Özet
A log-based stress-exposure proxy and map is presented for multirotor UAV battery post-flight review under field constraints where only pack-level telemetry is available. Maneuver intensity (gyro magnitude) and electrical loading (C-rate) are percentile-normalized and combined into a two-dimensional maneuver-load envelope. A core exposure budget is accumulated to form a hotspot map (BASE). Logged vibration severity is then introduced as a tunable co-exposure amplifier, yielding an amplified accumulation (EXT) and an incremental vibrationrelated component (EXTRA) that highlights where high vibration coincides with maneuver-load demand. For cross-mission comparability, a per-flight scaling factor is applied using an explicit conservative amplification anchor band. The framework is demonstrated on an open ArduPilot dataset through a detailed single-flight example and a multi-flight summary over 10 valid missions. Tests show that exposure growth is uneven and is often dominated by short, intense episodes. These episodes are summarized through Top- K event ranking with fixed context windows. The produced outputs are operational stress-exposure maps for localization and mitigation planning, rather than direct battery degradation-rate estimates.
