STABILIZER SYSTEM USING FMEA METHOD

Failure mode Effect S Cause O RPN

Drive mode does not be activated

Park mode does not be activated

Drive motor does not be activated

Swivel motor does not be activated

8 Stabilizer is not The users might complain it Battery does not transfer the power to power unit 3 21
folding into and try to fix it User interface does not inform the master control unit to
streamline on
park mode / work
opening on drive 7 Master control unit does not inform the battery to work
mode
Battery does not transfer the power to master control unit
Master control unit does not inform the sensors to work
İnclination angles do not be sensed

Sensors do not inform the master control unit about

inclination angle

Sensors do not inform correctly the master control unit

about inclination angle

It takes too much time to open/close the system manually

Power transfer is interrupted from battery to master control

System does not be opened/closed manually
Rotors do not rotate
Rotation direction of rotors is not correct
Rotation direction of rotors is same
