 3.3.2.
Verification: Testing is ADVISED to the sine vibration test levels and durations defined in Table 3-15 in accordance with the MPE defined in this section.

ACOUSTIC
Purpose: To ensure Payloads are compatible with acoustic environments inside the Launch Vehicle fairing. Note that most Rideshare sized Payloads are driven by structure-borne random vibration (Section 3.3.6) and not by direct acoustic impingement. The maximum predicted acoustic environment, defined as the spatial average and derived at a P level, is shown below in Figure 3-3 . Table 3-4 and Table 3-5 defines the environment in third octave and full octave respectively. A
Mission-specific analysis will not be provided by SpaceX.
