Description
Lei Mou, Jinjin Sun, and Jie Wu simulated this 2026 shaking problem in rack-climbing lift platforms, the work decks that crawl up building faces. Treating the whole structure as rigid blocks misreads its vibration. The team built a coupled model mixing rigid bodies with flexible parts, using a reduction trick to keep the computation light, and ran it across four modeling styles.
Vibration sideways along the rack dwarfed the other directions, peaking at seven millimeters during startup, several times the alternatives. The fully coupled model gave the smoothest, most realistic response, confirming the simpler models' inadequacy. Parameter sweeps over speed, load, off-center loading, and braking time followed. The analysis guides designers toward platforms that do not rattle their riders.
