https://accendoreliability.com/the-bath-tub-curve-explained/ https://accendoreliability.com/the-bath-tub-curve-explained/ is an interesting breakdown of bath tub curve dynamics for those curious!
- rtkwe 1y agoWonder if you could game that in theory by burning in the components on the surface before launch or if the launch would cause a big enough spike from the vibration damage that it's not worth it.
- vidarh 1y agoI suspect you'd absolutely want to burn in before launch, maybe even including simulating some mechanical stress to "shake out" more issues, but it is a valid question how much burn in is worth doing before and after launch.
- 0xffff2 1y agoVibration testing is a completely standard part of space payload pre-flight testing. You would absolutely want to vibe-test (no, not that kind) at both a component level and fully integrated before launch.
- btown 1y agoPSA: do not vibe-code the hardware controller for your vibration testing rig. This does not pass the vibe test.
- dapperdrake 1y agoMaybe they are different types of failure modes. Solar panel semiconductors hate vibration. And then, there is of course radiation trouble. So those two kinds of burn-in require a launch ti space anyway.
