Begin by Understanding Failures
What model does the Dog use?
RGB waves…. (Intention, Behaviour, Events)
S^2 = B => E• B wave G wave R wave
• Stimuli x Structure = Emergent Behaviour Events (failures, success)
• Stimuli = {F, R, E, T, H, L, S} (both external & internal)• Structure = {m, k, c, f, p, s} • Behaviour = {S.E, K.E, A.P, Turbulence, Resonance, Surface, Noise, Entropy}
• Creative Response to Plan/Improve = {+, -, /, x, dy/dx,∫, 0, 1/x, >, <, =>, …}

Dynamic Representation of the failure mechanism :
Space Align
Crack
Friction Surface Spalling Low cycle fatigue
Stress (HZ) High cycle fatigue
L2
Looseness of sleeve brg.
Coupled 1.Resonant frequencies (warning)
2. Increase in damping factor (Warning)
3. Pink noise (Alarm & stop)
Displacement & velocity signatures Wear debris analysis (Gear contact pattern & spalling
particles) Acoustic emission
Time
Planning & Improvement • Change oil from SP 320 to Servomesh 320 • Use silica gel breather • Electrostatic cleaner • Al-bronze bush • Drill a hole in the end cover of the lower bearing• …..
